Problems solved by technology

But the S / Key system still has serious flaws
Firstly, the S / Key system cannot resist decimal attacks; secondly, if the attacker obtains the user's secret password through keyboard monitoring and other attack methods, he can still pretend to be a legitimate user and successfully pass the authentication.
[0019] In addition, all biometric-based identification technologies use the extracted biometric data as an identification code, so they are easily intercepted illegally during transmission.

Embodiment Construction

[0031] A two-way identity authentication method based on the combination of a one-time password of the S / Key system and biometric identification comprises the following steps:

[0032] (1) The client user sends an identity authentication request to the server;

[0033] User ID A ;

[0034] (2) The server sends a response message to the client according to the username sent by the client:

[0035] The server sends the iteration value N, the seed value S and the one-time password P used to decrypt the biometric value during the last authentication to the client i-1 ;

[0036] (3) The client calculates the current one-time password according to the current iteration value N-i, the seed value S, and the secret passphrase W. Calculated as follows:

[0037] P i =H N-i (W+S);

[0038] (4) The client saves the current password P i , and for the current password P i Perform another hash operation, calculated as follows:

[0039] P' i-1 =H(P i );

[0040] The client will P...

Abstract

The present invention relates to an ID identification method based on the S / Key system. The present invention submits the registration data comprising a user name, a code and password, iteration value and the biological property value to an identification server through a user side; the server forms the seed value corresponding to the user and calculates the first one-off password of the password sequence. A duplex identification between the client side and the server which is also the duplex identification of the combination of the one-off password of the registered user and the biological proper value is implemented in the process of user ID identification. .

Description

technical field [0001] The invention relates to an identity authentication method in the field of computer network security, in particular to an identity authentication method based on an S / Key system. Background technique [0002] Identity authentication is the first barrier in the network security system, and other security services depend on it. Once the identity authentication system is breached, all the security measures of the system will be useless. At present, the main identity authentication method is still static identity authentication based on user name / password. However, there are many disadvantages in this authentication. Firstly, the user must memorize some complex passwords, and secondly, the static passwords are easy to be intercepted during transmission. Currently, a more secure identity authentication method is to adopt a one-time password authentication method, or an identity authentication method of biometric identification. The main idea of ​​one-tim...
