Mixed Privacy Protection Method of Plaintext and Ciphertext in Optical Transmission Network of University Data Cloud Network
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％.
