Design of CA System Based on Elliptic Curve Cryptosystem
SU Jiu-qing · Computer Knowledge and Technology · 2010
This paper introduced the operating mechanism,function and basic components of Public Key Infrastructure.The basic theory of elliptic curve cryptosystem is introduced.Especially elliptic curve digital signature algorithm ECDSA is introduced.Based on the ECC's property of reductions in storage space,bandwidth and smaller length key,this paper presents a design of CA.It is secure under the assumption that ECC discrete logarithm is hard to slove.This design can be used in e-business.
