Reconfiguration of RBAC schemes by genetic algorithms

Abstract

Nowadays,Role-Based Access Control (RBAC) is a widespread access control model. Search of the "users-roles" and "roles-permissions" mappings for the given “users-permissions” mapping is the problem of Data Mining called as Role Mining Problem (RMP). However,in the known works devoted to the RMP,the problem of RBAC scheme reconfiguration and methods for solving it are not considered. The paper defines the statement of the problem of RBAC scheme reconfiguration and suggests a genetic algorithm for solving it. Experimental results show the algorithm has a high enough effectiveness.
