Embodiment
A kind of information processing method is provided in the embodiment of the present invention, has been applied to an electronic equipment, described method can comprise the acquisition first information, and the described first information is the information that contains domain name to be resolved; Control described electronic equipment and send the domain name mapping request for the described first information to domain name system DNS server, obtain the first Internet protocol IP address corresponding with the described first information that described dns server returns; Wherein, a described IP address is that described dns server is resolved and obtained according to the domain name that the described first information is comprised; A described IP address is mated with the 2nd IP address of acquisition, obtain a matching result; Wherein, described the 2nd IP address is the IP address corresponding with the described first information of presetting; According to described matching result, determine whether described dns server is held as a hostage.
In the embodiment of the present invention, because the described first information is to there being default described a 2nd IP address, therefore, in the time that described electronic equipment obtains the described first information, it is by sending the domain name mapping request corresponding with the described first information to dns server, can obtain a described IP address corresponding with this domain name, such as, in the time will carrying out website visiting, conventionally, user can be connected with described dns server by household radio router, to obtain a described IP address of being returned by described dns server, if a described IP address is identical with default described the 2nd IP address, the match is successful, determine that a described IP address is corresponding with the described first information, the domain name mapping address of safety, be that described dns server is kidnapped, thereby can access normally this website, if a described IP address and described the 2nd IP matching addresses are unsuccessful, illustrate that wireless router DNS is likely kidnapped, according to described matching result, described electronic equipment can determine whether described dns server is kidnapped, thereby can take corresponding prompting or measure, for example eject warning window, or utilize special anti-virus tool to carry out killing etc., prevent that hacker from distorting the malice of wireless router DNS, thereby ensure the fail safe of network.
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
In the embodiment of the present invention, described electronic equipment can be PC(personal computer), notebook, PAD(panel computer), the different electronic equipment of mobile phone etc., the present invention is not restricted this.
In addition, term "and/or" herein, is only a kind of incidence relation of describing affiliated partner, and expression can exist three kinds of relations, and for example, A and/or B, can represent: individualism A exists A and B, these three kinds of situations of individualism B simultaneously.In addition, character "/" herein, generally represents that forward-backward correlation is to liking a kind of relation of "or".
Refer to Fig. 1, the information processing method in the embodiment of the present invention can be applied to electronic equipment, and the main flow process of described method is as follows:
Step 101: obtain the first information, the described first information is the information that contains domain name to be resolved.
At present, network is in the time distinguishing all networks that are attached thereto and main frame, all adopt a kind of unique, general address format, be that each computer being connected with network and server have been assigned with a unique IP address, in order to guarantee the uniqueness of IP address of every computer on network, user must apply for the registration of to particular organization, and this particular organization is corresponding computer distributing IP address.
Address scheme in network is probably divided into two covers: IP address system and domain name addresses system.This two covers address system is relation one to one in fact.IP address represents with binary number, and long 32 bits in each IP address are less than 256 numeral and form by 4, and between numeral, with a some interval, for example 100.10.0.1 represents an IP address.Because IP address is Digital ID, when use, be difficult to memory and write, therefore on the basis of IP address, develop again a kind of address scheme of symbolism, replace the IP address of numeric type, be domain name (Domain Name), the title that it refers to a certain computer on the Internet of a string name composition of separating with point or calculates unit, because the address of each symbolism is corresponding with specific IP address, resource access on network gets up just much easier like this, the character type address that this is corresponding with numeric type IP address on network, is just called as domain name.QQ(immediate communication tool that for example we often see) domain name of website is www.qq.com, or be www.qzone.qq.com, etc.
And domain name mapping refers to that a domain name (being the network address) corresponds to the network address that real computer can be identified, i.e. IP address, such as the such form of 216.239.53.99, so that computer can further be communicated by letter, transmits network address and content etc.
In the embodiment of the present invention, the mode that obtains the described first information can be that the input operation by user obtains, for example in user's webpage clicking for entering the chained address of related web site, described electronic equipment can obtain the described first information.
