Steady rollback and recovery policy based on integrity measurement

As to distributed processing environment, the intractable problem is that process´s current state is indeterminate, which could bring some security issues such as diffusing action. We put forward a checkpoint of integrity measurement (CPIM) arithmetic. The CPIM arithmetic could control process´s state when process encounters an integrity measurement checkpoint, which would solve the problem that the running state of parallel software is indeterminate. The virtue of CPIM arithmetic is simple and low-cost. We also provide implementation scheme and prototype for evaluating overhead and performance.
