D-VKT: A Scalable Distributed Key Agreement Scheme for Dynamic Collaborative Groups
Summary :
Key agreement for collaborative groups has become an increasingly popular research area. However, most of previous work requires each member to not only maintain the whole key tree structure whose size is O(N), where N is the size of group, but also involve rekeying operation upon each membership change, resulting in high costs in terms of storage, communication and computation and thus suffers from poor scalability. In this paper, we propose a scalable Distributed and collaborative group key agreement scheme using a Virtual Key Tree (D-VKT). Each group member in D-VKT only reserves and maintains partial information of the whole key tree structure with requirement of O(log N). Furthermore, a distributed tree balancing algorithm is presented to keep the whole key tree as balanced as possible for rekeying efficiency. In addition, a distributed group batch rekeying protocol is proposed to further reduce the computation and communication workload of group rekeying in a highly dynamic environment. The experiment results demonstrate that D-VKT can scale to large and dynamic collaborative groups.

In this paper, we propose a scalable Distributed and collaborative group key agreement scheme using a Virtual Key Tree (D-VKT). Each group member in D-VKT only reserves and maintains partial information of the whole key tree structure with requirement of O(log N). Furthermore, a distributed tree balancing algorithm is presented to keep the whole key tree as balanced as possible for rekeying efficiency. In addition, a distributed group batch rekeying protocol is proposed to further reduce the computation and communication workload of group rekeying in a highly dynamic environment.

AB - Key agreement for collaborative groups has become an increasingly popular research area. However, most of previous work requires each member to not only maintain the whole key tree structure whose size is O(N), where N is the size of group, but also involve rekeying operation upon each membership change, resulting in high costs in terms of storage, communication and computation and thus suffers from poor scalability. In this paper, we propose a scalable Distributed and collaborative group key agreement scheme using a Virtual Key Tree (D-VKT). Each group member in D-VKT only reserves and maintains partial information of the whole key tree structure with requirement of O(log N). Furthermore, a distributed tree balancing algorithm is presented to keep the whole key tree as balanced as possible for rekeying efficiency. In addition, a distributed group batch rekeying protocol is proposed to further reduce the computation and communication workload of group rekeying in a highly dynamic environment. The experiment results demonstrate that D-VKT can scale to large and dynamic collaborative groups.
