Uniform modular framework for a host computer system

摘要

A security framework for a host computer system (105) which allows a host to control access to a compliant security token (75) by ensuring enforcement of established security policies administered by a middleware application. Processing between the host computer system (105) and the security token (75) is performed using one or more modular security application agents. The modular security application agents are counterpart applications to security applications installed in the security token (75) and may be retrieved and installed upon to ensure compatibility between counterpart token and host security applications. The security policies (152C) are a composite of host security policies (152) and token security policies (184) which are logically combined by the middleware application at the beginning of a session.
