摘　　要：电力云平台是电力业务的重要支撑平台之一。访问控制是电力云平台安全防护的一个重要方面。根据电力云平台的应用场景提出了一种基于信任度的属性访问控制模型(TM-ABAC)。该模型对访问请求中的各类属性进行信任度评价,决策模块依据评价结果动态调整访问控制策略,并引入访问控制历史记录和缓存技术以降低决策延迟。最后的仿真验证了该模型保护云平台资源的有效性和快速决策能力。Power cloud platform has become one of the important technical means to support power business.Access control is an essential aspect of the power cloud platform security.This paper designsatrustmeasurement-attribute based access control(TM-ABAC)model for the application scenario of the power cloud platform.The model evaluates the trust of each attribute in the access request,dynamically adjusts the authorization results according to the overall trust value,and introduces access control history and caching technology to reduce decision delay.The simulation results show that the model can effectively protect the resource security of the cloud platform and enable rapid and efficient decision-making.