Wherein, the domain name described to be resolved that the described first information comprises can refer to website domain name corresponding to website that user is about to conduct interviews, for example www.taobao.com.If this website is conducted interviews and needs the IP address of knowing that this website domain name is corresponding, need this website domain name to resolve.
Step 102: control described electronic equipment and send the domain name mapping request for the described first information to domain name system DNS server, obtain the IP address corresponding with the described first information that described dns server returns; Wherein, a described IP address is that described dns server is resolved and obtained according to the domain name that the described first information is comprised.
In the embodiment of the present invention, when described electronic equipment obtains after the described first information, the domain name mapping request corresponding with the described first information can be sent to described dns server.As a rule, first described electronic equipment can pass through WLAN(Wireless Local Area Networks, WLAN (wireless local area network)) domain name analysis request is sent to the wireless router of connection, and by described wireless router, domain name analysis request is sent to described dns server, parse according to domain name analysis request at described dns server behind a corresponding described IP address, this IP address is sent to wireless router, by described wireless router, a described IP address is returned to described electronic equipment again, so that described electronic equipment can be according to a described IP address access websites.
Preferably, in the embodiment of the present invention, a described IP address can refer to the IP address after the parsing obtaining by wireless router DNS.Conventionally, wireless router DNS can be sent to described dns server by domain name analysis request quickly and carries out domain name mapping.And, some network insertion business, such as Beijing Telecom, Shanghai Telecom etc., open the speed of webpage in order to accelerate user, conventionally in their dns server buffer memory the DNS record of a lot of domain names, in the time that a certain network insertion business's user will open certain webpage, this network insertion business's dns server does not need nslookup database like this, and the DNS record in own buffer memory directly can be used, thereby accelerate resolution speed, also the corresponding speed of accelerating user's access websites.
Step 103: a described IP address is mated with the 2nd IP address of acquisition, obtain a matching result; Wherein, described the 2nd IP address is the IP address corresponding with the described first information of presetting.
In the embodiment of the present invention, obtaining behind a described IP address, can a more described IP address whether identical with described the 2nd IP address, mate with described the 2nd IP address by a described IP address, thereby can obtain described matching result.
In the embodiment of the present invention, a described IP address is mated with the 2nd IP address of acquisition, there are two kinds of possible modes, wherein first kind of way can be: described electronic equipment has a default IP address table, the inquiry described two IP address corresponding with the described first information in described default IP address table; A described IP address is mated with described the 2nd IP address.
Preferably, in the embodiment of the present invention, described default IP address table can refer to a list that includes the IP address of conventional website domain name and correspondence thereof, for example, can be white list.Described white list can be collected and provided by special domain name registration service organization, and described electronic equipment can obtain by network, to set it as the default IP address table that self can inquire about.And the described default IP address table that described electronic equipment can also be regular or irregular renewal has, to guarantee accuracy and the integrality of described default IP address table, prevent because the modification of some website domain name or corresponding IP address causes accessing the most satisfied website.For example, the replacing of domain name IP address.
As a rule, the IP address corresponding with website domain name existing in described default IP address table is comparatively stable, the frequency changing is lower, therefore, can think that described the 2nd IP address inquiring is exactly corresponding with domain name to be resolved, IP address accurately in described default IP address table.Therefore, obtaining behind a described IP address and described the 2nd IP address, can directly a described IP address be mated with described the 2nd IP address, can know that whether both are identical.In addition,, because described default IP address table has been present in described electronic equipment, the process of inquiring about according to domain name is comparatively simple, quick, has stronger real-time.
Preferably, in the embodiment of the present invention, the inquiry described two IP address corresponding with the described first information in described default IP address table, specifically can comprise: judge in described default IP address table, whether there be the described two IP address corresponding with the described first information; In the time there is not the described two IP address corresponding with the described first information in described default IP address table, control described electronic equipment and upgrade described default IP address table, so that there is the described two IP address corresponding with the described first information in described default IP address table.
Obtaining in the process of described the 2nd IP address, by the judgement to described default IP address table, can determine whether to upgrade described default IP address, inquire about so that described default IP address table can provide compared with the IP address of horn of plenty.For example, in the time not existing with corresponding described the 2nd IP address of domain name to be resolved in the described first information in described default IP address table, described in needing to upgrade, establish IP address table, thereby can avoid again needing to determine the IP address corresponding with the described first information time, in described default IP address table, still search the situation less than corresponding IP address.
