Public key based authentication method for transaction delegation in service-based computing environments

摘要

A system and method for allowing access to data or processing on a remote computer. An authorizing computer provides client computers with a data specification and remote computer address along with an authorization code that is digitally signed or encrypted and that may only be used for a limited number of times. A client computer then accesses the remote computer by providing the digitally signed authorization code. The remote computer responds with the data or processing if the digital signature is successfully verified and the authorization code has been used fewer than the limited number of times.
