摘要
无线局域网安全标准的发展对AP(accesspoint)实现提出了更高的要求。本文通过分析几种新型WLAN安全标准的特点,设计了一种基于Samsung公司的S3C2510微处理器的硬件系统,用于实现WLAN的安全接入。针对AP系统密码运算能力不够的瓶颈,在硬件系统中增加了密码协处理器。该密码协处理器用FPGA芯片实现,具有良好的可扩展性,较好的解决了这个问题。
With development of Wireless local area network security standard, higher performance AP must be realize. This paper design a kind of hardware system based on Samsung Inc.'s S3C2510 microprocessor, aimed at security access about WLAN. In this system we crypto coprocessor is used in order to improve cipher computation performance. The implementation of crypto microprocessor is based on FPGA, so it has excellent extensibility and solves cipher computation ability's drawback existed in general AP systems.
