Recently, in Journal of Security and Communication Networks (5(12):1363-1374, DOI: 10.1002/ sec.429), Wang et al. proposed a group key distribution scheme with self-healing property for wireless networks in which resource is constrained. They claimed that their key distribution scheme satisfies forward security, backward security and can resist collusion attack. Unfortunately, we found some sec...

Group key management is an important functional building block for any secure multicast architecture. Thereby, it has been extensively studied in the literature. In this paper we present relevant group key management protocols. Then, we compare them against some pertinent performance criteria. Keywords—Multicast, Security, Group Key Management.

Major shortcomings in a recently published group key establishment protocol are described. These shortcomings are sufficiently serious that the protocol should not be used.

Now-a-days Internet has become the common media of communication. Many group communication application such as pay-per-view, stock quote distribution, voiceand video-conferencing, white-boards, distributed simulations, and replicated servers of all types, etc can easily be conducted on the Internet. For conducting such applications, group key is often needed, which can be established by group k...

Contributory group key management schemes are popularly used for dynamic peer group communications in collaborative environments. Previous contributory group key management schemes require every group member to perform a number of expensive Diffie-Hellman operations whenever the group membership changes. This is not always affordable for devices in resource-constrained networks. In this paper, ...

Secure group key distribution and efficient rekeying is one of the most challenging security issues in sensor networks at present. In this paper, Latin square is firstly used to construct orthogonal arrays in order to obtain t-packing designs quickly. Based on cover-free family properties, t-packing designs are adopted in key predistribution phase. Then based secure key-shared method, the pre-d...

The self-healing group key distribution with revocation can deal with the session key distribution problem for secure group communication over an unreliable wireless network, with the capability of resistance to the packet loss and the collusion attack. However, since previous self-healing group key distribution schemes are restricted to m sessions, they will be reset frequently, which leads to...

Scalable group key management solutions are crucial for supporting Internet applications that are based on a group communication model. Many solutions have been proposed and of these the most efficient and scalable ones are based on logical key hierarchies (LKH) with symmetric keys organized in a tree. However, these solutions centralize trust in the group controller and make it an attractive a...
