Security of satellite data is becoming an important issue. The DVB (TV broadcasting) Conditional Access system used in satellite broadcasting has however been surrounded by controversy for many years due to the spread of counterfeit smart cards, and this paper examines the weaknesses of current DVB-S security. We provide an alternative solution to secure multicast services over satellites using IPSEC and a group key management system called GSAKMP.
