摘　　要：多自治域互操作中的风险评估是异构环境下信息安全的重要内容。本文在分析风险特征的基础上给出了基于模糊评判的多自治域互操作风险事件关联算法;同时引入确信度学习方法来为保证精确性,有效检测和识别重复风险事件发生,提取风险事件类别;最后引入互操作服务风险指数概念,实时评估多自治域互操作服务的安全态势和风险状况。Risk assessment in the system for the interoperation in multi-autonomous domains is the Key matter oi trdor- mation security management. A risk correlation method is given in this paper based on analysing the risk correlation charac- teristics. This method correlates with many kinds of risk factors, and the confidence learning method with monitoring is also introduced for high correlation accuracy. By means of these skills above, it can effectively detect and identify the same risk e- vents,and capture all kinds of risk events. The concept of risk exponent is also introduced during the interoperation in multi- autonomous domains.
