Abstract

The invention a remote identity authentication method based on a password, a smart card and biological features. The method includes the step of registration, the step of logging in and the step of authentication. According to the method, a registration center generates a first parameter set and stores the first parameter set onto the smart card; the smart card verifies local legitimacy of the identity of a user, and if the identity of the user is legal, first verification data relevant to random numbers are generated and sent to a server; the server verifies the legitimacy of the identity of the user, and if the identity of the user is legal, second verification data used for verifying the identity of the server are generated and sent to the smart card; the smart card verifies the legitimacy of the identity of the server, and if the identity of the server is legal, third verification data are generated and sent to the server; the server verifies the identity of the user for the second time, and if the identity of the user is legal, the server and the smart card generate the same session key. The method can resist server denial attacks, verification table theft attacks, replay attacks and the problem of forward secrecy.

Description

technical field [0001] The invention relates to the fields of information security and network technology, in particular to a remote identity authentication method based on passwords, smart cards and biometric features. Background technique [0002] With the rapid development of network technology and communication technology, traditional forms of identity authentication methods are no longer safe, user names and passwords can be stolen by attackers, smart cards are easily stolen or lost, and passwords may also be forgotten or leaked. Danger. However, biometric technologies such as fingerprints, faces, and irises provide a more reliable and automated means of authentication based on important physical or behavioral characteristics. These biometrics are usually universally available, unique and cannot be copied, lost and forgotten. [0003] Due to the above advantages, some remote user authentication schemes based on biometrics are designed to solve the single-password auth...
