The high-performance policy assessment remarkably supports RBAC as compared to the Trust Management Systems. The mapping of the Trust Management Scheme to RBAC can be non-trivial as mentioned by the Li and Tripunitara. The reduction in the evaluation time related to the access control queries can be achieved via utilization of caching mechanism and by implementing the policy evaluation framework. Although, the caching advanced only valid if the cache is convinced to return to the central PDP. Furthermore, the cache techniques guarantee proper reliable cache. The concept of access control risks defines the fuzziness of distinction via restricting an access and as a replacement; every access is in relation to the potential impairment and utility. The concept is re utilized for evaluating the potential impact for every access.

In disseminated system every node constructs its own cache in association with the other nodes in order to achieve precise cache. Moreover, the cache methodology revisit to a confined decision on a request (Hunter, 2005). The method proposed by the Bell-LaPadula that allows estimating former decisions that are based on the request and responses presented previously (Hunter, 2005).

The interference techniques demands knowledge associated with the access control model, as they are most effective and intelligent for hierarchical access models and structured access models (Hunter, 2005). Likewise, the proposed solution incorporates the relationship of objects and subjects in a typical database. However, there is still a requirement for learning the subject and object space. The utilization of machines for making decisions pertaining to access control is also presented, in which the researchers of the proposed solution make note of the behavior of a classifier that reverts a decision after making a conflict at the centralized PDP (Hunter, 2005).
