Checking Method, Checking Device and Checking System for Processor
First Claim
1. A checking method for a processor, comprising:
- determining 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; and
checking the checked processor according to the determination result, which further comprises;
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, the total checking length of the first checking mode is longer than the total checking length of the second checking mode.

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.

11. A checking device for a processor, comprising:
-
determining unit, configured to determine 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; and checking unit, configured to detect the checked processor according to the determination result, which further comprises; 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, the total checking length of the first checking mode is longer than the total checking length of the second checking mode. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
