Abstract:
Secure wireless network data transmission requires not only encryption
and decryption algorithms, but also the support of secure key distribution protocol. A
key distribution protocol (KDP) distributes the key to the message bearer in a secure
and efficient manner. There is no secure key distribution protocol, even if the use of
a powerful encryption/decryption algorithm, the whole system will exist insecure
factors. The commonly used encryption/decryption algorithms are either based on
public key or private key. And the private key password system is fast, but the security
performance is poor. This paper discusses the security key distribution protocol in
wireless network, which can improve the security of the system.
安全的无线网络数据传输,不仅需要加密、解密算法,还需要有安全
的密钥分配协议的支持。一个密钥分配协议(简称 KDP)是将密钥以一种安全、
有效的方式分发给消息传递者。没有安全的密钥分配协议,即使使用了强有力
的加 / 解密算法,整个系统也会存在着不安全的因素。常用的加 / 解密算法或
是基于公钥,或是基于私钥(公钥密码系统有较好的安全性,但速度慢; 而私
钥密码系统速度快,但安全性能差)。本文探讨无线网络中安全密钥分配协议,
可提高系统的安全性。
