Before describing embodiments of the present application, some terms referred to in the embodiments of the present application will be first defined and described.

URL: the Chinese name Uniform resource locator is a concise representation of the location and access method of resources available on the Internet, and is the address of standard resources on the Internet. Each file on the internet has a unique URL that contains information indicating the location of the file and how the browser should handle it.

MD5: a widely used cryptographic hash function, called MD5 Message-Digest Algorithm, can generate a 128-bit (16-byte) hash value to ensure that the information transfer is complete and consistent. The digest algorithm is also called a hash algorithm or a hash algorithm. MD5 is a message digest encryption algorithm. It converts data of arbitrary length into a character string of fixed length by a fixed function.

Index encoding: base64 is an index code, one for each character.

AES encryption: the AES encryption algorithm is known as Advanced Encryption Standard (advanced encryption standard) and is one of the most common symmetric encryption algorithms. The basic requirement of AES is that with symmetric block cipher systems, the key length can be 128, 192 or 256 bits, the block length 128 bits, the algorithm should be easy to implement on various hardware and software.

Hash function: it is a mathematical equation that can use text (e.g., email messages) to generate a code called an abstract of information. Well known hash functions are: MD4, MD5, SHS. Hash operations accept an unlimited length input (input) and return a fixed length output (output).

In the present specification, the preset database and the preset link library refer to the memory mapping relationship, and only different writing methods are used for distinguishing.

In order to ensure the security of the URL link address during transmission. The application provides an encryption method of a shared link, which is applied to a server. FIG. 1 is a schematic flow chart of a method for encrypting a shared link according to an embodiment of the present application; referring to fig. 1, the method includes the following steps S101-S104.

Step S101: and receiving an encryption request sent by first user equipment, wherein the encryption request comprises a first network link to be shared, and the first user equipment is the user equipment to be shared.

In the above steps, a user corresponding to the first user equipment needs to share a network link of a certain page in the website based on own requirements, and the user sends the network link to the server by using the first user equipment to request the server to encrypt the network link; the server receives an encryption request sent by first user equipment, wherein the first user equipment comprises mobile phones, computers, tablets and other electronic equipment.

For example, when browsing a website, the user a finds that an article is good in the website and wants to share the article with friends, in order to ensure the security of the network link in the transmission process, the user a sends an encryption request to a server through a first user device, the encryption request includes a first network link corresponding to the article in the website, and the server receives the encryption request sent by the first user device and processes the first network link. The content specifically shared by the user is not limited herein, but is merely exemplary and is not further illustrated.

Step S102: and judging whether a mapping relation between the first network link and the second network link is prestored in a preset database, wherein the second network link is a network link for encrypting the first network link.

In the above step, the preset database is used for storing the mapping relation between the original network link and the encrypted network link, the original network link represents the network link address initially set by a certain page in the website, and the original network link is the first network link; the encrypted network link represents a network link address obtained by encrypting the original network link, and the encrypted network link is the second network link.

For example, the server obtains the first network link, and determines whether a mapping relationship between the first network link and the second network link is stored in the preset database in advance.

Step S103: when the mapping relation between the first network link and the second network link is stored in the preset database, inquiring the second network link corresponding to the first network link in the preset database.

In the above step, the server confirms that the preset database stores the mapping relationship between the first network link and the second network link; and inquiring a second network link corresponding to the first network link according to the mapping relation in a preset database. The mapping relationship means that after the first network link and the second network link are bound, the server can obtain the second network link through the first network link, and the server can also obtain the first network link through the second network link.

For example, the user a sends an encryption request to the server through the user device, the server confirms that the mapping relationship between the first network link and the second network link is stored in the preset database, and the server queries the second network link bound to the first network link.

Further, when the server confirms that the mapping relationship between the first network link and the second network link is not stored in the preset database, the server needs to reestablish the mapping relationship, acquire the first network link, establish the mapping relationship between the first network link and the second network link, and store the mapping relationship in the preset database.

