Abstract

Wireless communication adapters in mobile nodes form an ad hoc network without the need for any fundamental network infrastructure. Nodes in MANETs use radio signals with a finite range to communicate making it possible for any intermediate node to intercept the communication. Also the frequently changing topology, with high susceptibility to physical compromise along with the node's limitations in terms of energy resource, storage device and CPU form a tremendous challenge in providing security to MANETs. Unlike wired networks, there is no central infrastructure, which paves way for new challenges as services provided by central entities is now to be ensured by the mobile nodes in the network itself. As a result, there is no definitive form of defense and a comprehensive security solution should encompass avoidance, detection and reaction along with sought-after network performances. This paper focuses on the prevention/proactive approach of securing MANETs using NTRU (Nth degree truncated polynomial ring), to secure end-to-end communication through data encryption during data transmission. NTRU is Lattice-based cryptography, which is known to be resistant to quantum attacks. We assume a clustered MANET environment i.e. the mobile nodes have an efficient cluster-based routing algorithm deployed which gives us the list of clusters available in the environment along with its cluster heads and competent routing between them. The proposed technique provides data encryption using NTRU between cluster heads.
基于点阵的manet安全数据传输
移动节点中的无线通信适配器无需任何基础网络基础设施即可形成自组织网络。manet中的节点使用有限范围的无线电信号进行通信,使得任何中间节点都可以拦截通信。此外,频繁变化的拓扑结构易受物理危害,加上节点在能源、存储设备和CPU方面的限制,为manet的安全提供了巨大的挑战。与有线网络不同,没有中央基础设施,这为新的挑战铺平了道路,因为中央实体提供的服务现在由网络中的移动节点本身来保证。因此,没有确定的防御形式,一个全面的安全解决方案应该包括避免、检测和反应,以及受欢迎的网络性能。本文重点研究了利用NTRU (n度截断多项式环)保护manet的预防/主动方法,在数据传输过程中通过数据加密来保护端到端通信。NTRU是一种基于格子的加密技术,它可以抵抗量子攻击。我们假设一个集群的MANET环境,即移动节点部署了一个高效的基于集群的路由算法,该算法为我们提供了环境中可用的集群列表,以及集群头和它们之间的有效路由。该技术利用簇头之间的NTRU提供数据加密。
