無線分布式網絡的路由機制已經相當成熟，但無線的開放性、自組織網絡拓撲的不確定性以及無線設備資源的有限性為其安全性帶來了一定挑戰。本文針對無線自組織網絡的這些特點，提出了一種安全的無線分布式網絡模型SAM-DN，引入了分布式認證中心進行密鑰協商。并采用ECC 代替了傳統的RSA加密算法。這些新機制配合SAM-DN 自身的特點，使得該模型能更好適應無線分布式網絡帶寬、計算能力及存儲空間的有限資源。

Research on Authentication and Key Agreement for Wireless Distributed Network
Lu Hai-feng1，Huang Ben-xiong2，Mo Yi-jun3 （Department of Electronic and Information, Huazhong University of Science and Technology, Wuhan 430074, China） Abstract: The route mechanism of wireless distributed network has developed maturely, but the security is still unsolved due to the openness, mobility and resource limitation. This paper gives out a security wireless distributed network model which is called SAM-DN, introduces distribute certification authority to intermediate key agreement, and uses ECC to take instead of traditional RSA encryption arithmetic. All above novel mechanisms make the SAM-DN adapt well to the limited bandwidth, computation capacity and storage.
