When the software industry discusses software integrity, the current
meaning is the protection of static software modules (e.g., by verifying
the signature of their originator). In contrast, dynamic software
authentication in real-time during execution is a known problem without
a satisfactory solution. Specifically, how to ensure that a trusted code
(i.e., the software as was specified and implemented) is running on an
untrusted machine at all times and that the original code functionality
has not been modified prior to or during run-time, is an open research
challenge.
