通过ad hoc无线网络发送安全消息 [英] send secure message through ad hoc wireless network

问题描述

在我的项目中，我需要有关ad hoc网络的安全通信协议的帮助，并且我想创建一个应用程序软件，该软件可以帮助两台或多台机器通过无线ad hoc网络进行安全的通信.

please i need help for my project about a secure communication protocol for ad hoc network,and i want to create an application software that can help two or more machines to communicate securely through wireless ad hoc network.

推荐答案

首先，即使有人在建立联系之前侦听该通信，该通信也是完全秘密的.许多人会说这在逻辑上是不可能的，因为他们需要第一次交换密码或类似的东西.如果您阅读有关公钥密码学的内容，则该论点有一个微妙的逻辑缺陷.请参阅:

http://en.wikipedia.org/wiki/Public-key_cryptography [ http://msdn.microsoft.com/en-us/library/system. security.cryptography.asymmetricalgorithm.aspx [ ^ ].

现在，您需要学习一些网络知识，并了解哪种网络方式更适合您的目的.我在过去的回答中概述了它们:
我如何将byte []发送到另一台PC [ ^ ]，
在局域网上与两个Windows应用程序进行通信. [^ ].

First of all, the communication can be perfectly secret even someone spies on the communication before people ever establish a contact. Many would say it is logically impossible, because they need to exchange passwords or something like that for a first time. This argument has a subtle logical flaw you are about to discover if you read about public-key cryptography. Please see:

http://en.wikipedia.org/wiki/Public-key_cryptography[^].

There are several well-know methods well implemented in .NET. Look for one of the asymmetric algorithm classes (RSA is the most usually used):

Now, you need to learn some networking and understand which way of networking is better for your purposes. I overview them in my past answers:
how i can send byte[] to other pc[^],
Communication b/w two Windows applications on LAN.[^].
