This paper presents the design and implementation of key management architecture
for secure multimedia audio streaming to multicast receivers. It describes the methods and
techniques which are used in making a multicast multimedia streaming application
(MMKM). It also highlights the security issues involved, implementation of Multimedia
Internet Keying (MIKEY), integration with Secure Real time Transport Protocol (SRTP)
and then using it for transmitting real time multimedia data in Multicast environments. The
main emphasis has been on security rather than on data transmission and compression. In
case of multimedia, only audio data is chosen.