In the embodiment of the present invention, described default IP address table can refer to the corresponding lists of the IP address that records some websites domain name.For example, wherein can comprise: one of them website domain name is s.taobao.com, its corresponding IP address is 42.156.210.6, and wherein another website domain name is www.icbc.com.cn, and its corresponding IP address is 220.181.64.180, etc.And described electronic equipment can upgrade described default IP address table by background update system.
Preferably, in the embodiment of the present invention, the described default IP address table upgrading can be the up-to-date domain name that obtains by domain name registration service organization of described electronic equipment and the corresponding table of IP address, so that the described default IP address table after renewal can provide IP address lookup function for the domain name of new registration.
In the embodiment of the present invention, in first kind of way, in described electronic equipment, there is described default IP address table, therefore in the time needing to determine the IP address corresponding with domain name, can search corresponding IP address rapidly in described default IP address table, and it is mated with a described IP address, owing to searching and comparatively simple and fast of matching process, and required time is shorter, there is stronger real-time, the network that affects hardly user is experienced.
Meanwhile, as a rule, the frequency that changes IP address corresponding to website domain name is lower, therefore the corresponding relation of the website domain name recording in described default IP address table and IP address is comparatively stable.Therefore, by a described IP address is mated with described the 2nd IP address inquiring from described default IP address table, can determine whether a described IP address of being returned by described dns server is personation address, thereby avoid using the IP address being maliciously tampered, improved the fail safe of access to netwoks.
Preferably, in the embodiment of the present invention, the second way that a described IP address is mated with the 2nd IP address of acquisition can be: control described electronic equipment and send domain name analysis request by the second default network to described dns server; Obtain the described two IP address corresponding with the described first information that described dns server returns; A described IP address is mated with described the 2nd IP address, obtain described matching result.
Send domain name analysis request at described electronic equipment to described dns server, obtain a described IP address before, simultaneously or afterwards, described electronic equipment is also sent to described dns server by the described second default network by domain name analysis request, and obtain the described two IP address corresponding with the described first information that parse according to domain name analysis request, the wherein said second default network can be the network that described electronic equipment is connected with described dns server, for example 3G (Third Generation) Moblie technology (3rd-Generation, 3G) network, the 4th generation mechanics of communication (the4Generation mobile communication technology, 4G) network.In the time that described electronic equipment is sent to described dns server by the described second default network by domain name analysis request, described dns server can parse the described two IP address corresponding with the described first information according to domain name analysis request.Now, can think that described the 2nd IP address obtaining by the described second default network is corresponding with domain name to be resolved, unique IP accurately address.
Step 104: according to described matching result, determine whether described dns server is held as a hostage.
In the embodiment of the present invention, Domain Hijacking is a kind of mode that the Internet is attacked, and by attacking dns server, or forges the method for dns server, targeted website domain name mapping is reached to wrong address cannot access destination website object.For example, in the time that user's network meets with the situation that dns server is held as a hostage, some particular web site can cannot be opened, and even access the address of A website, and what open is but the page of B website.Implement fishing if hacker utilizes dns server to be held as a hostage, even if access is correct Net silver or shopping website address, also can enter the fishing website of hacker's personation.
In the embodiment of the present invention, if a described IP address is mated with described the 2nd IP address by first kind of way, according to described matching result, determine whether described DNS is held as a hostage, can comprise: when described matching result shows that a described IP address and described the 2nd IP matching addresses are when unsuccessful, domain name analysis request is sent to described dns server by the first default network, receives the three IP address corresponding with the described first information that described dns server returns; Judge that whether described the 3rd IP address is identical with described the 2nd IP address, obtain a judged result; Determine according to described judged result whether described DNS is held as a hostage.
