Abstract
A checking method for a processor is provided. The checking method first determines whether a checked processor satisfies a security-sensitive condition including one or more of security-sensitive instruction, processor running mode, security-sensitive input/output operation, security-sensitive application, and user-defined security level. Then, the checking method checks the checked processor according to a determination result, which further includes: when the checked processor satisfies the security-sensitive condition, checking the checked processor according to a first checking mode; and when the checked processor does not satisfy the security-sensitive condition, checking the checked processor according to a second checking mode; wherein for the same running process of the checked processor, a total checking length of the first checking mode is longer than that of the second checking mode. Also provided is a checking device for a processor and a checking system for a processor.
