一种改进的无线网络安全临时密钥完整性协议

Modified Temporal Key Integrity Protocol For Efficient Wireless Network Security

M. Razvi Doomun, KM Sunjiv Soyjaudah

摘要:

临时密钥完整性协议(TKIP)是IEEE TaskGroupi针对已经广泛部署的802.11硬件中存在的安全环路漏洞的解决方案。它是一组算法,包装WEP,以提供最佳可能的解决方案,给出设计约束,如CPU周期不足,WEP加密算法的硬连线和软件升级依赖。因此,TKIP的实施和优化比WEP更困难和更具挑战性。这项研究的目的是检查TKIP安全机制的成本和效益,并优化其实施,以减少安全开销,以获得更好的性能。我们提出了一种改进的TKIP(MoTKIP)与改进的数据包封装和解封装过程,大大减少了计算和数据包开销在经典的TKIP和优化总的无线网络吞吐率。

英文摘要:

Temporal Key Integrity Protocol (TKIP) is the IEEE TaskGroupi solution for the security loop holes present in the already widely deployed 802.11 hardware. It is a set of algorithms that wrap WEP to give the best possible solution given design constraints such as paucity of the CPU cycles, hardwiring of the WEP encryption algorithm and software upgrade dependent. Thus, TKIP is significantly more difficult and challenging to implement and optimise than WEP. The objective of this research is to examine the cost and benefit of TKIP security mechanisms and optimise its implementation to reduce security overhead for better performance. We propose a modified TKIP (MoTKIP) with improved packet encapsulation and decapsulation procedure that reduces computation and packet overhead in classic TKIP substantially and optimises total wireless network throughput rates.
