Types of symmetric encryption included Data Encryption Standards (DES), a low-level encryption block cipher algorithm that converts plain text into blocks of 64 bits and converts them to ...

The algorithm is then numerically refined to use fixed-point arithmetic to reduce the complexity of the final hardware or software implementation. In hardware, constraining the integer or fixed-point ...
