It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that the terms "first," "second," and the like, as used herein, may be used to describe various elements, but these elements are not limited by these terms unless otherwise specified. These terms are only used to distinguish one element from another element. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script, without departing from the scope of the present application.
The inventors found in practice that factors affecting the anti-fouling ability of groundwater in a karst region are many, for example, the more indexes are used in the anti-fouling function evaluation such as karst pipeline development conditions, rainfall infiltration conditions, protection layer characteristics, etc., the larger the corresponding data processing amount is, the problem of large data processing amount can be solved by transmitting data including investigation data and analysis programs from a personal computer to a server, but there is a risk of data leakage when transmitting data to the server.
Aiming at the risk of data leakage when data are transmitted to a server, the invention firstly provides a karst fracture network type aqueous medium antifouling function evaluation method shown in figure 1, which is realized by executing the following steps:
dividing the transmission data into different transmission data blocks by a client for storage, randomly determining a plurality of data blocks therein, generating first transmission information by the client according to the determined data blocks, wherein the first transmission information also comprises an identifier for carrying out security authentication on a receiving server, and transmitting the first transmission information to the receiving server by the client;
step two, when the receiving server receives the first sending information from the client, the receiving server takes out the determined data block from the first sending information and stores the data block, and meanwhile, the receiving server carries out conversion processing on the determined data block according to the identification of the receiving server for security authentication by the client in the first sending information so as to generate security authentication information;
step three, the client judges whether the safety authentication information from the receiving server is received within a preset time after the first sending information is sent out, if the safety authentication information is not received, the client judges that the data transmission between the client and the receiving server is unsafe, if the safety authentication information is received, the client carries out recovery processing on the safety authentication information to extract a determined data block, verifies the consistency of the extracted determined data block and the self-stored determined data block, when the extracted determined data block and the self-stored determined data block are consistent, the client uses the self-stored determined data block to encrypt other self-stored data blocks, and simultaneously sends second sending information comprising an encryption processing result to the receiving server, and when the extracted data block and the self-stored data block are inconsistent, the client judges that the data transmission between the client and the receiving server is unsafe;
and step four, the receiving server uses the determined data block stored by the receiving server to decrypt the encryption processing result in the second sending information to obtain other data blocks, and processes the determined data block stored by the receiving server and the other data blocks in a combined way.
Specifically, in the first step, the client divides the transmission data into a plurality of data blocks to be stored, and generates the first transmission information to be transmitted to the receiving server, the first transmission information includes a plurality of randomly determined data blocks, and the client and the receiving server agree in advance on an identifier by which the client decides to verify the identity of the receiving server, in the second step, the receiving server receives the determined data blocks transmitted by the client, and converts the determined data blocks according to the identifier to generate security authentication information, in the third step, the client always judges whether the security authentication information is received after the first transmission information is transmitted, if the security authentication information is not received for a certain period of time, then the data transmission with the receiving server is considered to be unsafe, and the receiving server is refused to be illegally attacked by the receiving server, or a network problem between them, if the security authentication information is received, the receiving server recovers the security authentication information according to the identifier selected before it, and processes the recovered data blocks and the same as the data blocks before the data blocks are not received by the receiving server, and if the data blocks are determined to be further encrypted by the receiving server, and the key is further considered to be encrypted, in order to further ensure that the key is transmitted between the receiving server and the other steps, and the key is further encrypted if the data is not determined to be transmitted, and the receiving server uses the previously stored determined data blocks to decrypt the encryption processing result of the client so as to obtain other data blocks, and finally, the receiving server performs combination processing with the previously stored determined data blocks. Through the first step to the fourth step, the client will not send the complete sending data to the receiving server before determining that the data transmission with the receiving server is safe, so that the sending data can be prevented from being leaked.
Further, the receiving server performs conversion processing on the determined data block, including encrypting the determined data block using a symmetric encryption key, and including encrypting the determined data block using a private key thereof;
further, the client performs recovery processing on the security authentication information, including decrypting the security authentication information using a symmetric decryption key, and including decrypting the security authentication information using a public key of the receiving server.
Specifically, when generating the first transmission information sent to the receiving server, the client determines an identifier for performing security authentication on the receiving server, different identifiers represent different security authentication modes, the receiving server can complete authentication on own identity according to the identifier, if the receiving server uses a symmetric encryption key to encrypt a determined data block according to the identifier, the client uses the symmetric decryption key to decrypt the security authentication information, if the receiving server uses an own private key to encrypt the determined data block according to the identifier, the client uses a public key of the receiving server to decrypt the security authentication information, wherein the symmetric encryption key and the private key of the receiving server only are owned by the receiving server.
Further, the process that the client divides the transmission data into different transmission data blocks to store, and randomly determines a plurality of data blocks therein may further include that firstly the transmission data is represented in a binary form, and a hash value of the binary transmission data is calculated, secondly the original transmission data is covered by the result data of binary multiplication operation performed by using the hash value and the binary transmission data, and finally the present transmission data is divided into different transmission data blocks, and a plurality of transmission data blocks are randomly determined in the different transmission data blocks.
