Embodiment Construction

[0024] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the implementations shown and described in the drawings are only exemplary, intended to explain the principle and spirit of the present invention, rather than limit the scope of the present invention.

[0025] The embodiment of the present invention provides a hardware vulnerability assessment method based on HDL codes, which starts from analyzing the vulnerability of links between different modules to evaluate the vulnerability of programs step by step. In order to facilitate the research, the embodiment of the present invention uses the concept of "graph" to first establish the abstract connection topology of the program modules through code analysis, and then evaluate each module of the program based on the module connection topology and the importance of links and modules grammatical fragility.

Abstract

The invention discloses a hardware vulnerability evaluation method based on an HDL (Hardware Description Language) code. A program developed by the HDL is taken as the input of grammar semantic parsing, the connection topological relationship of each HDL module is established, the vulnerability weight of each edge is calculated on the basis of the connection topological relationship to evaluate the vulnerability of each module, and furthermore, vulnerability grade division is carried out on each module. By use of the method, guidance is provided for the hardware vulnerability detection of theHDL program so as to bring convenience for reinforcement design in subsequent program development to improve the stability and the reliability of a program system.

Description

technical field [0001] The invention belongs to the technical field of hardware security, and in particular relates to the design of a hardware vulnerability assessment method based on HDL codes. Background technique [0002] Based on the wide application of FPGA and ASIC, more and more programs are developed in Hardware Description Language (HDL, Hardware Description Language), and it is becoming more and more difficult to guarantee the security and reliability of programs using HDL. Just like various software security holes, there are also various security holes and design flaws in the HDL program development process. HDL language and software language have certain similarities in semantics, so the analysis and research methods of software vulnerability can be used for reference, which provides a direction for the hardware vulnerability of HDL programs. [0003] Software analysis takes "whether the software needs to be run" as the criterion in the analysis process, and so...
