SYSTEM AND METHOD FOR IDENTITY-BASED ENTITY AUTHENTICATION FOR CLIENT-SERVER COMMUNICATIONS

摘要

The invention provides a system (100) for identity-based entity authentication for client-server communications comprising: a trusted authority module (110) configured to register at least one client and at least one server involved in the client-server communications and generate public parameters and secret parameters for use in the authentication; a server module (120) configured to securely store secret parameters for the server to authenticate the server to the client, and to authenticate the client to the server; a client module (130) configured to verify the authenticity of the server and to authenticate the client to said server; and a protocol module (140) configured to provide mutual authentication between the client and the server; characterised in that the protocol module (140) provides mutual authentication between the client and the server using ID-based challenge-response protocol and that the server module (120) authenticates the client to the server using ID-based authentication.
