High-performance ECC coprocessor system resistant to power consumption attack

Abstract

The invention discloses a high-performance ECC coprocessor system resistant to power consumption attack. The system comprises an ECC master controller, a finite field arithmetic unit, a scalar multiplication module, a random number generator and a hash operation module. The ECC master controller controls all the modules to cooperatively complete operation and feeds back state signals to the register set, basic modular operation is completed by calling the finite field operation unit, then data is sent to the scalar multiplication module, and the functions of the point doubling point operation module, secret key scanning, coordinate conversion, y coordinate recovery and power consumption balance are completed. Wherein the random number generator is used for generating random Z coordinates in scalar multiplication operation, and the Hash operation module completes preprocessing of input messages, so that the efficiency of digital signature is improved, and finally encryption and decryption functions and digital signature verification functions are completed. The method has the advantages of being low in space complexity, simple, regular and easy to modularize, has the advantages of performance and area overhead, and meets the application requirements of ECC in the specific field.

Description

technical field [0001] The invention belongs to the technical field of cryptographic circuit design, and in particular relates to a high-performance ECC coprocessor system resistant to power consumption attacks. Background technique [0002] In recent years, with the rapid development of information technologies such as artificial intelligence, 5G and quantum communication, information security is facing severe challenges. Asymmetric encryption algorithms mainly include DSA, RSA, ECC, IBC, and ELGamal, etc., and ECC is more secure than RSA of the same level, and the key size is smaller. Compared with others, the encryption speed is faster, saving energy, bandwidth and storage. It is widely used as an algorithm with higher security strength, and at the same time, it puts forward higher requirements for the processing speed of the elliptic curve cryptosystem. ECC implementation is mainly divided into hardware implementation and software implementation. Now 5G has become a h...
