Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In the low-complexity identity authentication method based on smart card multi-server environment proposed by the present invention, three participants are included: user U i , the server S and the registration center RC, where the registration center owns the system key x and shares the key with the servers in the system.

[0022] A low-complexity identity authentication method based on a smart card multi-server environment, including a registration step, a login step and an authentication step, wherein the registration step further includes that the registration center and the smart card c...

Abstract

The invention discloses a low-complexity identity authentication method based on an intelligent card and under a multiserver environment. The low-complexity identity authentication method comprises the steps of registering, logging and authentication, wherein the registering further comprises the steps that registering information of a user is converted by a registration center and the intelligent card and then is stored in the intelligent card; the logging further comprises the steps that the intelligent card carries out local legitimacy verification on the identity of the user, and if the identity of the user is legitimate, a random number is generated, and first verification data are generated and sent to a server; the authentication further comprises the steps that the server carries out the legitimacy verification on the identity of the user, and if the identity of the user is legitimate, second verification data are generated and sent to the intelligent card; the intelligent card carries out the legitimacy verification on the identity of the server, and if the identity of the server is legitimate, third verification data are generated and sent to the server; the server carries out secondary verification on the identity of the user, and if the identity of the user is legitimate, the server and the intelligent card generate the same session key. The low-complexity identity authentication method avoids intelligent card losing attacks and impersonation attacks.

Description

technical field [0001] The invention relates to the technical field of information security and communication, in particular to a low-complexity identity authentication method based on a smart card multi-server environment. Background technique [0002] In 1984, the concept of an ID-based cryptographic system was first proposed by Shamir. The main advantage of this program is simple password management. In real life, there are multiple servers that can provide resource information for users, so authentication schemes in a multi-server environment have gradually attracted people's attention. Most multi-server password authentication schemes are based on static IDs, so malicious attackers can use this information to track and identify user requests. [0003] In 2004, Professor Wen-Shenq Juang of National Kaohsiung First University of Science and Technology proposed a multi-server remote authentication protocol based on cryptography. This scheme has many advantages, such as ...
