USBKEY软硬件结合的CSP设计及实现

USB KEY因其小巧方便、安全性高等优点在网络安全中的应用越来越广泛。如今它不仅仅是数字证书的重要存储介质,USBKEY还在Windows系统中用作为加密服务提供体CSP(Cryptographic Service Provider)。这样,通过Windows的CryptoAPI,USB KEY提供的CSP就完成各种网络安全应用。在深入分析微软加密体系结构以及CSP原理的基础上,详细介绍了USB KEY上CSP的设计与开发方法。

Design and Implement of USBKEY CSP Combining Software and Hardware

USB KEY is using more and more widely in the network security because of its small size and higher security level providing. On present, it not only works as the storage device for digital certificates, but also provides Cryptographic Service Provider which could be used in the Microsoft Windows OS. Thus the CSP which USB KEY provides could implement many cryptography applications through the CryptoAPI of Windows. The architecture of Cryptography System in Windows OS and the principle of CSP are analyzed, introduced the design of CSP which bases on USB KEY, and described its developing method.
