If a plaintext always produced the same ciphertext, then an attacker could make a dictionary of different observed ciphertexts and know when the same plaintext was being repeated, which violates the confidentiality property desired from the protocol. -Ben On 07/28/2016 06:19 AM, R-D intern wrote: Hello, I am using ECDSA-ECDHE-AES-SHA cipher suite for client -server security.I tried understanding the mechanism handshake mechanism. What still quizzes me is ; communication between a specific client -server for a specific session generates different encrypted text for the same plain text message. What leads to this? Can anybody elaborate? Please reply.
