摘　　要：随着分布式系统的日益复杂，系统间的异构性、跨域访问、风险评估等越来越受到关注，传统的访问控制方式难以适应分布式环境下的发展。基于风险自适应访问控制（RAdAC）能够根据分布式整体环境和单系统的安全要求综合考虑访问者的访问风险，并根据访问者的访问要求以及一系列因素综合考虑访问授权。详细分析了传统访问控制下的缺陷。RAdAC的结构、执行流程以及在分布式环境下的应用，为该领域的进一步研究提供了思路。With the increasing complexity of distributed systems,more and more attention are concerned between systems,cross-domain access,risk assessment in systems.The traditional access control is difficult to adapt to the development of a distributed environment.Risk-Adaptable Access Control（RAdAC）can consider the risk of the visitor＇s access according to the overall environment of distributed ＇and single-system security requirements,and in accordance with the access requirements of visitors and a series of factors to consider access authorization.The paper detailed analysis of the shortcomings of traditional access control,RAdAC structure,implementation processes,applications in distributed environment,and provided research ideas in this field.
