基于强双因子身份认证的企业银行安全系统

The design of safe system in the enterprise bank based on CA with the double strong factors

基于单因子的身份认证技术,不能满足对安全性要求较高的应用系统要求,因为操作员代码+口令方式容易被破解,而采用强双因子(用户+PIN值和物理存储介质)认证方式将有效地提高应用系统对安全性的要求.根据某企业银行应用系统的实例要求,以强双因子身份认证技术为基础,提出了一种可普遍推广应用的高安全应用级别的实现方法.

The CA technique with the single factor is not satisfactory with the higher safety request of the application system because its user code ＋ password is easy to be decoded, but the safety of application system will be increased by means of CA method with double strong factors（user code ＋ the PIN value and physical memory medium）. This paper presents the general realization method of the CA technique with the double strong factors according to the demand for the higher safety of an enterprise bank application system.
