移动Ad hoc网络中保护OLSR的试验床实现
A Testbed Implementation for Securing OLSR in Mobile Ad hoc Networks
摘要：
越来越多地要求当代个人计算设备是便携式和移动的，从而使得用户能够无线接入有线网络基础设施和服务。这种移动计算和通信的方法只适用于具有一致基础设施的情况。有许多情况下，这些要求没有得到满足，如发展中国家，农村地区，自然灾害和军事冲突，仅举几例。一种实际的解决方案是使用经由无线介质互连的移动设备来形成被称为移动自组织网络（MANET）的网络，并且提供通常在有线网络中发现的服务。由于通信链路的无线性质，移动自组网中的安全性是一个至关重要的问题。此外，由于缺乏中央管理，安全问题与传统网络不同。为了本文的目的，我们使用了“WMN测试床”，以实现安全路由的移动自组网。密码学的使用是在通信中保护数据的有效方法，但一些密码算法不如其他算法有效，并且需要更多的处理能力，这对移动台是不利的。在这篇文章中，我们已经评估了不同的加密方法，以确保OLSR（优化链路状态路由）协议，提供一个基础的研究。我们总结了一系列的性能评估结果不同的加密和哈希方案的文件。我们的研究结果清楚地表明，用于身份验证和加密的最有效的算法组合分别是SHA-1和AES。使用这种组合将大大减少网络上的处理时间和延迟，从而创建一个高效的交易，以满足资源限制和安全要求。
英文摘要：
Contemporary personal computing devices are increasingly required to be portable and mobile enabling user's wireless access, to wired network infrastructures and services. This approach to mobile computing and communication is only appropriate in situations where a coherent infrastructure is available. There are many situations where these requirements are not fulfilled such as; developing nations, rural areas, natural disasters, and military conflicts to name but a few. A practical solution is to use mobile devices interconnected via a wireless medium to form a network, known as a Mobile Ad-hoc Network (MANET), and provide the services normally found in wired networks. Security in MANETs is an issue of paramount importance due to the wireless nature of the communication links. Additionally due to the lack of central administration security issues are different from conventional networks. For the purposes of this article we have used the "WMN test-bed" to enable secure routing in MANETs. The use of cryptography is an efficient proven way of securing data in communications, but some cryptographic algorithms are not as efficient as others and require more processing power, which is detrimental to MANETs. In this article we have assessed different cryptographic approaches to securing the OLSR (Optimised Link State Routing) protocol to provide a basis for research. We conclude the paper with a series of performance evaluation results regarding different cryptographic and hashing schemes. Our findings clearly show that the most efficient combination of algorithms used for authentication and encryption are SHA-1 and AES respectively. Using this combination over their counterparts will lead to a considerable reduction in processing time and delay on the network, creating an efficient transaction moving towards satisfying resource constraints and security requirements.
