摘　　要：ECC密码体制的应用前景日益广泛,但是签发管理ECC证书的成熟CA产品却很少。在CA认证系统中引入椭圆曲线密码体制,实现了申请、签发、验证、查询和撤销ECC数字证书的功能。在同等安全强度下,系统发布的ECC证书比RSA证书体积更小、占用带宽更少而且性能更高,更加适合未来网路安全的发展需求。ECC has been used more and more widely,but the mature products of CA for issuing and managing ECC certificates are quite few.The paper adds elliptic curve cryptography to CA system and implements the functions such as application,issue,verification,search and revocation of ECC digital certificates.The testing results show that ECC certificates issued by CA are smaller and more efficient with the same strength compared with RSA certificates.They are more suitable for the development of future network security.
