摘　　要：针对信息安全问题,提出了一种网络密码机系统。以高性能的硬件加密芯片SafeXcel-1141和PowerPC 405EP嵌入式CPU为核心,实现了一种新的硬件加密的系统。介绍了网络密码机的软、硬件的设计,并着重讲述了如何在软件系统中整合硬件加密资源,实践证明性能上有了很大的提高。For the problem of information security, a system of network cipher machine was designed. We mainly use high-performance hardware-crypto-chip, SafeXcel-1141 and an embedded CPU, PowerPC 405EP,and thus realize a new software-encryption system. The paper introduces the software and hardware design of the network cipher machine, and emphasizes how to merge the resources of the crypto-chip with the software system. The result has proved that they do a much better job in encryption.
