摘　　要：本文针对当前电子网络身份认证和数据的安全传输问题阐述了一种基于AT89C2051的USB安全钥的系统结构及相关技术。USB安全钥将密钥存储于USB硬件中,结合相应的加密算法。文中主要对USB安全钥端的软硬件设计进行了详细介绍。Nowdays, electronic network provides many conveniences to people by saving time, but it also brings some problems. In which, identity authentication and the safety of data transmission are the main problems. To solve them, a USB security key system based on AT89C2051 and related technologies are formulated in this paper. USB security key stores the cipher key in the USB hardware, and integrates the encryption algorithm. The software and hardware design of USB security key is also described in detail.
