- Changyu Liu, Shoubin Dong, Huiling Li, Bin Lu, Alexander Hauptmann. 2014. A TPSAC Model and Its Application to Mechanical Cloud Simulation. Abstract: As a further development of the simulation grid, the cloud simulation platform is a new kind of network modeling as well as simulation platforms, and one of the hottest research directions in the cloud computing. While brings about the users with a lot of convenience, the cloud simulation shows also many severe security issues with its own characteristics, which can’t be solved effectively by the traditional access control strategies. According to the traditional role based access control(RBAC) model, this paper proposed a tree proxy-based and service-oriented access control(TPSAC) model. In the TPSAC model, a multilevel inherited meta permission and a multi-tree child-sibling linked list were adopted to separate the permission loading function and the permission distribution function to achieve a multi-granularity and quantized access control with the cloud simulation. A verification experiment on the CloudSim simulation platform was conducted then to demonstrate that the TPSAC model achieved the desired result.
