Outbound Authentication for Programmable Secure Coprocessors
Sean W. Smith
Dartmouth TR2001-401


A programmable secure coprocessor platform can help solve many security problems in distributed computing. These solutions usually require that coprocessor applications be able to participate as full-fledged parties in distributed cryptographic protocols. Thus, to fully enable these solutions, a generic platform must not only provide programmability, maintenance, and configuration in the hostile field---it must also provide outbound authentication for the entities that result. A particular application on a particular untampered device must be able to prove who it is to a party on the other side of the Internet.

To be effective, a secure outbound authentication service must closely mesh with the overall security architecture. Our initial architecture only sketched a rough design for this service, and did not complete it. This paper presents our research and development experience in refining and implementing this design, to provide PKI-based outbound authentication for the IBM 4758 Model 2 secure coprocessor platform.
