摘要
由于高校光传输网数据对于安全性的要求较高.为降低数据泄露风险,提出高校数据云网光传输网明密文混合隐私保护方法.去标识化处理传输过程中的敏感数据,基于数学的同态加密算法—ElGamal对高校数据云网光传输网数据进行同态加密处理.设置特定的加密密钥,对明文数据包和同态加密处理后的密文数据包进行解密.在测试结果中,仅分布式拒绝服务攻击和窃听攻击作用下的信息缺失程度达到了 3.0％以上,其他攻击作用下的信息缺失程度均稳定在3.0％以内.
Abstract
Because the data in optical transmission network in colleges and universities require high security,in order to reduce the risk of data leakage,a hybrid privacy protection method of clear and encrypted text in optical transmission network of university data cloud network is pro-posed.The sensitive data in the transmission process is de-identified,and the homomorphic en-cryption algorithm-—ElGamal is used to encrypt the data in the optical transmission network of university data cloud network.Set a specific encryption key to decrypt the plaintext data packet and the ciphertext data packet after homomorphic encryption.In the test results,the degree of information loss under distributed denial of service attack and eavesdropping attack is above 3.0％,and the degree of information loss under other attacks is stable within 3.0％.
