ABSTRACT:
In the remote trusted path invention, secure systems may provide a mechanism for the user to establish a trusted path for direct communication with the system's trusted computing base for security-critical operations. This invention allows users to request such a trusted path from remote systems using a new TELNET option and command, in a system-independent, confirmed, backward-compatible manner. It also describes how to implement remote support for such a trusted path in systems which use a Secure Attention Key mechanism such as Secure AIX.
