Bit slicing was common with early processors, notably the AMD (Advanced Micro Devices) … WebIt is a simplest form of substitution cipher scheme. This cryptosystem is generally referred to as the Shift Cipher. The concept is to replace each alphabet by another alphabet which is ‘shifted’ by some fixed number between 0 and 25. For this type of scheme, both sender and receiver agree on a ‘secret shift number’ for shifting the alphabet.

In this type of cipher, the information to be encrypted (known as plaintext) is divided into sections called blocks. AES uses a 128-bit block size, in which data is divided into a four-by-four array containing 16 bytes. Since there are eight bits per byte, the total in each block is 128 bits.
