Problems solved by technology

The power consumption analysis attack uses the correlation between the calculation results generated by the cryptographic components during operation and the power consumption to analyze. Using this correlation, the attacker can analyze the sensitive data or secret data in the cryptographic components. resulting in a data breach

Abstract

The invention belongs to the field of circuit electronics, and particularly relates to a power consumption constancy circuit unit based on a pre-charging logic and mask technology, the power consumption constancy circuit unit is composed of two monorail mask type pre-charging gate circuit units, and the monorail mask type pre-charging gate circuit units are monorail mask type OR gate logic units or monorail mask type NOR gate logic units; according to the composition mode, the single-rail mask type OR gate logic unit and the single-rail mask type NOR gate logic unit form a double-rail mask type OR gate logic unit. According to the invention, the double-track pre-charging logic is combined with the mask technology, so that the output result is randomly overturned while the constant power consumption is satisfied, and the power consumption analysis attack resistance of the circuit is improved.

Description

technical field [0001] The invention belongs to the field of circuit electronics, in particular to a power consumption constancy gate circuit unit based on precharge logic and mask technology. Background technique [0002] Since the simple power analysis attack and differential power analysis attack methods were proposed, many researchers have no longer focused on strengthening the security of cryptographic algorithm protocols, but to analyze the unavoidable The side channel information that will be generated. As an effective and easy-to-operate attack method in side channel attacks, power analysis attack has received more attention recently. The power consumption analysis attack uses the correlation between the calculation results generated by the cryptographic components during operation and the power consumption to analyze. Using this correlation, the attacker can analyze the sensitive data or secret data in the cryptographic components. resulting in data leakage. Ther...
