Group key distributed algorithm based on role authorization in Ad Hoc network
基于角色授权的Ad Hoc网群密钥分配算法

Ability of resisting authorization assault is weak for existed group key distributed scheme. A group key distributed algorithm based on role authorization was proposed. The algorithm improves ability of resist and depresses threat of security on authorization assault by importing role authorization restricted in access control for group. Comparing with the other alike schemes, the proposed scheme is secure and useable.
