New region-based group key management scheme in Ad hoc networks
基于地理区域的Ad hoc网络组密钥管理方案*

Ad hoc network has the characteristics of dynamic topology and openning of wireless transmission media, the network is vulnerable to security threats.This paper proposed an algorithm named MGDH for key agreement.Furthermore,put forward a scalable group key management scheme(RGKM) based on geographical region.The single point failure problem was solved due to independence of the trusted third party. By introducing the idea of reverse routing,decreased the traffic without security reduced, which was helpful to the realization of energy balance.
