摘要：The principles of the present invention relate to systems, methods, andcomputer program products for more efficiently and securely authenticating computingsystems. In some embodiments, a limited use credential is used to provision morepermanent credentials. A client receives a limited-use (e.g., a single-use) credential andsubmits the limited-use credential over a secure link to a server. The server provisions anadditional credential (for subsequent authentication) and sends the additional credentialto the client over the secure link. In other embodiments, computing systems
automatically negotiate authentication methods using an extensible protocol. A mutuallydeployed authentication method is selected and secure authentication is facilitated with atunnel key that is used encrypt (and subsequently decrypt) authentication contenttransferred between a client and a server. The tunnel key is derived from a shared secret(e.g.., a session key) and nonces.
