Safety detection method and device

Abstract

The invention provides a safety detection method and device. At least one safety detection strategy is made in advance; a safety detection strategy corresponding to current safety requirements can be acquired during safety detection; operation behaviors on a bus can be collected; then safety detection is conducted to the operation behaviors based on the safety detection strategy, and a first detection result corresponding to the safety detection strategy can be achieved; and all first detection results corresponding to the safety detection strategies are collected to achieve a second detection result for the operation behaviors. The operation behaviors are processing behaviors for indicating an integrated circuit system based on bus communication, so safety strategies-based safety detection to the operation behaviors is safety detection to the processing behaviors of the integrated circuit system; and the technical scheme realizes safety detection to the integrated circuit system of a bus structure.

Description

technical field [0001] The invention belongs to the technical field of bus behavior detection, and more specifically, relates to a safety detection method and device. Background technique [0002] At present, society's dependence on information has reached a very high level, and information security has become a key issue related to politics, economy, military affairs and daily life. In terms of information security, the security of the hardware structure and the security of the operating system are the basis of information security, and technologies such as cryptography and network security technology are the key technologies of information security. Correspondingly, in terms of hardware structure, there are many attack methods, including: destructive physical attacks, non-invasive side-channel attacks, and intrusive attacks. [0003] For destructive physical attacks, a sensor detection circuit can be added to the integrated circuit system. When the sensor detection circui...
