A remote authentication protocol method based on biometrics

Abstract

The invention provides a remote protocol authentication negotiation protocol method based on biological features and belongs to the field of information safety. An efficient elliptic curve coding system is adopted. The method comprises the following steps that (1) system initialization is carried out to generate elliptic curve data; (2) a user submits register information to a server through a safe channel, and the server conducts data processing and then stores the information into an intelligent card and sends the information to the user through the safe channel; (3) a user needs to calculate login information and sends the login information to the server; (4) the purpose of authentication and key negotiation between the user and the server can be achieved through two times of hand shaking, and a session key is generated; (5) the user can achieve the purposes of changing a password and the biological features through the operation of the intelligent card without the assistance of the server. By means of the design, the protocol is high in safety, all mentioned known attacks can be resisted, meanwhile, dynamic identity is adopted, the anonymity of the user is protected, and the calculation performance is also greatly improved. The method is suitable for online education, remote medical and other remote authentication systems.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a remote authentication protocol method based on biometric features. Background technique [0002] The development of communication technology provides a scalable platform for various services, and remote users can access servers from anywhere. Telematics systems offer unique online service opportunities so that users do not need a physically present service center. These services employ authentication and key agreement protocols to ensure authorization and secure access to resources. In 1981, Lamport first proposed a password-based authentication protocol, which has been widely used. However, because passwords need to be stored and are easily forgotten and lost, simple password-based authentication protocols cannot meet the needs of complex network environments. Factors such as biometric features are gradually used in protocol design, and a multi-facto...

AI Technical Summary

Problems solved by technology

In recent years, a large number of biometric-based remote authentication protocols have been proposed, but none of them can provide sufficient security performance, and there is still room for improvement in computing performance.

In 2014, Huang Chaoyang proposed an authentication protocol based on biometric features. However, his protocol has defects such as inability to protect user anonymity, inability to resist denial-of-service attacks and private key leakage and impersonation attacks, and high computational consumption.
