Rapid detection method for multi-dimensional vulnerability of hardware system

Abstract

The invention discloses a rapid detection method for multi-dimensional vulnerability of a hardware system. The method comprises the following steps: firstly, extracting a hardware system feature set according to the structure of the hardware system; secondly, constructing a hardware system data and vulnerability database based on the hardware system feature set; and finally, finding a vulnerability entry and a hardware system which can be successfully matched through a vulnerability search algorithm to realize multi-dimensional vulnerability detection. According to the method, vulnerability detection can be carried out based on the design document and the vulnerability database of the hardware system, multi-dimensional vulnerability generated by cooperative work of different dimensions in the system is found in the design stage of the hardware system, and the system architecture is supported to be changed in time in the design stage to eliminate the vulnerability. Therefore, the invention provides an effective detection method for the vulnerabilities introduced in the hardware system design, and ensures the security of the hardware system design.

Description

technical field [0001] The invention relates to the field of hardware security, in particular to a fast detection method for multi-dimensional vulnerability of a hardware system. Background technique [0002] As the basic equipment of the Internet, the hardware system can only perform its functions properly only if it can reliably collect, exchange and process data. For a long time, hardware systems are considered to be safe and reliable after being manufactured. However, with the development of information technology, more and more attacks are aimed at hardware systems, so hardware vulnerability analysis methods are urgently needed. [0003] The vulnerability analysis of hardware systems mainly includes three stages: design, testing and operation. However, according to the literature of Bakirtzis G et al., it is known that most of the hardware defects are introduced in the design stage (see "Data-driven vulnerability exp loration for design phase" system analysis", Bakirtz...
