Security detection method for design of cryptographic algorithm hardware

Abstract

The invention discloses a security detection method for the design of cryptographic algorithm hardware. The method comprises the steps of analyzing cryptographic algorithm, and adding protective measures into the cryptographic algorithm according to an analyzing result; performing architectural design on password hardware, and formulating and adding the hardware protective measures; programming the password hardware, and generating an ASIC (Application Specific Integrated Circuit) password chip circuit layout according to the programming result; and performing power resistance analysis on the password chip, and verifying the security of the chip, including the acquiring of power consumption information and the analysis of data. According to the method, the characteristic of an EDA (Electronic Design Automation) tool capable of stimulating the chip operation power consumption to obtain the stimulated power consumption of the chip at a chip design early stage can be maximally utilized, so that the stimulated power consumption is more accurate in operation, lower in noise, simpler in power alignment, and is more likely to perform power consumption attack analysis in comparison with the operation consumption of the chip. The stimulated and synthesized results are only analyzed and the real chip is not needed, so that the research cost is low, and the total cost for producing the password chips in a company can be reduced.

Problems solved by technology

If the security of the cryptographic chip is judged after its production, such as DPA (Differential Power Analysis) attack on it, relatively expensive tools are usually required, and the analysis conditions are relatively difficult

In addition, if the security of the chip is too low, it needs to be improved, which will greatly increase the production cost of the chip
