Problems solved by technology

Most of the existing identity authentication systems use public-key cryptography, and the public-key cryptography is mostly based on large number calculations, resulting in a huge computational load for the entire authentication system. This is the main reason why traditional authentication protocols cannot be directly applied to the mobile business environment. reason
[0006] (3) A limited-length password sequence or hash chain needs to be registered repeatedly
And if the fixed-length hash chain value is calculated once at the mobile terminal, since the length N is usually a large integer, multiple hashes will affect the authentication efficiency of the mobile terminal
[0007] (4) The password se

Embodiment Construction

[0083] Authentication model architecture 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, there will be no communication between the mobile device 2 and the authentication server 3 . If the first-level verification is passed, the mobile device 2 automatically communicates with the authentication server 3, and the user 1 cannot see 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 achieve the security of the mobile terminal itself, the security of the wireless communication network, the identity authentication and non-repudiation of both parties in the mobile commerce transaction. Each aspect of the requirements, these four security requirements are all based on the authentication problem 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. It is the most basic security service, and other security services must rely on it. Once the identity authenticat...
