Abstract
The invention discloses an internet dual-dynamic-password subscriber identity authentication method and an internet dual-dynamic-password subscriber identity authentication system. The method comprises the following steps that: a server generates two dynamic passwords A and B and sends A and B respectively to a client and receiving equipment subscribed by a subscriber through a heterogeneous network; the client respectively combines the dynamic passwords A and B, service information and identity information of the subscriber for performing digital signature and passes a signature result back to the server; and the server performs the signature which is the same as that of the client, compares the signature with the signature passed back by the client and determines that the subscriber passes the authentication if the signatures are completely consistent. The system comprises the server, the client, the receiving equipment, an Internet and the Internet heterogeneous network. The identity of the subscriber is authenticated by the two dynamic passwords, and the transmission routes and the processing modes for the two dynamic passwords are different, so that interception, distortion and counterfeiting by a hacker during authentication are effectively prevented; and compared with the authentication method in which only one dynamic password is adopted, the authentication method is relatively high in security.
Description
Technical field
The present invention relates to the internet security field, relate in particular to two dynamic password client identity authentication methods in a kind of the Internet and system.
Background technology
Along with popularizing of internet, applications service, the transaction that the user carries out on network is more and more.Because opening, unreliability and the equity of the Internet make information security become a key issue.Especially concerning based on Web bank's service of the Internet; Information security be basis, most critical, need most the part of concern; Being the embodiment of Web bank's service ability, is the important barrier of protection clients fund safety, is the powerful guarantee of safeguarding that financial order is stable.
The user like transferred account service, payment transaction etc., must import correct password when using the high risk business of Web bank, bank just can provide service for the user.Usually; The password of user's input is the intrinsic password of its account; Because the intrinsic password of user's input must send the server of service center through the Internet to; So input the fail safe that intrinsic password can reduce transaction, rogue attacks person is easy to steal through modes such as network attacks user's intrinsic password.
In order to prevent because of the stolen danger that brings of user's intrinsic password, increased the mode that dynamic password verifies at present and concluded the business, promptly the user not only need input intrinsic password, the dynamic password that all can change in the time of also need importing each transaction.In the prior art; Provide the process of dynamic password mainly to comprise to the user: bank sets out dynamic password in advance; Set dynamic password is kept among dynamic password board or the USB KEY, and the user gets dynamic password board or USB KEY, therefrom obtains dynamic password.
Adopt in the process of the dynamic password that prior art provides, the user must get the dynamic password board or USB KEY just can obtain dynamic password from bank, thereby accomplishes follow-up process of exchange.After the dynamic password among dynamic password board or the USB KEY uses up; The user must get new dynamic password board or USB KEY to bank again, and, if dynamic password board or USB KEY lose; The user also must get to bank again, brings great inconvenience to the user.In addition, dynamic password is kept among dynamic password board or the USB KEY, in case dynamic password board or USBKEY lose, the dynamic password that can make transaction use is revealed, and has reduced the fail safe of transaction.In addition, because dynamic password board or USB KEY are independent peripheral hardwares, increased cost.
Summary of the invention
In order to solve the problems referred to above of prior art, the purpose of this invention is to provide two dynamic password client identity authentication methods in the low the Internet of a kind of strong security and cost and system.
To achieve these goals, the invention provides the two dynamic password client identity authentication methods in a kind of the Internet, it is characterized in that, comprising:

Step C: dynamic password A, business information and client identity information that the said server of said client-cache sends, and show said business information, wait for that the client imports said dynamic password B;
Step D: after said client receives the dynamic password B that receives on the said receiving equipment of client's input; Said dynamic password A, business information and client identity information are carried out digital signature form signature A '; Said dynamic password B, business information and client identity information are carried out digital signature form signature B '; Said dynamic password A, dynamic password B, business information and client identity information are carried out digital signature in the lump form signature C ', and the A ' that will sign, signature B ' and signature C ' send said server to;
Step e: said server carries out the digital signature same with said client with said dynamic password A, dynamic password B, business information and the client identity information of buffer memory, forms signature A ", signature B " with the C that signs ";
Step F: A will sign ", signature B " with signature C " compare with signature A ', signature B ' and signature C ' respectively, comparing result is all consistent, then authentication is passed through, said server is handled the instruction of said business to said client transmission permission client; Comparing result is all consistent, authentification failure then, and said server sends the instruction of dynamic password input error to said client.
As preferably, also comprise:
Step G: contrast is charged to comparing result in the system journal after accomplishing.
Preferred as further, also comprise:
Step H: after contrast was accomplished, said client was destroyed said dynamic password A, business information and the client identity information of buffer memory, and said server is destroyed said dynamic password A, dynamic password B, business information and the client identity information of buffer memory.
As preferably, among the said step B, said server sends said dynamic password B to said receiving equipment through SMS platform or direct-connected mail server.