For example, the user G sends an encryption request to the server through the user device, the server confirms that the mapping relationship between the first network link and the second network link is not stored in the preset database, the server obtains the first network link, establishes the mapping relationship between the first network link and the second network link, and stores the mapping relationship in the preset database.

Step S104: and sending the second network link to the first user equipment so that the first user equipment shares the second network link to the second user equipment, wherein the second user equipment is the user equipment for receiving the sharing.

In the step, the server inquires that the mapping relation between the first network link and the second network link exists in a preset database, and the server completes a first network link encryption request sent by the first user equipment; the server sends a second network link corresponding to the first network link to the first user equipment according to the mapping relation, the first user equipment can share the second network link with the second user equipment according to the self demand, and the second user equipment is user equipment such as friends, colleagues or relatives of the first user equipment. By adopting the method, the security of the network link in the transmission process can be ensured due to the encryption of the network link.

For example, a user S needs to share a certain website content to a user D, in order to ensure the security of the website content in the transmission process, the user S sends an encryption request to a server through a first user device by using a first network link corresponding to the website content, and the server processes the first network link according to the encryption request; binding the encrypted second network link with the first network link, wherein a mapping relation exists between the first network link and the second network link, the server sends the second network link to the first user equipment, the user S sends the second network link to the second user equipment through the first user equipment, and the person corresponding to the second user equipment is user D.

In one possible embodiment, how to establish the mapping relationship between the first network link and the second network link is described in fig. 2, and fig. 2 is a second flow diagram of an encryption method for sharing links according to the embodiment of the present application, where the method includes the following steps 201 to 205.

Step 201: and acquiring the first key and the first network link, and splicing the first network link and the first key to obtain a first result.

In the above step, the first key is any one randomly generated key; the first result is that the first network link and the first key are spliced according to a specified sequence. The length of the first network link may be 16384 characters, so that the length of the first network link cannot exceed 2038 characters for the convenience of user browsing, so that the length of the characters corresponding to the first network link is longer, and the specific order is mainly based on the data condition, which is not limited herein.

For example, the first network link is xxxxxx, the first key is yyyyy, and the first network link is spliced with the first key to obtain a first result D1, so d1=s1+key1, S1 represents the first network link, key1 represents the first key, and +represents the string splicing operator. The length of the specific first network link is mainly the actual situation, and the length of the specific first key is mainly the actual situation, which is only illustrated here.

Step 202: and carrying out hash operation on the first result to obtain a second result.

In the above steps, the first result is obtained by splicing the first network link and the first key, so that the length of the first result is greater than the original character length of the first network link, hash operation is performed on the first result, and the input of a character string with unlimited length is returned to the output of a character string with fixed length. The hash operation here refers to performing MD5 calculation, MD5 being a well-known hash function, and calculating a checksum of MD5 of the first result.

For example, the first result is D1, and there are 1500 characters in D1, the MD5 checksum of the first result is calculated, 20 characters in D2 are obtained, and 1500 characters in the first result are output with a fixed length.

Step 203: and splicing the second result and the first network link to obtain a third result.

In the above step, the second result is obtained by performing hash operation on the first result, and the second result is spliced with the first network link to obtain a third result.

For example, the number of characters of the second result D2 is fixed, the number of characters of the first network link cannot exceed 2038, the second result is spliced with the first network link, and a third result D3 is obtained, where the third result D3 is more than the characters of the first network link.

Step 204: and obtaining the second key, and performing AES encryption on the third result and the second key to obtain a fourth result.

In the step, the second secret key is any randomly generated secret key, and the third result is obtained by splicing the second result and the first network link; and carrying out AES encryption on the second key and the third result to obtain a fourth result, wherein the AES encryption also returns an input with an unlimited length to a fixed length for output.

