Problems solved by technology

[0015] The technical problem to be solved by the present invention is to provide a dynamic password generation method and system for the deficiencies in the prior art, which can reduce the security risk of the mobile phone token and the dynamic key and the security risk caused by the loss of the hardware token, and solve the problem of hardware security. The problem that the token is not easy to carry, reduces the issuance cost of the hardware token password, and solves the problem that the hardware token password cannot be reused and shared

Embodiment Construction

[0037] The system architecture of the present invention is as figure 1 As shown, it contains three parts:

[0038] Business system, including user login, user authentication and time synchronization. Provide a login interface in the form of a user browser or client, accept user accounts and dynamic passwords entered by users, and submit them to the system platform for verification of dynamic passwords based on time synchronization technology. At the same time, it provides time synchronization with the user's mobile phone client.

[0039] The program of the mobile terminal (such as client and web application) provides an operation interface for generating a dynamic password, calls the token Applet on the SE to generate a password, and synchronizes the time with the business platform.

[0040] Token Applet is an application program on the secure element SE, which accepts the input of the mobile terminal and generates a dynamic password according to the input. The token applet...

Abstract

The invention discloses a dynamic password generating method and system. The method comprises the steps a PIN is input by entering a mobile terminal, and a dynamic password is requested to be generated; the mobile terminal reads system time of a mobile phone; the mobile terminal calls a token Applet of SE, and the dynamic password is requested to be generated; the input PIN is verified through the token Applet, and quitting is conducted if the input PIN is not consistent with a PIN in the SE; if the PIN passes through verification, the token Applet generates the dynamic password, and the generated dynamic password is returned to the mobile terminal; the dynamic password is displayed by the mobile terminal. The dynamic password generating method and system reduce security risks of a mobile phone token and a dynamic secret key and security risks after a hardware token is lost, resolve the problem that the hardware token is difficult to carry, reduce distribution cost of the password of the hardware token, and resolve the problem that the password of the hardware token can not be reused or shared.

Description

technical field [0001] The invention relates to a dynamic password generation method and system. Background technique [0002] A dynamic password is an unpredictable combination of random numbers generated according to a specific algorithm, and each generated password can only be used once within a specified time. The advantage is that one password is only used once in the authentication process, and another password will be used for the next authentication, making it difficult for criminals to counterfeit the identity of a legitimate user, and the user does not need to memorize the password. At present, this method is widely used in online banking, online games, telecom operators, e-commerce and other fields. [0003] At present, the mainstream methods for generating dynamic passwords include hardware tokens, SMS passwords, and mobile phone tokens. [0004] 1. SMS password [0005] The SMS password requests a dynamic password containing 6 or more random numbers in the fo...
