Embodiment Construction

[0042] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0043] This protocol uses an efficient elliptic curve cryptosystem algorithm, through a reasonable design of the protocol process, based on multiple factors such as biometric features, passwords and smart cards, it has strong security performance and fast calculation speed, and can be specifically applied in telemedicine and other systems, such as figure 1 The specific operation shown is as follows:

[0044] (1) System initialization

[0045] Server S will generate system parameters through the following steps.

[0046] (1) S selects the elliptic curve E:y 2 ≡x 3 +ax+b(modp),E p (a, b) is the nth-order point addition group of the elliptic curve E, and P is its generator, that is, n·P=O.

[0047] (2) S selection As your own private key and save it, calculate Y=s·P as the public key, and then choose a one-way hash function H ...

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...