For example, the third result has more than 2000 characters, the second key is kkkkkkkk, and AES encrypting the third result with the second key results in a fourth result, which is a fixed character. The number of specific characters is mainly actual, and is not limited here.

Step 205: and obtaining a second network link according to the fourth result, and establishing a mapping relation between the first network link and the second network link.

In the above step, when the fourth result is the second network link, a mapping relationship between the first network link and the second network link is established; since the fourth result is obtained by AES encrypting the third result with the second key, the fourth result contains complex and special characters such as a wave number, an exclamation mark, a dash, a comma, a percentile, and the like. In order to facilitate the second network link to be more convenient to propagate in the network, the fourth result is subjected to index coding, and the second network link obtained after coding is common characters, such as case English letters and numbers. For example, when the predetermined length of the character string of the second network link is 6, 26 uppercase or lowercase english letters are used, and the number of the second network links to the power of 6 is about 568 billions. The second network link may be generated as a combination of 26 uppercase english letters and lowercase english letters, and 10 digits. When an attacker wants to acquire the second network link, it takes a long time and cost to try to acquire the second network link one by one. After the second network link is acquired, the second network link is checked in a server storing the first network link, otherwise, the first network link corresponding to the second network link cannot be checked. The preset length is mainly the actual situation, and is not limited here.

For example, the fourth result has a predetermined character length of 6, fourth result setting is/-is, and carrying out index coding on the fourth result to obtain an aFLt2w, namely, the aFLt2w is a second network link.

Further, in the above steps, the step S204 and the step S202 may be exchanged, and the preset length of the fourth result obtained after the exchange is 20, and since the fourth result is obtained by AES encrypting the third result and the second key, the fourth result includes some complex and special characters, such as a wave number, an exclamation mark, a dash, a comma, a percentile, and the like. In order to facilitate the second network link to be more convenient in network propagation, the fourth result is index coded, and the second network link is obtained after coding. The specific preset length is mainly the actual situation and is not limited here.

By adopting the method, the length of the original network link address content can be shortened by only a few characters, the length is very short, and the transmission and the sharing between the user equipment are convenient. And the advantage of short network link is that save the flow, suitable for mobile internet application.

In a possible embodiment, how the second user equipment receives the second network link sent by the first user equipment and accesses the second network link is shown in fig. 3, and fig. 3 is a third flow diagram of a method for encrypting a shared link according to an embodiment of the present application, where the method includes the following steps 301 to 303.

Step S301: and receiving an access request sent by the second user equipment, wherein the access request comprises a second network link.

In the above steps, the first user equipment sends the second network link to the second user equipment through the third party platform, the second user equipment receives the second network link sent by the first user equipment, the user sends an access request of the second network link to the server through the second user equipment, and the server receives the access request of the second user equipment for sending the second network link.

Step S302: and inquiring a first network link corresponding to the second network link in a preset database.

In the above step, after receiving the second network link, the server queries the first network link corresponding to the second network link in the preset database according to the mapping relationship.

For example, the user K receives the second network link sent by the user W, the user K sends an access request of the second network link to the server through the second user device, the server receives the access request of the second network link, and queries the first network link corresponding to the second network link in the preset database.

Step S303: the first network link is sent to the second user device for the second user device to access the first network link.

In the above steps, after the server queries the first network link corresponding to the second network link, the server sends the first network link to the second user equipment, and the second user equipment accesses the website or other shared by the first user equipment by using the first network link.

For example, the second user device receives the first network link sent by the server, and queries the website corresponding to the first network link on the corresponding server, so that the user can check the website conveniently.

In a possible embodiment, the server receives a second encryption request sent by the first user equipment, where the second encryption request includes a fifth network link and a fourth user equipment identifier, and the fourth user equipment identifier refers to a unique identifier of the user, where the identifiers correspond to different situations; such as a website, a registered user name or account number, i.e., a logo; for example, bluetooth sharing, a user equipment name to be shared is input, and the user equipment name is an identifier; for example, a WeChat, namely a logo; the fourth user equipment is the user equipment to receive the share. The server establishes a mapping relation between a fifth network link and a sixth network link, and then stores the mapping relation in a preset database, wherein the sixth network link encrypts the fifth network link; and the server shares the sixth network link to the corresponding user equipment according to the fourth user identification, so that the fourth user equipment can conveniently access the sixth network link.

