	abstract = {This paper proposes a design for key management for secure multicast in hybrid satellite networks. Communication satellites offer an efficient way to extend IP multicast services for groups in wide-area networks. In order to be commercially viable, the multicast traffic should be accessible only to paying subscribers. Access control can be achieved by data encryption. This requires secure and efficient methods to generate, distribute and update the keys. Most current key management protocols do not scale well when applied to large dynamic groups in wide-area networks. This paper attempts to solve the above problem for groups in a hybrid network that is composed of terrestrial Ethernet LANs interconnected by ATM-based satellite channels. We investigate current group key management protocols, and design a framework for secure and scalable key management for the multicast routing architecture in the satellite network. The proposed framework is presented in detail, alongwith analysis and simulation results.},

	abstract = {The demand for internet access has been characterized by an exponential growth. The introduction of high-speed satellite communications systems providing direct-to-home internet is a response to this increasing demand. However such systems use geo-synchronous satellites and suffer from high latency. Currently, the most popular application layer protocols for the World Wide Web (WWW) are HTTP/1.0 and HTTP/1.1. Since HTTP is a request-response protocol, there are performance issues with using it over high-delay links such as links involving Geo-synchronous Earth Orbit (GEO) satellites. Such usage leads to severely increased user perceived latency which makes "internet browsing" a cumbersome experience. In this paper we investigate this problem and analyze a mechanism to reduce this user-perceived delay.},
