Embodiment
At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
During Webpage that the user terminal access webserver provides, can be linked to corresponding server, and then obtain data resource, for example displaying video, audio frequency, data download etc. by obtaining domain name link embedded in this Webpage.Because a lot of data resources have authority, if domain name link is stolen, might cause the abuse of data resource.In order to solve the problem that prior art exists, the embodiment of the invention provides a kind of method of verifying the domain name link, and as shown in Figure 1, this method may further comprise the steps:
Concrete, user terminal obtains embedded domain name link in the Webpage that the webserver provides, and perhaps from the domain name link of other relevant acquisitions, this domain name link can comprise marking head, timestamp, checking enciphered message and domain name.Wherein, marking head is antitheft domain name link for this domain name link of sign; Timestamp is used for the time that sign produces this domain name link; Checking secret value information is obtained by the common key string of web page server according to this timestamp, domain name and regular update, can be the forms such as value or character string; Domain name is the domain name of user terminal wish access.Wherein, web page server regularly upgrades the common key string, and the common key string after will upgrading is synchronized in the name server, thus, serially add the checking enciphered message regular update of close acquisition by this common key, and then comprise the embedded domain name link regular update of Webpage of this checking secret value.Like this, after the domain name link is updated, stolen before domain name link can't be used.
After name server receives the request of carrying domain name link of user terminal transmission, at first judge by marking head whether this domain name link is antitheft domain name link, for example: using QQQQ is the marking head of antitheft domain name link, if the marking head of this domain name link is not QQQQ, then not antitheft domain name link, directly send IP address corresponding to this domain name link to this user terminal; If marking head is QQQQ, then be antitheft link, need further whether this domain name link of checking is legal.For example, checking enciphered message and Standard Encryption information that name server obtains in this domain name link are compared, if coupling, then this domain name is linked as the legitimate domain name link; If do not match, then this domain name is linked as illegal domain name link, does not allow the visit of user terminal.
Wherein, this Standard Encryption information is that name server obtains according to the timestamp in this domain name link, domain name and pre-stored common key string, can be the forms such as value or character string.The webserver is stored respectively identical common key string with name server, and upgrades this common key string with cloth, and for example, the webserver and name server are stored respectively password string abcdef, and with cloth this password string is being updated to 1234567.And it is identical with the mode of Standard Encryption information to obtain this checking enciphered message, as using md5 encryption algorithm etc.
Not only can be by the mode that will verify that enciphered message and Standard Encryption information are compared, whether the authentication enciphered message is legal, can also use other modes to verify, after for example the checking enciphered message can being decrypted, extract the character in precalculated position, whether form character string, it is legal to encrypt this character string and validator then.
If step 102 the result is legal, judge whether this domain name link is in effective life;
If the result is legal, as the comparison result of verifying enciphered message and Standard Encryption information is coupling, name server obtains the domain name link generation time of the timestamp sign that this domain name link carries, verify then the service time that obtains according to this domain name link generation time, whether in predetermined effective life.Can be this domain name link generation time service time, also can be the time that this domain name link generation time obtains by conversion.For example, timestamp is 123456, the domain name link generation time of its sign is on 09 11st, 2010 12:00, predetermined effective life is on 09 11st, 2010 6:00 to 14:00, because 12:00 is positioned at this time period of 6:00 to 14:00, can determine that then this domain name link was in effective life, was effectively domain name link; Perhaps timestamp is 123456, the domain name link generation time of its sign is XX XX month XX day 12:00, it is XX XX month XX day 12:30 by the service time that conversion obtains, predetermined effective life is XX XX month XX day 6:00 to 12:00, because 12:30 is not positioned at this time period of 6:00 to 12:00, can determine that then this domain name link was not in effective life, be invalid domain name link; Perhaps timestamp is 123456, the domain name link generation time of its sign is XX XX month XX day 12:00, current time is XX XX month XX day 16:00, both time differences are 4 hours, because effective life is 6 hours, therefore this domain name link was in effective life, was effectively domain name link; The domain name link generation time of perhaps supposing its sign is 10:00 on September 13rd, 2010, obtaining service time by predetermined conversion process (as addition subtraction multiplication and division etc.) again is 12:00 on September 13rd, 2010, predetermined effective life is 17:00 on the 13rd in September 6:00 to 2010 year on the 11st September in 2010, can determine that then this domain name link was in effective life, was effectively domain name link.
Wherein, when checking enciphered message and Standard Encryption information matches, both are identical, perhaps meet predetermined corresponding relation, for example hypothesis verification enciphered message and Standard Encryption information all are A, and perhaps Yu Ding corresponding relation is that A is B corresponding to Standard Encryption information for the checking enciphered message.
If this domain name link of step 103 was in effective life, confirm that domain name link is effective domain name link.After name server confirms that domain name link is effective domain name link, according to the domain name in this domain name link, search and return IP address corresponding to this domain name link to this user terminal, so that user terminal obtains corresponding data resource according to this IP address access server.
Pass through foregoing description, as can be seen, the method that the domain name link of using the embodiment of the invention to provide is verified, by in web page server, domain name link being encrypted and setting-up time stabs, in name server, legal checking and validity verification are carried out in this domain name link simultaneously, prevent to use stolen domain name link to obtain data resource with this.And this secret value of regular update shortens stolen domain name as far as possible and links the spendable time, has prevented effectively that to a certain extent the domain name link is stolen.
The method of the domain name link checking that the embodiment of the invention is provided below by specific embodiment is elaborated, and as shown in Figure 2, specifically may further comprise the steps:
The webpage that step 201, user terminal access web page server provide;
After step 204, name server receive this request, obtain marking head in this domain name link, judge whether to be antitheft domain name link; If antitheft domain name link then continues execution in step 205; Otherwise, execution in step 208; Wherein QQQQQ is the marking head of the antitheft domain name link of expression.
Because name server uses identical AES with web page server, use identical parameter, obtain respectively Standard Encryption information and checking enciphered message, if checking enciphered message and Standard Encryption information matches, illustrate that then this domain name link is legal domain name link, otherwise, be illegal domain name link.Wherein, when checking enciphered message and Standard Encryption information matches, both are identical, perhaps meet predetermined corresponding relation, for example hypothesis verification enciphered message and Standard Encryption information all are A, and perhaps Yu Ding corresponding relation is that A is B corresponding to Standard Encryption information for the checking enciphered message.
Concrete, timestamp is 1263175145, the domain name link generation time of supposing its sign is 16:00 on September 12nd, 2010, predetermined effective life is 17:00 on the 12nd in September 6:00 to 2010 year on the 11st September in 2010, can determine that then this domain name link was in effective life, was effectively domain name link; The domain name link generation time of perhaps supposing its sign is 16:00 on September 13rd, 2010, predetermined effective life is 17:00 on the 12nd in September 6:00 to 2010 year on the 11st September in 2010, can determine that then this domain name link was not in effective life, be invalid domain name link; The domain name link generation time of perhaps supposing its sign is 10:00 on September 13rd, 2010, current time is 15:00 on September 13rd, 2010, and the time difference is 5 hours, less than pre-timing difference maximum (as 7 hours), can determine that then this domain name link was in effective life, was effectively domain name link; The domain name link generation time of perhaps supposing its sign is 10:00 on September 13rd, 2010, obtaining service time by predetermined conversion process (as addition subtraction multiplication and division etc.) again is 12:00 on September 13rd, 2010, predetermined effective life is 17:00 on the 13rd in September 6:00 to 2010 year on the 11st September in 2010, determine that then this domain name link was in effective life, was effectively domain name link.
