Nevertheless its computation is very complex and the existing algorithms are restricted to use limited amount of data.
Due to the openness and extensibility of the cloud computing environment, the requirement of authorization management in UCON model become more and more complex, and the existing UCON model is no longer applicable in cloud computing environment.
