基于椭圆曲线的数字签名和加密算法
Digital Signature and Encrypt Algorithm Based on Elliptic Curve
摘要
Abstract
Applying EIGamal signature scheme to the elliptic curve cryptosystem may introduce an undefined operation of point multiplex in elliptic curve. In order to solve the problem, this paper improves processes of signature generation and validation, using a simple algebra operation instead of multiplication operation, and presents feasibility and security analysis. Menezes Vanstone(MV) algorithm is improved to reduce its data expand rate. Experimental results show that its operation speed is faster than RSA or ECC-E. Execution efficiency and key length of the improved algorithms make them more efficient in the application of smart card computation.关键词
