WebThe Cipher Text that you get after encrypting a Message depends on what key you use. Alice wants to send a message to Bob. Alice and Bob need to have agreed on which key they are going to use. Note: This example does not show perfect secrecy. e.g. A cipher text of (X,Z) reveals that the message must have been (Yes,No). WebTraditional Ciphers. In the second chapter, we discussed the fundamentals of modern cryptography. We equated cryptography with a toolkit where various cryptographic techniques are considered as the basic tools. One of these tools is the Symmetric Key Encryption where the key used for encryption and decryption is the same.
