【摘要】 数字通信系统作为舰船上重要的信息交换系统,为保证系统的安全与稳定通常会配以防御系统来抵御外来的恶意攻击。因此入侵防御的可靠性成为重要的衡量标准。传统的可靠性模型仅对防御效果进行评判,不对防御机制进行模型评判,导致评判为可靠的入侵防御系统或机制,仅具备单一种类的入侵防御功能,整体实用性不强。因此提出舰船数字通信系统中入侵防御可靠性模型构建研究,提出的可靠性模型构建中,首先引入了对入侵防御机制的分析计算,通过分析获得可靠性模型的全方位参量;然后通过获得的参量建立起可靠性模型,并对模型的可靠性数据做出详细分析;最后,通过数据导入、对比来证明提出设计可应用性与有效性。更多还原

【Abstract】 As an important information exchange system on ships, digital communication system is usually equipped with defense system to resist foreign malicious attacks in order to ensure the security and stability of the system. Therefore,the reliability of intrusion prevention has become an important measure. The traditional reliability model only evaluates the defense effect, does not judge the defense mechanism, which leads to the reliable intrusion prevention system or mechanism,which only has a single kind of intrusion prevention function, and the overall practicability is not strong. Therefore, this paper puts forward the research on the construction of intrusion prevention reliability model in ship digital communication system, and first introduces the analysis of intrusion prevention mechanism in the proposed reliability model construction. The omni-directional parameters of the reliability model are obtained by analysis; then the reliability model is established by the obtained parameters, and the reliability data of the model are analyzed in detail. Finally, through the data introduction, the design applicability and effectiveness are proved by comparison.更多还原
