The advent of conference mobile call demands the security communication between end users. However, currently there is no efficient secure end-to-end protocol exists for conference mobile call. This slows down the steps of conference communication. In this paper a secure end-to-end protocol for remote conference is designed base on previous experts work, which is one-to-one end-to-end protocol. In...
Considered the especial requirements to protect the identity of the user who join a networks conference, a secure and anonymous conference authentication scheme was proposed which is based on 0/1 knapsack problem. The security of authentication and anonymity was analyzed in detail. It is showed that the proposed scheme could not only achieve authentication securely but also has a secure anonymity,...
An effective group key agreement protocol is important for group-oriented applications. Some key tree approaches have been proposed by other researchers. The rekey cost of some of them scales with the logarithm of the group size for a join or leaving request, in which TGDH (tree based group Diffie-Hellman) is considered as one of the most effective and secure protocols. But the rekey cost is still...
