Abstract
A method of supporting a security for a multicast communication is provided in a mobile station. The mobile station shares an MAK with a base station, derives a prekey based on a first parameter including the MAK, and derives a multicast security key including an MTEK based on a second parameter including the prekey, and decrypts a multicast traffic using the multicast security key.
