A dual-edge trigger-driven logic system and a method for resisting energy analysis attacks

Abstract

The invention discloses a double-edge triggering driving logic system and a method for resisting energy analysis attacks. The double-edge triggering driving logic system comprises signal sources, a control unit, a driving logic circuit and a driving logic compensation circuit. The system is utilized to replace standard signal sources and the driving logic circuit, safety is improved, a reset signal with the length being half of a clock period is generated through the control unit, two clock periods outputting a group of data are compressed into one clock period, and therefore working efficiency of whole chip hardware equipment cannot be reduced.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a double-edge trigger driving logic system and a method for resisting energy analysis attacks. Background technique [0002] At present, with the advancement of science and technology, various chip hardware devices have been widely used due to their small size, fast computing speed, diverse shapes, applicable to various e-commerce scenarios and long service life. market prospects. [0003] With the wide application of chip hardware devices, its side channel security issues are gradually exposed. Through the analysis of chip energy consumption, the information processed by the chip can be detected, which leads to information leakage accidents. [0004] In information theory, the Hamming distance (HD) between two equal-length bit strings is the number of different bits in the corresponding positions of the two bit strings; The Hamming distance of the string, that is, the number o...
