Abstract

The invention discloses a remote identity authentication method based on passwords, smart cards and biometric features, including a registration step, a login step and an authentication step, wherein the registration center generates a parameter group 1 and stores the parameter group 1 into the smart card; The identity is verified locally, and if it is legal, the first verification data related to the random number is generated and sent to the server; the server verifies the legality of the user's identity, and if it is legal, the second verification data used to verify the identity of the server is generated data, and send it to the smart card; the smart card verifies the legality of the server identity, and if it is legal, generates the third verification data and sends the third verification data to the server; the server performs secondary verification on the user identity, and if it is legal, the server and The smart card generates the same session key. The method of the invention can resist the problems of denial server attack, verification table stolen attack, replay attack and forward secrecy.

Description

technical field [0001] The present invention relates to the field of information security and network technology, in particular to a remote identity authentication method based on passwords, smart cards and biological features. Background technique [0002] With the rapid development of network technology and communication technology, the traditional form of identity authentication is no longer safe. User names and passwords can be stolen by attackers. Smart cards are easily stolen or lost, and passwords are also forgotten or leaked. Danger. However, biometric technologies, such as fingerprints, faces, and irises, offer a more reliable and automatic means of authentication based on important physiological 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 ...
