Abstract
The method of delegating authentication, within a chain of entities, relies upon a recording of at least a portion of a TLS handshake between a gateway device and user, in which the user needs access to a desired server. The method then relies upon re-verification of cryptographic evidence in the recorded portion of the TLS handshake, which is forwarded either (1) to the server to which access is desired, in which case the server re-verifies the recorded portion to confirm authentication, or, (2) to a third party entity, in which case the third party entity confirms authentication and provides credentials to the gateway server which then uses the credentials to authenticate to the server as the user.
