为提高无线传感器网络中访问控制的安全性和公平性，引入角色思想，提出一种改进的访问控制方案。利用角色授权机制和智能卡认证模式相结合的方法，提高基站密钥的安全性和会话密钥的公平性，同时改善系统权限管理的灵活性和复用性。通过相互认证策略使通信双方检测并拒绝不正确或不完整的交换信息。理论分析结果表明，与 Das 方案相比，该方案在通信成本方面减少了384 bit，并具有合理的计算成本和相近的存储成本，安全性更高。

In order to improve the security and fairness of access control in Wireless Sensor Network(WSN) and introduce role theory, this paper proposes an improved role-based access control scheme in WSN. Combining the role authorization with the smart card authentication model, this scheme improves the security and the fairness of the session key as well as the flexibility and reusability of system permissions management. Mutual authentication is provided for two parties to detect and reject incorrect or incomplete exchange information. Through theoretical analysis and evaluation, it proves that this scheme reduces 384 bit in communication costs and has a reasonable calculation cost as well as analogical storage cost compared with Das scheme, and it is more secure.
