摘　　要：为有效提高同步数字层次(SDH)设备在电力通信系统中的安全性,提出一种基于贝叶斯网络的电力通信SDH设备安全评估模型。该模型从信息和物理相融合的角度分析SDH设备在以往电力通信中的潜在威胁和脆弱性,并依次建立了贝叶斯网络的安全评价模型,结合实际应用中的SDH设备分析各种防护方法对设备安全的影响。研究表明,该研究有利于决策者采取有效的防护措施,提升装备的安全性能。In order to effectively improve the security of Synchronous Digital Hierarchy(SDH)equipment in electric power communication system,this paper proposes a security evaluation model of SDH equipment for electric power communication based on Bayesian network.The model analyzes the potential threats and vulnerabilities of SDH equipment in the past power communication by analyzing them from the perspective of the convergence of information and physics,and establishes a security evaluation model of bayesian network in turn,and at the same time analyzes the impact of various protection methods on the security of the equipment in combination with the SDH equipment in practical applications.Research has shown that this study is beneficial for decision-makers to take effective protective measures and improve the safety performance of equipment.
