摘要
以信任度评价指标的可用性、可靠性、完整性、安全防护性、可维护性、以及机密性等6个因素为出发点,建立信任评价指标体系.在此基础上,考虑到信任的主观性及主体对客体评价、判断所具有的模糊性,选用模糊综合评价方法,建立一种与数字系统信任管理相关的,可用于多个实体信任度评估的数学模型.对3个样本实体的信任状况进行实证研究,结果可为数字系统的信任管理提供依据.
Taking six factors, such as availability, reliability, integrity, safety, maintainability and confidentiality as the starting point of trust evaluation index, a trust assessment index system is built up. Base on this and considering the subjectivity of trust and fuzziness of opinion and estimation for subject to object, a fuzzy synthetic evaluation method is selected and a mathematical model associated trust management of digital system and used in more entities is established. The process of evaluation using the model is demonstrated for three examples. The result of evaluation can provide gist for trust management of digital systems.