In particular, in the first step, the transmission data is directly divided into a plurality of different transmission data blocks, so that a plurality of data blocks are determined in the plurality of different transmission data blocks, which has the advantages of being convenient and fast, and the disadvantage of lacking the transformation processing for the transmission data, when an illegal third party which is an impossibility of a receiving server has acquired the determined data blocks transmitted by a client, there may be a risk that the illegal third party presumes the meaning of the determined data blocks or is complete transmission data based on the determined data blocks, so that the invention also proposes that the transformation processing can be performed on the transmission data before dividing the transmission data, namely, the hash value of the binary original transmission data is calculated, so that the hash value and the binary original transmission data are calculated, and the binary original transmission data is replaced by the result data.
Further, the inventor also found that in the method described in the first step to the fourth step, the client always stores the complete transmission data, if the client is attacked illegally, the transmission data is likely to be leaked, and in the case that the communication distance between the client and the receiving server is far, a long transmission time is required from the client to the receiving server, and the risk of data leakage is increased, so the invention further proposes the following steps to solve the technical problems on the basis of transforming the original transmission data:
step one, the client generates first sending information, wherein the first sending information comprises a determined data block and a target address of the determined data block, and the client sends the first sending information to a first server, and meanwhile deletes the determined data block stored by the client and only stores the rest other data blocks and the hash value; the first server receives first sending information from the client, stores the determined data block and the target address of the determined data block according to the first sending information, sets a storage validity period, and sends first notification information comprising the storage address and the storage validity period back to the client;
step two, the client receives and stores the first notification information, and sends second sending information comprising other data blocks to a second server; when the second server receives the second transmission information, extracting other data blocks from the second transmission information and storing the data blocks, and simultaneously transmitting second notification information to the client, wherein the second notification information comprises the address of the second server;
step three, the client compares the address of the second server included in the second notification information with the target address stored by the client, and when the address of the second server and the target address are consistent, the client transmits third transmission information including the storage address of the determined data block to the second server; the second server sends third notification information to the first server according to a storage address in the third sending information, wherein the third notification information comprises the address of the second server;
step four, the first server verifies whether the address of the second server in the third notification information is the same as the self-stored target address, if so, the first server sends the self-stored determined data block to the second server when the storage validity period is in the storage validity period, and meanwhile, the first server sends fourth sending information to the client; after receiving the fourth transmission information, the client transmits fourth known information including the hash value stored in the client to the second server; the second server processes the determined data block and other data blocks in combination, and performs binary division operation using the result data of the combination processing and the hash value.
Specifically, in the above step one, the client generates first transmission information to be transmitted to the first server based on the determined transmission data block obtained after the conversion processing of the original transmission data, the first transmission information further includes a destination address of the determined transmission data block, while the client deletes the determined transmission data block stored by itself, the client at this time no longer stores the entire transmission data, when the first server receives the first transmission information, stores the determined transmission data block, and the corresponding destination address, further sets a validity period for the stored contents, exceeding the validity period, and includes the stored address and the validity period in the first notification information, in the above step two, the client receives and stores the content of the first notification information while generating second transmission information to be transmitted to the second server using the remaining other data blocks, it is noted that the above first server is interposed between the client and the second server at a communication distance, the second server stores the second transmission information block in accordance with the client before the first transmission information, and sets the validity period for the stored contents, and when the second server receives the second transmission information, and the second transmission information is not included in the second notification information, the client is not included in the second notification information, and the second transmission information is not included in the second notification information, the second transmission information is stored in the second notification information, and the second transmission information is not included in the second notification information, and the second transmission information is stored in the second notification information, and the second transmission information is not included in the second transmission information, and the second transmission information is stored in the second transmission information, and the second transmission information is sent to the second transmission information, and the second transmission information is used, therefore, after the second server receives the third transmission information, the second server can send third notification information to the first server according to the storage address to verify the identity of the second server, the third notification information comprises the address of the second server, in the fourth step, the first server checks whether the address of the second server in the third notification information is identical to the target address stored by the second server, when the address of the second server is different from the target address stored by the second server, the first server considers that the data transmission with the second server is unsafe, when the address of the second server is identical to the target address, the first server further checks whether the data transmission with the second server is unsafe, if the data transmission with the second server is not, the data transmission with the second server is still considered unsafe, the second server is refused to send a determined data block to the second server, when the second server possibly suffers illegal attack, the second server reduces the possibility that the illegal third party is illegal to act as the second server, if the address is different from the second server, the fourth transmission information is sent to the client, the client knows that the second server is safe when the second server is received, the second server is safe, the data transmission with the second server is safe, the second server is stored in the second server, the second server is safe, the data is the second data is stored in the second server, the second data is the second server, and the second data is different from the first data.
By the method described above, the client and the first server always store only a part of the transmitted data, so that even if the client and the first server are illegally attacked, data leakage cannot be caused, in addition, before the client and the first server pass multiple security authentications, the second server cannot have complete data, and only when the client and the first server pass the authentication, the second server can have complete data, so that the data cannot be leaked.
Further, the data amount of the determined data block in the first transmission information sent to the first server by the client is larger than the data amount of the other data block in the second transmission information sent to the second server by the client. Specifically, the single communication distance between the first server and the second server is smaller than the single communication distance between the client and the second server, so that the first server sends the determined data block to the second server, the total communication distance between the client and the second server can be shortened, the data transmission time between the client and the second server is shortened, the data volume of the determined data block is set to be larger than the data volume of other data blocks, and the data transmission time can be further shortened.
