A Survey on Satellite Network Security
A Survey on Satellite Network Security
Ma Ting G0902682F mati0004@ntu.edu.sg Abstract
Security is an important concern in satellite multicast communications. Due to its highly dynamic broadcast nature, the multicast systems generally have a large number of terminal members with frequent join-leave characteristic. Therefore, the satellite networks face significant security challenges, such as eavesdropping and Denial of Service (DoS). What is more, satellite systems are resource-constrained, particularly in the areas of limited transmission power, processing and switching capability for satellites. And satellite channels themselves experience high bit-error rates, which can result in packet loss and loss of security synchronization.
In the review of recently updated Digital Video Broadcasting-Interaction Channel for Satellite Distribution Systems (DVB -ICSDS) [1] and some satellite security literatures, we mainly survey satellite security on key management, key distribution and DoS attack prevention techniques.
Key Words: satellite system; key management; key distribution; DoS attack

1. Introduction
Satellite multicast applications now plays a significant role in our daily life. Satellite systems can reach any location on the earth and provide broadcasting services from one transmitter to many receivers. Since born in 1965, satellite communications have developed promising tele-communication and digital video broadcasting via satellite services all over the world. Up to now, especially with the advent of Fourth Generation (4G) of wireless communications