In one possible embodiment, the preset database comprises a relational database and a non-relational database, wherein the relational database comprises MySQL; KV database Memcache, REDIS, etc. The databases such as MySQL and MongoDB can establish unique indexes, have persistence capability, completely meet the requirement of CACHE-SYSTEM caching, and have the unique defect of inferior performance as KV databases.

This application is intended to cover any adaptations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.

In the above method, the encryption process of the network link is completed by the server, and the encryption process of the network link is completed and discussed below by the user equipment.

The application also provides an encryption method of the sharing link, which is applied to the first user equipment, and takes a webpage of the sharing website as an example, and at the moment, the first user equipment is electronic equipment such as a mobile phone, a computer, a tablet and the like used for a user. FIG. 6 is a fourth flowchart of an encryption method for sharing links according to an embodiment of the present disclosure; referring to fig. 6, the method includes the following steps S601 to S604.

Step S601: in response to an encryption operation by the user, the encryption operation includes a third network link to be shared.

In the above step, when the user browses a certain website page, the user wants to share the content of one page of the website to other users, the user copies the network link corresponding to the website, and the first user device processes the third network link according to the encryption operation of the user.

For example, when the user L browses the website, it finds that the content of one page in the website is related to the experiment studied by the user H during the time period, and the user L copies the network link of the page of the website on the first user device, and the first user device uploads the network link to the server for encryption based on the operation of the user, and the first user device processes the network link.

Step S602: and judging whether a mapping relation between the third network link and a fourth network link is prestored in a preset link library, wherein the fourth network link is a network link for encrypting the third network link.

In the above step, the preset link library stores a mapping relationship between an original network link and an encrypted network link, where the original network link represents a network link address initially set by a page in the website, and the original network link is a third network link; the encrypted network link represents a network link address obtained by encrypting the original network link, and the encrypted network link is a fourth network link.

For example, the first user equipment determines whether to pre-store the mapping relationship between the third network link and the fourth network link in the preset link library according to the third network link sent by the user.

Step S603: when the mapping relation between the third network link and the fourth network link is stored in the preset link library, inquiring the fourth network link corresponding to the third network link in the preset link library.

In the above step, the first user equipment confirms that the preset link library stores the mapping relation between the third network link and the fourth network link; and inquiring a fourth network link corresponding to the third network link according to the mapping relation in a preset link library. The mapping relationship means that after the third network link and the fourth network link are bound, the first user equipment can obtain the fourth network link through the third network link, and the server can also obtain the third network link through the fourth network link.

For example, based on the encryption operation of the user T on the third network link, the first user device confirms that the mapping relationship between the third network link and the fourth network link is stored in the preset link library, and queries the fourth network link bound with the third network link.

Further, when the mapping relation between the third network link and the fourth network link is not stored in the preset link library, the mapping relation between the third network link and the fourth network link is established in response to the third network link sent by the user; and storing the mapping relation in a preset link library.

The first user equipment, for example, based on the encryption operation of the user W on the third network link, confirms that the mapping relationship between the third network link and the fourth network link is not stored in the preset link library, establishes the mapping relationship between the third network link and the fourth network link based on the third network link sent by the user, and stores the mapping relationship in the preset link library.

Step S604: and responding to the sharing operation of the user, and sending the fourth network link to the third user equipment so as to facilitate the third user equipment to access the fourth network link.

