Failure recovery mechanism to re-establish secured communications

Abstract:

Embodiments of the present invention include techniques for reestablishing a secure communication channel between a client machine and a server machine. A client machine receives, from a server machine, a first message generated in connection with a first master token. The client machine detects an error condition associated with the first message. The client machine transmits, to the server machine, a second message generated in connection with a pre-provisioned key that includes a request for a new master token. The client machine receives, from the server machine, a third message that includes a second master token. The client machine transmits, to the server machine, a fourth message generated in connection with the second master token.
