基于单径路由的基础设施网络数据安全性研究

Improving Data Security in Infrastructure Networks Based on Unipath Routing

摘要:

基础设施网络是一个自组织网络,它使用无线链路的接入点(AP)连接一个节点与另一个节点。这些节点可以在不使用ad hoc的情况下进行通信,相反,这些节点形成任意拓扑(BSS/ESS),其中这些节点扮演路由器的角色。虽然基础设施网络的效率很高,但它们非常容易受到安全攻击。通过网络检测/预防这些攻击是一项极具挑战性的任务。提出了许多解决方案来在基础设施网络中提供认证、机密性、可用性、安全路由和入侵避免。在这种动态变化的网络中提供安全性是一项艰巨的任务。为了设计有效的解决方案,还应考虑基础设施网络的特点。在本研究中,我们重点关注基于多路径路由的基础设施网络中有效提高流传输机密性。为了提高传输数据的机密性,我们利用基础设施网络中节点之间存在的多条路径,并借助接入点。在这种方法中,原始数据被分割成包,并通过接入点转发。然后,加密的数据包在发送方和接收方之间存在的不同的不相交路径中转发。即使攻击者成功获得一个或多个传输的数据包,重建原始消息的概率也很低。

英文摘要:

An infrastructure network is a self-organizing network which uses Access Point (AP) of wireless links that connecting one node with another. These nodes can communicate without using ad hoc, instead these nodes form an arbitrary topology (BSS/ESS) in which these nodes play the role of routers. Though the efficiency of Infrastructure networks is high, they are highly vulnerable to security attacks. Detecting/Preventing these attacks over the network is highly challenging task. Many solutions are proposed to provide authentication, confidentiality, availability, secure routing and intrusion avoidance in infrastructure networks. Providing security in such dynamically changing networks is a hard task. Characteristic of infrastructure network should also be taken into consideration in order to design efficient solutions. In this study, we focus on efficiently increasing the flow transmission confidentiality in infrastructure networks based on multi-path routing. In order to increase confidentiality of transmitted data, we take advantage of the existence of multiple paths between nodes in an infrastructure network with the help of Access Point. In this approach the original data is split into package and are forwarded through access point. The encrypted packets are then forwarded in different disjoint paths that exist between sender and receiver. Even if an attacker succeeds to obtain one or more transmitted packets, the probability of reconstructing the original message is very low.
