Summarization to Security in Mobile Ad-hoc Networks Feng Kun Duan Li Cha Hao
(Navy University of Engineering, Department Of Information Security，Wuhan Hubei，430033) Abstract：Compared with the traditional wired networks，Mobile ad-hoc networks have many characteristics which make it has security questions in each layer and easily be attacked. For its different characteristics from the wired networks, it will face with the new challenge in security. In this paper, research based on the requests of the security of Mobile ad-hoc networks, we focus on the popular attacks to the Mobile ad-hoc networks. And primarily discuss on the routing security and key management of mobile Ad-hoc network..