, in embodiments of the present invention, if a described IP address with by inquiring about described the 2nd IP address that described default IP address table determines while not mating, can domain name analysis request be sent to described dns server by the described first default network, to obtain more accurately, the IP address corresponding with the described first information, it is described the 3rd IP address, and by being made comparisons in described the 2nd IP address and described the 3rd IP address, can judge whether described the 2nd IP address corresponding with domain name to be resolved in described default IP address table is up-to-date IP address, to guarantee that a described IP address can be corresponding with the described first information, mate unique correct IP address, improve the accuracy of matching process.
Preferably, in the embodiment of the present invention, the described first default network can be the network identical with the described second default network, for example, be all 3G/4G network.
Because described electronic equipment can connect by dns server by the described first default network, can think thus, described the 3rd IP address obtaining by the described first default network be the current and described first information corresponding, unique IP accurately address.
In the embodiment of the present invention, determine that according to described judged result whether described dns server is held as a hostage, and can comprise: when described judged result shows that described the 3rd IP address is with described the 2nd IP address when identical, determine that described dns server is held as a hostage; When showing described the 3rd IP address, described judged result when not identical, determines according to preset rules whether described DNS is held as a hostage with described the 2nd IP address.
; in the invention process; when a described IP address and described the 2nd IP matching addresses are when unsuccessful; described the 2nd IP address and described the 3rd IP address obtaining by the described first default network can be compared; if determine that described the 2nd IP address is identical with described the 3rd IP address, show that described default IP address table can provide IP address accurately for domain-name information.
For example, in the time that user uses the website of the mobile phone browser access Industrial and Commercial Bank of China, the domain name to be resolved that the described first information comprises is www.icbc.com.cn, it is 192.168.1.2 that described electronic equipment obtains a described IP address corresponding with this domain name by wireless router DNS, and described the 2nd IP address inquiring by described default IP address table is 220.181.64.180, therefore a described IP address and described the 2nd IP matching addresses are unsuccessful.Now, can control mobile phone and send identical domain name analysis request by 3G network to dns server, the IP address after the parsing obtaining is 220.181.64.180, i.e. described the 3rd IP address.Known by judging, described the 2nd IP address is identical with described the 3rd IP address, therefore can determine that described the 2nd IP address that described default IP address table provides is the accurate IP address of resolving after this domain name.
Preferably, in the embodiment of the present invention, if it is not identical with described the 2nd IP address that described judged result shows described the 3rd IP address, determine that according to preset rules whether described dns server is held as a hostage, and is specifically as follows: judge that whether described the 3rd IP address is consistent with a described IP address; If described the 3rd IP address and a described IP address are inconsistent, determine that described dns server is held as a hostage, otherwise, determine that described dns server is not held as a hostage.
In the embodiment of the present invention, when described the 3rd IP address is with described the 2nd IP address when not identical, known, in described electronic equipment, may there is inaccurate situation in the IP address corresponding with the described first information that current default IP address table provides.For example, described electronic equipment does not also upgrade described default IP address table.Now, can continue to judge that whether a described IP address is identical with described the 3rd IP address, thereby further determine whether described dns server is held as a hostage.
Preferably, in the embodiment of the present invention, if definite described dns server is held as a hostage, can controls described electronic equipment and carry out killing order or export corresponding warning message, prompting user's current accessed website is dangerous.
In the embodiment of the present invention, when described judged result shows that described the 3rd IP address is with described the 2nd IP address when not identical, described method can also comprise: control described electronic equipment described the 2nd IP address in described default IP address table is updated to described the 3rd IP address.
As a rule, described electronic equipment can be connected to normal dns server by network, and the acquisition parse addresses corresponding with domain name.Therefore, in the time that described electronic equipment sends domain name analysis request by default network to dns server, the parse addresses being returned by described dns server of acquisition, described the 3rd IP address is the IP address that the current and described first information is corresponding.Therefore, obtaining behind described the 3rd IP address, described the 2nd IP address corresponding with the described first information in current described default IP address table can be updated to described the 3rd IP address, thereby obtain the described default IP address table after upgrading, to provide corresponding IP address according to the described first information for domain name to be resolved.
Refer to Fig. 2, based on same inventive concept, the present invention also provides a kind of electronic equipment, and described electronic equipment can comprise acquisition module 201, operational module 202, matching module 203 and determination module 204.
