基于USB KEY的CSP实现

Implementing CSP Base on USB KEY

CSP是目前应用最广泛的PKI密码接口。CSP终端用户通过Windows提供的CryptoAPI公共接口访问密码函数,而不需要去关心密码运算的具体实现。USB KEY具有使用方便、安全性高、运算能力强等特点,是实现PKI密码运算的理想设备。用户可以通过调用动态库来使用USBKEY的加密运算功能,从而实现CSP所需要的PKI密码函数。本文从CSP的技术原理出发,结合USB KEY的功能特点,深入讨论了如何使用USB KEY实现CSP的功能。

CSP is the most generally cryptographic interface of PKI.The end user can use the cryptographic function supplied by CSP through the Windows CryptoAPI,the implement of cryptographic operation is careless.USB KEY possesses the characteristics such as easy to operate,hfgh security,powerful operation,is the perfect device of implementing PKI cryptographic operatfon.This paper introduces the theory of CSP,also the functfon of USB KEY, dfscuss the CSP fmplement base on USB KEY.
