Simplified Data Encryption Standard (S-DES) is a simple version of the DES Algorithm. It is a block cipher that takes a block of plain text and converts it into ciphertext. It takes a block of 8 bit. It is a symmetric key cipher, they use the same key for both encryption and decryption. We take a random 10-bit key and produce two 8-bit keys.
