Influence of Attribute Freshness on Decision Making in Usage Control

  title={Influence of Attribute Freshness on Decision Making in Usage Control},
  author={Leanid Krautsevich and Aliaksandr Lazouski and Fabio Martinelli and Artsiom Yautsiukhin},
The usage control (UCON) model demands for continuous control over objects of a system. Access decisions are done several times within a usage session and are performed on the basis of mutable attributes. Values of attributes in modern highly-dynamic and distributed systems sometimes are not up-to-date, because attributes may be updated by several entities and reside outside the system domain. Thus, the access decisions about a usage session are made under uncertainties, while existing usage… CONTINUE READING
