Abstract

The invention discloses a side channel energy analysis attack method for the multiplication output when the power residue calculation M-ary is realized in the RSA cryptographic algorithm. CPA attack. It includes the following steps: (1) collect signals and establish a sampling matrix; (2) select the multiplication output as the attack object; (3) determine the correlation model; (4) guess the round index value and calculate the intermediate value matrix; (5) calculate Simulate the energy consumption matrix; (6) Calculate the linear correlation coefficient between the matrices determined in (1) and (5), and attack the correct round index. (7) Repeat (4) to (6), the attack gets all the correct round indices, and the complete indices are obtained after concatenation. The method of the invention provides a new M-ary side channel attack method, which enhances the flexibility, effectiveness and success rate of RSA cryptographic algorithm analysis attacks.

Description

technical field [0001] The invention relates to the field of analysis and detection of cryptographic algorithms, in particular to a method for analyzing side channel energy analysis attacks aimed at the multiplication output when the power residue calculation M-ary in the RSA cryptographic algorithm is realized. Background technique [0002] With the development of information and analysis circuit technology, the cracking of hardware cryptographic electronic equipment no longer simply stays on the protocol and algorithm, but starts from the information leaked in the process of processing data to crack. In the process of processing information, hardware cryptographic electronic equipment leaks information such as energy, electromagnetics, errors, and time. Using these leaked information to attack cryptographic electronic equipment is the so-called Side Channel Attacks. It can be divided into energy analysis attack, electromagnetic attack, error attack, etc. Among them, energy...
