摘要: 针对现有群密钥分配方案中存在的抗授权侵犯能力弱的问题,提出一种基于角色授权的群密钥分配方案,通过为群成员引入角色授权的接入约束,提高了抗授权侵犯的能力,减少了群在授权侵犯下的安全威胁范围。通过与其他群密钥分配方案的比较,显示该方案具有安全性和可用性。

Abstract: 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.

Key words: role authorization, Ad Hoc network, group key distributed, authorization assault
