Abstract: This paper proposes a safe scheme for network test systems based on campus network.Public-key authority(based on EEC),Key Distribute Center(KDC) and Advanced Encryption Standard(AES) are adopted to solve identity authentication,key distribution and data encryption,which can guarantee data in secret,integrity,authentication and non-repudiation.Therefore the whole system is safe.

摘要: 从信息安全的角度,运用了公钥认证(采用椭圆曲线密码算法),密钥分配中心(KDC),和最新的高级加密标准(AES),根据实际需要提出了一种新的加密方案,解决了基于校园网考试系统中各终端机身份认证,密钥分配,数据加密等问题。以上问题的解决能够保证传输数据的机密性、完整性、可鉴定性、不可否认性,从而整个系统是安全的。
