無線分布式網(wǎng)絡(luò)認(rèn)證及密鑰協(xié)商機(jī)制研究

無線分布式網(wǎng)絡(luò)的路由機(jī)制已經(jīng)相當(dāng)成熟，但無線的開放性、自組織網(wǎng)絡(luò)拓?fù)涞牟淮_定性以及無線設(shè)備資源的有限性為其安全性帶來了一定挑戰(zhàn)。本文針對無線自組織網(wǎng)絡(luò)的這些特點，提出了一種安全的無線分布式網(wǎng)絡(luò)模型SAM-DN，引入了分布式認(rèn)證中心進(jìn)行密鑰協(xié)商。并采用ECC 代替了傳統(tǒng)的RSA加密算法。這些新機(jī)制配合SAM-DN 自身的特點，使得該模型能更好適應(yīng)無線分布式網(wǎng)絡(luò)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.
