椭圆曲线密码体制在PKI的应用

Application of Elliptic Curve Cryptosystem in PKI

PKI(Public Key Infrasture)是目前保障信息安全的最佳技术之一,是为用户提供信息安全服务的基础设施.认证机构是PKI中的一个实体,遵循PKI的策略,负责发布数字证书.椭圆曲线密码体制(ECC)具有密钥短、单位安全强度高、计算效率高等优势.在PKI中引入椭圆曲线密码体制更加适合网络安全的发展要求.

Public key infrastructure（PKI） is one of the best techniques for solving information security problem.Certification authority is the entity in PKI which is responsible for exacting compliance with PKI policy and issuing certificates.Elliptic curve cryptosystem has many advantages such as smaller keys,higher security and more efficient algorithms than traditional ones.Adding Elliptic curve cryptosystem to PKI makes certificates more suitable for the future development of network security.
