摘　　要：针对USB存储设备身份认证机制容易被旁路,数据安全得不到有效保证的问题,文章给出了安全USB IP核结构,设计了USB系统的身份认证协议,实现了在硬件接口层响应主机端身份认证请求的安全USB IP核。结果表明,该安全USB IP核能够为USB设备上层功能层提供统一的身份认证服务,安全性高。The data security in the USB storage device can not be properly guaranteed clue to the problem that the identity authentication mechanism of the USB device can be easily bypassed. A secure USB IP core architecture is proposed in this paper, and an identity authentication protocol which is suitable for USB communication system is designed. Furthermore, the secure USB IP Core is implemented which can respond to the host identity request at bus interface level. Experimental results demonstrate that the secure USB IP core can provide unified identity authentication service for the USB device＇s function level and is of high security.
