WebIn cryptography, a permutation box (or P-box) is a method of bit-shuffling used to permute or transpose bits across S-boxes inputs, retaining diffusion while transposing. [1] An example of a 64-bit "expansion" P-box which spreads the input S-boxes to as many output S-boxes as possible. WebCryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce. Modern cryptography techniques include algorithms and …
