Abstract


Due to the characteristics of multicast communications and IP multicast model, a multicast network have a greater security risk than unicast network in the presence of the security aspects of a lot of lack of secure multicast become a hot issue in the research area of ??the current multicast. The Secure Multicast study involves two aspects: the control of the group members and the multicast data transmission. Existing IP multicast model IGMPv2, IGMP (Internet Group Management Protocol) management, mainstream version of the group members. IGMPv2 group members join and exit any restriction, any user can join a multicast group to send or receive multicast data. Multicast data transmission, the the existing multicast model did not take any security measures. Therefore, IP multicast communication are easy to access and transfer two phases were attacked. 863 project \species the new security multicast model, and the Linux kernel module programming techniques to achieve the model. New secure multicast model designed with the safety of the group management protocol (Group management protocol with security the abbreviation GMPWS) and the transport protocol (End-to-End virtual circuit-based transport protocol based on end-to-end VC, the abbreviation for the VCTP). The learn from the IGMPV2 framework in GMPWS redesigned join and leave multicast groups. Join a multicast group, the user must go through the group management server certification before they can join the multicast group, and get a set of keys. If it is the sender, the key is used to transmit data for encryption, if the receiving side, the received set of data is decrypted using the key. Leave a multicast group, the user must take the initiative to be sent to the group management server exit request. At the same time, the agreement also responsible for group key dynamically updated to guarantee forward multicast data security and after security. VCTP designed for multicast data transfer protocol, using end-to-end virtual circuit to transmit multicast data. The agreement, the node identification rely mainly on the port number and the virtual circuit number, use VC number instead of a multicast address, hidden multicast address, to ensure the security of the multicast group. VC structure can effectively guarantee the QOS demand, improve the reliability and stability of the multicast transmission. Based secure multicast end system is an important part of the new security multicast model prototype system. According to based secure multicast end system needs analysis, the system GMPWS VCTP resource management mechanism, can provide protection for members of the security access and secure transmission of the multicast data, to relieve the pressure of the core network to ensure the stability and reliability of the network. The management server of the end system and the group (Group management server) together to complete the secure transmission of the multicast and the core network, while ensuring the security of the multicast source and on the transmission link. The secure multicast end system-based goal is to make the multicast network is safe, reliable, controllable, and ultimately enable multicast technology to meet the needs of rapid development of the Internet.
