摘要
随着信息时代的发展,计算机得到了广泛应用,计算机中的信息安全成为一个极为重要的问题;针对计算机的性息泄漏问题,设计了基于RFID技术的计算机身份认证系统;系统由USB-Lock和无线Key两个硬件设备和软件组成,当无线Key处在USB-Lock的感应区域时,双方保持通信,计算机处于可用状态;当无线Key超出USB-Lock的感应区域时,双方通信中断,计算机进入不可用状态,当用户回到计算机附近时,双方通信得到恢复实现计算机信息保护。
As the information age develops, the computer has come into widespread use and the safety of information in the computers has become an extre important problem. Focusing on the problem of information disclosure, the computer identification system based on the RFID technology is designed. The system is composed of two hardware devices which named USB--Lock and wireless Key. When the wire- less Key locates in the USB--Lock＇ s effective range, the two sides can be able to maintain wireless link, the computer is in the operating status at this time. When the wireless Key is outside the USB--Lock＇ s effective range, the communication fails and the computer is out of the operating status. When the user returns into the effective range with the wireless Key, the communication between them will be estab- lished again so that the system can protect the information in the computers.
