摘　　要：针对紧急情况下防止敏感信息泄漏的问题,研究一种实时触发的敏感数据安全销毁系统.介绍了该系统的总体结构设计;设计一种基于动态消息截止期的总线通信调度器;设计一种无线IP传感器,可解决移动设备的安全监控问题;提出基于内存映射文件技术的文件覆写算法并采用CAN总线和数据销毁技术实现了一个原型系统.实验结果表明该原型系统能实时触发数据销毁程序使受控设备在紧急情况下安全终止,且被销毁的数据具有不可恢复性.To solve the problem how to prevent the sensitive information from leaking when an emergency occurs, a real time sensi- tive data safe destruction system is researched. The architecture design of the system is introduced; a field bus communication schedu- ler based on dynamic message deadline and a kind of wireless IP sensor which can solve the problem of monitoring mobile devices are designed; a file overwriting algorithm based on memory mapping file technology is proposed, and a prototype system which uses the technologies of CAN-bus and data destruction is realized. The experiment shows the prototype system can trigger the data destruction process in time to terminate them safely which protects their important data from leaking and the data which has been destroyed can not be recovered.
