摘要


随着当前技术的不断进步,无线网络越来越普及。这些网站让用户可以“自由旅行”,从一个地方到另一个地方的过程中可以享受不中断的计算机网络服务。自组网,是无线网络的一部分,让无线网络的配置不需要访问点。目前正在开发无线自组网络技术,并且已经迅速成为我们生活中至关重要的一部分,因为它为移动用户提供了“随时随地”的网络服务。


无线自组网络可以动态地建立不依赖于任何已有的基础设施的网络服务,如公共密钥基础设施和中央管理通信。然而,这样缺乏基础设施特点的网络也使他们容易受到安全攻击。许多协议已经达成共识,计划建立一个基于人工中介沟通和正常的攻击模式的通信媒介,以获得高度的安全。其中一个是在之前的承诺协议和SHCBK协议中提出的对称的散列知识(a·w·罗斯科和长阮,2006)。协议设计的初衷是为了寻求优化的安全,人类可以获得一个已知数量的工作。本文提出了一种实现SHCBK协议的方法,来保护特设网络wi - fi。


Abstract


With present advances in technology, wireless networks are getting more popularity. These networks let the users the liberty to travel from one location to another without disruption of their computing services. The Ad-hoc networks, are the subset of wireless networks, let you the configuration of a wireless network without the require for access point. Technology under development for wireless ad hoc networks has quickly become a crucial part of our life since it provides “anytime, anywhere” networking services for mobile users.


Wireless ad hoc networks can be dynamically set up without relying on any pre-existing infrastructure, such as Public Key Infrastructure, and central management for communications. However, such infrastructure-less characteristic of the networks also makes them vulnerable to security attacks. Numerous protocols have been planned in order to attain a high degree of safety based on a mixture of human-mediated communication and an normal Dolev-Yao communication medium. One of which is the Symmetrised Hash Commitment Before Knowledge protocol or the SHCBK protocol ( A. W. Roscoe and Long Nguyen, 2006). The protocol design seeks to optimise the amount of security that the humans can attain for a known quantity of work. This dissertation presents an implementation of the SHCBK protocol for securing ad hoc networks over Wi-Fi

Introduction

A wireless ad hoc network is a de-centralized wireless network. The network is called ad hoc for the reason that each hop is ready to send onward data for other hop, and so the resolving that which of hops will send the data to the forward hops is dynamically established on the network connectivity. This is in dissimilarity to wired networks in which routers execute the duty of routing. It is also in difference to organize the wireless networks. In which a particular node recognized as an admission point manages communication among other nodes. All taking part parties in an ad hoc network have the same opinion to recognize and send onward messages, to and from each other. With this type of elasticity, wireless networks have the capability to form anyplace, at any occasion, as long as two or more wireless users are enthusiastic to have the communicate between them. Mobile nodes inside an ad-hoc network move from one location to another. However, finding ways to model these movements is not obvious. In order to evaluate an ad hoc network performance it is necessary to develop and use mobility models that accurately represent movements of the mobile nodes. In this paper we present performance evaluation of various entity mobility models in terms of the traveling patterns of mob论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
