Side channel attack simulation system of cryptographic chip

Abstract

The invention belongs to the technical field of security testing, and particularly relates to a side channel attack simulation system of a cryptographic chip. The side channel attack simulation systemcomprises a system configuration module, a simulator and an analyzer. According to the method, the thought of software and hardware collaborative design is adopted, and a side channel attack simulation evaluation scheme is designed through a method of separating a leakage simulation mechanism from a security analysis strategy. Simulation implementation and analysis implementation of bypass leakage are separated, a component technology is adopted for packaging the bypass leakage, and high flexibility is achieved. Different bypass leakage information and attack strategies can be added into theenvironment in the form of components, so that a tester can flexibly select test data and analysis strategies according to test requirements, and simulation analysis can be performed on bypass attacksin the design stage of a cryptographic chip.

Description

technical field [0001] The invention belongs to the technical field of security testing, and in particular relates to a bypass attack simulation system of a cryptographic chip. Background technique [0002] Side-channel attack is a security testing method, that is, to find the existing security loopholes (or to crack the secret) by testing the leaked information of the cryptographic chip. This analysis method requires the support of corresponding bypass simulation tools, that is, simulates the bypass leakage information of cryptographic chips during operation through simulation technology in the design stage. [0003] Test methods for side channel attacks can be divided into two categories: test methods for side channel attacks in the later stage of chip production and test methods for side channel attacks in the chip design stage. [0004] The side-channel attack analysis method in the later stage of chip production is a relatively common method. Its main feature is to tes...
