Embodiment Construction

[0084] Authentication model schema such as figure 1 As shown, the model divides the authentication into two levels. The first level is the authentication of the identity of the user 1 by the mobile device 2, and the second level is the two-way identity authentication between the mobile device 2 and the authentication server 3. The first level verifies that the user 1 using the mobile device 2 is a legitimate user, and the second level verifies the legitimacy of the mobile device 2 and the authentication server 3, that is, it is not a counterfeit terminal. If the first-level verification fails, then the mobile device 2 and the authentication server 3 will not communicate. If the first-level verification is passed, the mobile device 2 automatically communicates with the authentication server 3, and the user 1 is invisible to the process and can only know whether the verification is passed.

Abstract

The invention provides a mobile commerce identity authentication method. In the method, key negotiation is realized by the most efficient elliptic curve-based public key cryptosystem in public key cryptosystems. An elliptic curve algorithm has the characteristics of low calculated amount and high safety, so the elliptic curve algorithm is used for generating a public key and a private key, and a public key cryptosystem without a third-party is realized and applied to the two-way authentication service of a client and a server.

Description

technical field [0001] The invention belongs to the technical field of mobile commerce information security, and in particular relates to a mobile commerce identity authentication method and system. Background technique [0002] According to the security issues considered by traditional e-commerce and the characteristics of mobile commerce itself, the security of mobile commerce needs to meet the security of the mobile terminal itself, the security of the wireless communication network, and the identity authentication and non-repudiation of both parties in the mobile commerce. These four security requirements all take identity authentication as the basis for realizing the security requirements. It can be seen that the status of the identity authentication system in the security system is extremely important, and it is the most basic security service, and other security services must depend on it. Once the identity authentication system is breached, all the security measures...
