Abstract

The invention provides a one-to-many identity authentication system and method based on a dynamic password. The system comprises a subject, a plurality of objects and an authentication server; the subject is used for managing the plurality of objects, and when a certain object needs to be authenticated, generating a dynamic password corresponding to the certain object by using a dynamic password generation algorithm according to a subject key and an object unique identifier of the certain object, and transmitting the dynamic password to the certain object; the certain object is used for transmitting the own object unique identifier and the dynamic password transmitted by the subject to the authentication server; and the authentication server is used for generating a dynamic password corresponding to the object by using the same dynamic password generation algorithm according to the subject key and the object unique identifier, and confirming that the identity authentication of the certain object is successful when the generated dynamic password is consistent with the dynamic password transmitted by the object. According to the one-to-many identity authentication system based on thedynamic password provided by the invention, the safety and usability problems in a "one-to-many" password authentication scene are solved, and a safe and easy-to-use identity authentication method based on passwords is provided.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a one-to-many identity authentication system and method based on a dynamic password. Background technique [0002] In the process of accessing the network system, the password is usually used as the user's identity authentication credential. Password-based authentication can be divided into two types: static password-based authentication and dynamic password-based authentication. Because static passwords are fixed and easy to guess, the authentication method based on static passwords is not applicable in scenarios with high security requirements. In order to meet higher security requirements, people propose and use dynamic passwords to identify system users to confirm the legitimacy of system users' identities. Dynamic passwords have the advantages of unpredictability and ease of use, and can effectively meet the security requirements of identity authentication whe...
