Webb27 sep. 2024 · Simplified Data Encryption Standard (S-DES) is a simple version of the DES Algorithm. It is similar to the DES algorithm but is a smaller algorithm and has fewer parameters than DES. It was made for educational purposes so that understanding DES would become simpler. It is a block cipher that takes a block of plain text and converts it … WebbWhile these ciphers are no longer used, they are simple enough to perform operations by hand while demonstrating important concepts used in the design of most symmetrical ciphers used today. ...
