自毁技术对保护信息的私密性具有重要意义,是信息安全的终极手段。为实现分布式系统的自毁,建立了一种层次化自毁系统模型,基于粗糙集理论对自毁条件进行了判定,基于组件对自毁实现方法进行了设计。在此基础上,结合应用实例对自毁过程进行分析。结果表明,该方法有效地实现了分布式系统的不可恢复性自毁,自毁正确率和时间效率较高,具有较好的可行性和实用性。
Self-destruction technology is very important to the privacy of the information. To make a self-destruction on the distributed system,this paper established a hierarchical self-destruction system model. Based on the rough set theory,gave a method of self-destruction perception,and based on the component,designed a method of self-destruction implementation. By an instance,showed a description of a distributed system destroyed ruin,and destroyed the system completely. Through the analysis,it shows that this hierarchical self-destruction method has a higher correctness and time-efficiency,it is feasibility and practicality.
