A New Secure Group Key Management Scheme for Ad-hoc Networks Liu Zhiyuan Mao Shengli (College of Computer Science and Technique ,Huazhong University of Science and Technology,Wuhan Hubei 430076) (School of Computer Science and Technology, Huangshi Institute of Technology ,Huangshi Hubei 435003 ) Abstract: Based on the verifiable threshold secret sharing mechanism, a novel group key management scheme named DVGKM (Distributed Verifiable Group Key Management) is proposed in this paper, in which each entity holds a secret share and multiple entities in a local neighborhood can jointly update the group key.
