In cryptography, Xenon is a block cipher designed in the year 2000 by Chang-Hyi Lee for the Korean firm SoftForum. The algorithm uses a key size of 128, 192, or 256 bits. It operates on blocks of 128 bits using a 16-round Feistel network structure with key whitening. Designed for speed, Xenon's round function doesn't use any S-boxes. The only operations it uses are XOR, addition, multiplication, and bit shifts.
