摘要
随着VPN安全网关广泛应用于企事业单位,高安全性、高可靠性和高性价比是提高VPN网关竞争力的重要手段。研究了Motorola PowerPC通信处理器MPC8xx处理器,并根据VPN网关的具体要求,设计了性价比较高的硬件平台;针对MPC855T的特点和结构,提出了基于MPC855T硬件平台VPN网关的技术设计方案,并简述了硬件加密模块的实现方法。
With widely applying of VPN security gateway in enterprises and govemment units, the high security, the high reliability and the high trust worth are to the important method of enhancing the competitiveness. The MPCSxx processor of Motorola PowerPC com- munication processor is studied, and according to the specific request of VPN gateway, has designed hardware platform which has more high performance-to-price ratio; In view of the characteristic and the structure of MPC855T, the design schema of VPN gateway based on the hardware platform of MPC855T is proposed, and the implementation method of the hardware encrypt the module is summarized.
