Digital Signature Scheme of a High Efficiency Elliptic Curve
Shi Rong-hu · Microcomputer Information · 2012
The classic elliptic curve digital signature algorithm(ECDSA) is described basically.We investigate the requirements of application system and efficiency of ECDSA,improve ECDSA.The scheme is based on the elliptic curve discrete logarithm problem.Compared with ECDSA signature scheme,the scheme from the establishment of parameters to signatures and validation process,no use time-consuming for inverse.The research result shows that this scheme is correct and safe.It inherited the traditional ECDSA signature scheme's advantages,such as low computation load,storage requirements is not high,small occupied bandwidth.At the same time,it improve the operation speed of digital signature and save the system resources.
