The TrustedFlow/spl trade/ protocol - idiosyncratic signatures for authenticated execution

We present a software solution to the problem of remotely authenticating software during execution, which aims at assuring that the software is not changed prior to and during execution. The solution is based on a flow of idiosyncratic signatures that is generated by a function hidden in the software to be authenticated and validated by a remote computing component. The TrustedFlow/spl trade/ approach is complementary to many current enhancements for secure computing and networking: while other approaches provide privacy and authentication protecting from the attacks of a man in the middle, TrustedFlow/spl trade/ protects from the attack of a man at the edge.
