WebDES is a symmetric-key block cipher that encrypts data in 64-bit blocks. It uses a fixed-length key of 56 bits, making it relatively easy to break using brute-force methods. The algorithm uses a Feistel network, which divides the input data into two halves, processes them separately, and then combines them to produce the output. WebDES Weak Keys • DES uses 16 48-bits keys generated from a master 56-bit key (64 bits if we consider also parity bits) • Weak keys: keys make the same sub-key to be generated in more than one round. • Result: reduce cipher complexity • Weak keys can be avoided at key generation. • DES has 4 weak keys – 01010101 01010101 – FEFEFEFE ...
