Abstract:
Aiming at the requirement that security and reliability is very high, this paper designs a high-confidence fault-tolerant computer system to combine trusted computing and high-reliability technology. Depending on technology of trusted computing, password support system is constructed based on TCM to achieve platform integrity, identity authentication and data security. Depending on fault-tolerant technology, system provides uninterruptable service in an error case. The prototype system is tested by experiment, and technical program is verified to be effective.
