Key agreement in dynamic peer groups
WebThe key challenge of dynamic peer communication is how to realize secure and efficient group key management. A two rounds key agreement protocol for dynamic peer group (DPG) is proposed in this paper. The protocol, which was obtained by combining the ElGamal encryption scheme with the ElGamal signature scheme, is efficient and simple. Web1 jul. 2008 · Dynamic peer groups require not only initial key agreement (IKA) but also auxiliary key agreement (AKA) operations such as member addition, member deletion and group fusion.

WebTo efficiently maintain the group key in a dynamic peer group with more than two members, we use the Tree-Based Group Diffie-Hellman (TGDH) protocol proposed in [11]. Each member maintains a set of keys, which are arranged in a hierarchical binary tree. We assign a node ID v to every tree node. For a given node v, we associate a secret (or ... Webmodate more than two members in a dynamic peer group. In Section 3, we present three interval-based distributed algo- rithms to reduce the computation and communication costs for maintaining the group key in a dynamic peer group. We also carry out mathematical analyses to quantify sys- tem performance according to given performance metrics
WebIn 1996, Steiner et al. [31] gave a group key agreement protocol based on the natural extension of the DH key agreement protocol. Later, in 1998, Steiner et al. [32] gave a new approach to group key agreement. They studied the problem of key agreement in dynamic peer groups(DPG). Also, Bresson et al.

WebThus, multiple key agreement protocols can overlap in time and cause instability unless significant amount of state is kept within the key agreement protocol implementation.) For this reason, there is no particular benefit to building key agreement on top of EVS semantics. The issues surrounding implementation of key agreement in dynamic peer ...
