Role-Evolution in Role-based Access Control System

Abstract

Security is a major concern in today’s digital world. Role based access control provides a mechanism for protecting the digital information in an organization by assigning roles to the individual user and giving permissions to the assigned roles for accessing any resources. This paper describes the importance of roles in an organization and the evolutionary changes that occurs with respect to the organizational roles. Here the role is defined as an entity and the attributes of the roles have been identified with their related operations. The evolutionary changes that happens to the roles in an organization is identified and evolutionary algorithms have been proposed to handle these changes which helps in simplifying the formulation of access control policies.
