Abstract. Secure group communication systems have become increasingly important for many emerging network applications. An efficient and robust group key management approach is indispensable to a secure group communication system. Motivated by the theory of hyper-sphere, this paper presents a new group key management approach with a group controller GC. In our new design, a hypersphere is constructed for a group and each member in the group corresponds to a point on the hyper sphere, which is called the member's private point. The GC computes the central point of the hyper-sphere, intuitively, whose "distance" from each member's private point is identical. The central point is published such that each member can compute a common group key, using a function by taking each member's private point and the central point of the hyper-sphere as the input. This approach is provably secure under the pseudo-random function (PRF) assumption. Compared with other similar schemes, by both theoretical analysis and experiments, our scheme (1) has significantly reduced memory and computation load for each group member; (2) can efficiently deal with massive membership change with only two re-keying messages, i.e., the central point of the hypersphere and a random number; and (3) is efficient and very scalable for large-size groups.

Abstract-Various network applications require sending data onto one or many members, maintaining security in the large groups is one of the major obstacles for controlling access. Unfortunately, IP multicast is not providing any security over the group communication. Group key management is a fundamental mechanism for secured multicast. This paper presents relevant group key management protocols. Then, we compared them against some pertinent performance criteria. Finally, we discuss the new research directions in group key management.

“…Molva presented a framework for multicast security [Molva and Pannetrat 1999] that is based on Cipher Sequences (CS). A function f (S, a) is called Cipher Group (CG) if it has the following characteristics: there is a sequence of n elements, such as a 1≤i≤n ; and there is a sequence of n + 1 elements, such as S 0≤i≤n , where…”

Group communication can benefit from IP multicast to achieve scalable exchange of messages. However, there is a challenge of effectively controlling access to the transmitted data. IP multicast by itself does not provide any mechanisms for preventing nongroup members to have access to the group communication. Although encryption can be used to protect messages exchanged among group members, distributing the cryptographic keys becomes an issue. Researchers have proposed several different approaches to group key management. These approaches can be divided into three main classes: centralized group key management protocols, decentralized architectures and distributed key management protocols. The three classes are described here and an insight given to their features and goals. The area of group key management is then surveyed and proposed solutions are classified according to those characteristics.
