Abstract

The invention relates to an SM2 elliptic curve signature verification hardware system and method for resisting differential power consumption attack, the anti-differential power consumption attack method of the invention is applied to scalar multiplication, by adding the improved randomized scalar method to the point multiplication operation, the correlation between the real key information and the power curve is destroyed, which makes it difficult for the power analysis to obtain the information to resist the power analysis, and ensures the security of the differential power attack, thus playing a very good role in resisting the differential power attack. And this method is simple and easy to implement, and can be integrated into a variety of encryption chips and other hardware devices.

Description

technical field [0001] The invention relates to the technical field of SM2 cryptographic algorithm, in particular to an SM2 elliptic curve signature verification hardware system and method against differential power consumption attack. Background technique [0002] Information security is an important issue related to national sovereignty and security, social stability and national cultural heritage. Among them, encryption technology is the core technology to ensure information security, and it is an indispensable technology to ensure information integrity, confidentiality and security. [0003] With the development of cryptography and computing technology, the currently commonly used 1024-bit RSA algorithm is facing serious security threats. Due to the advantages of the SM2 algorithm, such as high security, small amount of calculation, and fast processing speed, our national password management department decided to use it after research. The SM2 elliptic curve cryptograph...
