摘要
针对以耦合率为指标之一的C4ISR系统体系结构设计合理性验证评估问题,从功能系统间交互信息的安全性需求出发,通过推理揭示出密钥关系的耦合本质,进而提出并分析了密钥关联耦合的概念及其属性。给出了密钥关联耦合的定量度量方法,采用该方法能在体系结构设计结束后就实施并完成度量,且不必考虑密码算法及密钥长度等细节问题。利用Briand等人提出的准则证明了度量方法的科学性与合理性,并结合案例说明了度量方法的可行性与易操作性。
Aiming at the subject of using indexes including the coupling rate to validate and evaluate the design rationality of C^4ISRsystem architecture, started with the security requirements ot interactive information between subsystems, the concept of key associationcoupling is proposed and its attributes after uncovered the coupling essence of key relationship are analyzed by reasoning. A quantitative measurement method is given. This method has no business with the details such as the cryptography algorithm or the length of the key, and it is used to get the value of the key association coupling as song as the architecture is designed. This method is proved scientific and rational according to the rules proposed by Briand and his partners, and its feasibility and easiness during operation are also reflected through an example.
