The solution of two-factor authentication

Taking two-factor dynamic authentication as an example, this paper introduces the solution of two-factor authentication. A two-factor dynamic authentication solution consists of three main components: an easy-to-use token, a powerful management server and an agent software.

1. Token. Tokens enable users to gain protected access to resources after proving their identity. The token produces a random but specific "seed value" that is automatically updated every 60 seconds, and its number is valid only for the specified user at a specific time.

The user's password and the random "seed value" of the token make it difficult for the user's electronic identity to be imitated, embezzled or destroyed.

two。 Agent software. Agent software plays a role between end users and network resources that need to be protected. When a user wants to access a resource, the agent software sends the request to the user authentication engine of the management server and releases it after the authentication is passed.

3. Manage the server. The management server combines a high-performance authentication engine with centralized management capabilities. When the management server receives a request, it uses the same algorithm and seed value as the user token to verify the correct tokencode.
