ABSTRACT:
Authenticating a remote process operating in an address space different than that of a local process includes the steps of creating, by the local process, a tamper resistant module containing a temporary secret, sending the tamper resistant module and a challenge from the local process to the remote process, executing the tamper resistant module by the remote process and recovering the secret when the integrity of the remote process is verified by the tamper resistant module, encoding the challenge using the secret to produce a response, sending the response to the local process, and decoding the response by the local process. Optionally, the tamper resistant module includes a request for information from the second process and the response includes the answer to the request for information.
