MEGACAST MULTI2 IP core implements the MULTI2 encryption/decryption algorithms as specified by ISO9979/0009 algorithm register entry (ISO standard 9979 MULTI2).
MULTI2 is a block cipher, developed by Hitachi in 1988. It is designed for general-purpose cryptography, but its current use is encryption/decryption of high-definition terrestrial/BS/CS broadcasts in Japan.
