"Trusted" Computing - Technologies, Opportunities and Problems

In this paper technologies, opportunities and problems of trusted computing are presented. Some of the problems that the system encounter includes measurement of software not people, inflexibility, hard failure, migration of virtual machines using trusted computing, change management, audit and economic effects. The solutions to this problems are physical separation, policy enforcement within the OS, and using virtualisation as a barrier. Also, it helps if it has a hardware assisted virtualisation and security, trusted computing and virtual machines and trust in the system.
