WebAug 18, 2024 · Symmetric Key Encryption: Encryption is a process to change the form of any message in order to protect it from reading by anyone. In Symmetric-key encryption the message is encrypted by using a key and the same key is used to decrypt the message which makes it easy to use but less secure. WebFor example, the schemes DES and AES have block sizes of 64 and 128, respectively. Stream Ciphers In this scheme, the plaintext is processed one bit at a time i. one bit of plaintext is taken, and a series of operations is performed on it to generate one bit of ciphertext. Technically, stream ciphers are block ciphers with a block size of one bit.
