| 摘 要： | 为了保证某些领域的嵌入式计算机系统的信息安全,提出了系统多方式自毁功能模块。基于关键领域计算机的自毁功能,提出多级自毁策略。在一个三模冗余加热备份模块的模型机的基础上,设计并实现了多策略的自毁安全子系统。通过软硬件结合,采取数据、程序、电气等3种自毁方式。通过测试,能够达到预期效果。

| Abstract: | This paper presents a self-destruct function model to ensure the security of embedded computer systems.The multi-level self-destruct policy is given by the computer self-destruct function placed in key fields.A self-destruct function subsystem with multiple strategies was implemented based on a triple modular redundancy hot backup model.Three self-destruct methods for data,programs,and electrical are combined in software and hardware.Tests show that the expected self-destruct effect is realized. |
