Multicast is an efficient and natural way of communicating information via Internet, but its security is identified as one of the most important problems to solve for the successful deployment of group communication applications. First of all, in secure multicast group members must be able to verify that the data received is indeed sent by an authorized sender, and this is called dasiadata origin...
Anycast is a communication mode in which the same address is assigned to a group of servers and a request sent for a service is routed to the 'best" server. Because the group management and the routing protocol in the anycast are not so mature, there are distinct and significant security vulnerabilities in both the anycast model including denial of service, theft of service, eavesdropping, and...
Multicast authentication is a vital component in secure group communications, but authenticating real-time multicast streams over lossy channels or unreliable networks is very difficult due to the packet losses, expensive overheads and high delays. So this paper introduces a novel approach to multicast authentication based on LMCM (Layered Multiple Chaining Model). By the theoretical analyses, it...
Anycast is a new communication mode in the standards of IPV6. A host can communicate with the "nearest" member in the destination group through anycast. Because the group management and the routing protocol in the anycast are not so mature, when communicating it is easy to be utilized by some attacks such as masquerading and denial of service, etc. Utilizing the correlative secure technology...