In the above steps, the first user equipment queries that the mapping relation between the third network link and the fourth network link exists in the preset link library, and the first user equipment completes the encryption operation of the user; the first user equipment sends the fourth network link to the third user equipment according to the sharing operation of the user, so that the user corresponding to the third user equipment can access the fourth network link. By adopting the method, the security of the network link in the transmission process can be ensured due to the encryption of the network link.

For example, a user K needs to share a certain website content to a user J, in order to ensure the security of the website content in the transmission process, the user K copies a third network link corresponding to the website content, and sends an encryption operation to the first user device according to the operation of the user K; the first user equipment processes the third network link according to encryption operation, binds the encrypted fourth network link with the third network link, wherein the third network link and the fourth network link are in a mapping relation, and the first user equipment sends the fourth network link to a person J corresponding to the third user equipment according to sharing operation of a user.

In one possible embodiment, how to establish the mapping relationship between the third network link and the fourth network link is shown in fig. 7, and fig. 7 is a fifth flowchart of an encryption method for sharing links according to the embodiment of the present application, where the method includes the following steps 701 to 705.

Step 701: and acquiring the third key and the third network link, and splicing the third network link and the third key to obtain a fifth result.

In the above step, the third key is any one randomly generated key; the fifth result is that the third network link and the third key are spliced according to the specified sequence. The length of the third network link may be 16384 characters, so that the length of the third network link cannot exceed 2038 characters for the convenience of user browsing, so that the length of the characters corresponding to the third network link is longer, and the specific order is mainly based on the data condition, which is not limited herein.

For example, the third network link is yyyyyx, the third key is xxxxx, and the third network link is spliced with the third key to obtain a fifth result D5, so d5=s3+key3, S3 represents the third network link, key3 represents the third key, and +represents the string splicing operator. The length of the specific third network link is mainly the actual situation, and the length of the specific third key is mainly the actual situation, which is only exemplified here.

Step 702: and carrying out hash operation on the fifth result to obtain a sixth result.

In the above step, the fifth result is obtained by splicing the third network link and the third key, so that the length of the fifth result is longer than the original character length of the third network link, and the hash operation is performed on the fifth result, namely, the input of a character string with unlimited length is returned to the output of a character string with fixed length. The hash operation here refers to performing an MD5 calculation, where MD5 is a well-known hash function, and calculating an MD5 checksum of the first result.

For example, the fifth result is that there are 1450 characters in total in D5 and D5, the MD5 checksum of the fifth result is calculated to obtain 20 characters in total in the sixth result D6 and D6, and 1450 characters in the first result are output with a fixed length.

Step 703: and splicing the sixth result with the third network link to obtain a seventh result.

In the step, the sixth result is obtained by performing hash operation on the fifth result, and the sixth result is spliced with the third network link to obtain a seventh result.

For example, the number of characters of the sixth result D6 is fixed, the number of characters of the third network link cannot exceed 2038, and the sixth result is spliced with the third network link to obtain a seventh result D7, where the seventh result D7 is more than the characters of the third network link.

Step 704: and obtaining a fourth key, and performing AES encryption on the seventh result and the fourth key to obtain an eighth result.

In the step, the fourth secret key is any randomly generated secret key, and the seventh result is obtained by splicing the sixth result with the third network link; and carrying out AES encryption on the fourth key and the seventh result to obtain an eighth result, wherein the AES encryption also returns an input with an unlimited length to a fixed length for output.

For example, the seventh result has 1850 characters, the second key is llll, and AES encrypting the seventh result with the fourth key results in an eighth result, the eighth result being a fixed character. The number of specific characters is mainly actual, and is not limited here.

Step 705: and obtaining a fourth network link according to the eighth result, and establishing a mapping relation between the third network link and the fourth network link.

