干线信息保护设备同步概率自动测试技术

Automatic Test Scheme for Cipher Synchronization Trunk Information Protection Device

干线信息保护设备用于保护干线链路信息的安全性，其基本的信息保护手段是加密技术。同步概率是干线信息保护设备的一个重要技术指标，也是设备验收和测评的必测项目。但是该指标的测试一直是一个棘手的问题，传统上基本都是采用基于设计理论分析或专用的测试方法，但是这两种方法都具有较大的缺陷。文中提出的干线信息保护设备同步概率自动测试技术则很好地解决了该问题。

Cipher synchronization probability is a very important specification for trunk information protection device. It＇ s also a basic test item when trunk information protection device is tested or accepted although it＇ s very difficult to test this specification. Traditional test methods are theoretic analysis or special-use methods, which are of comparatively serious deficiency. Automatic test scheme for cipher synchronization probability of trunk information protection device proposed in this paper solves this problem successfully.
