在公钥基础设施中，认证中心作为可信第三方机构，其安全性尤为重要。与其他诸如RSA等公钥密码体系相比，椭圆曲线密码体系密钥更短、效率更高。使用Java编程技术设计一个基于椭圆曲线密码体系的认证中心，并给客户签发和验证X.509数字证书。

CA (Certificate Authority) acts as the trusted third party in PKI (Public Key Infrastructure), hence it’s significant to en-sure the CA system’s security. The ECC (Elliptic Curve Cryptography) has the advantages of shorter key and higher efficiency, comparing with other public key cryptographies such as RSA. The purpose of this work is to design and implement a CA based on ECC by using Java programming technique, which can sign X.509v3 digital certificate to client and then validate client certificate.