In the above step, when the eighth result is the fourth network link, a mapping relationship between the third network link and the fourth network link is established; since the eighth result is obtained by AES encrypting the seventh result and the fourth key, the eighth result includes complex and special characters such as a wave number, an exclamation mark, a dash, a comma, a percentile, and the like. In order to facilitate the fourth network link to be more convenient to propagate in the network, the eighth result is subjected to index coding, and the fourth network link obtained after coding is common characters, such as English letters and numbers with the upper and lower cases. For example, when the predetermined length of the character string of the fourth network link is 6, 26 uppercase or lowercase english letters are used, and the number of the fourth network link is about 568 billions to the power of 26 of 6. The fourth network link may be generated as a combination of 26 uppercase english letters and lowercase english letters, and 10 digits. When an attacker wants to acquire the fourth network link, it takes a long time and cost to try to acquire the fourth network link one by one. After the fourth network link is acquired, the server storing the third network link is required to check, otherwise, the third network link corresponding to the fourth network link cannot be checked. The preset length is mainly the actual situation, and is not limited here.

For example, the preset character length of the eighth result is 6, the fourth result is set as | t/-, and the eighth result is index-coded to obtain LtwaF2, which is the second network link of LtwaF 2.

Further, in the above steps, the step S604 and the step S602 may be exchanged, and the preset length of the eighth result obtained after the exchange is 20, and since the eighth result is obtained by AES encrypting the seventh result and the fourth key, the eighth result includes some complex and special characters, such as a wave number, an exclamation mark, a dash, a comma, a percentile, and the like. In order to facilitate the fourth network link to be more convenient in network propagation, the eighth result is index-coded, and the fourth network link is obtained after coding. The specific preset length is mainly the actual situation and is not limited here one by one.

By adopting the method, the original network link address content length can be changed into only a few characters, the length is very short, and the transmission and the sharing among the user equipment are convenient. And the advantage of short network link is that save the flow, suitable for mobile internet application.

In one possible embodiment, in response to an access request sent by the third user device, the access request includes a fourth network link; the first user equipment sends an access request of the fourth network link based on the user, and the user corresponds to the third user equipment. Inquiring a third network link corresponding to the fourth network link in a preset link library; after the first user equipment inquires a third network link corresponding to the fourth network link in a preset link library according to the mapping relation after the fourth network link is sent by the user. Transmitting the fourth network link to the third user device for the third user device to access the third network link; after the first user equipment inquires the third network connection corresponding to the fourth network link, the third user equipment accesses the website sent by the first user equipment according to the access operation of the user.

For example, according to the access operation of the user Y, the first user device queries the third network link corresponding to the fourth network link in the preset link library, and after querying the third network link corresponding to the fourth network link, the user queries the website corresponding to the third network link at the third user device.

In one possible embodiment, the preset database comprises a relational database and a non-relational database, wherein the relational database comprises MySQL; KV database Memcache, REDIS, etc. The databases such as MySQL and MongoDB can establish unique indexes, have persistence capability, completely meet the requirement of CACHE-SYSTEM caching, and have the unique defect of inferior performance as KV databases. Memcache belongs to a pure memory database, does not have persistence capability, is based on memory and has the fastest speed, but cannot meet the uniqueness requirement of CACHE-SYSTEM, and needs to be modified. The system uses REDI to cache one copy, and the database also stores one copy. The CACHE-SYSTEM buffer supports three operations, namely, storing the mapping relation between the third network link and the fourth network link, acquiring the mapped fourth network link according to the third network link, and acquiring the mapped third network link according to the fourth network link.

By adopting the method, the first user equipment encrypts the network link according to the encryption operation of the user, the obtained mapping relation is stored in the preset link library, and the encrypted network link is sent to the third user equipment according to the sharing operation of the user, so that the third user equipment can conveniently access the network link; because the network link is encrypted, the original network link is changed from a long link to an encrypted network link short link, the difficulty of restoring the encrypted network link to the original network link is high, the restoring process is very complex, the original network link can be obtained only through a mapping relation, the changing process is irreversible with high probability, the transmission flow is saved by using the short link, and the method is suitable for mobile Internet application and can ensure the safety of the network link in the transmission process.
