Enhancing highly-collaborative access control system using a new role-mapping algorithm

The collaboration among different organizations is considered one of the main benefits moving applications and services to a cloud computing environment. Unfortunately, this raises many challenges such as access sensitive resources by unauthorized people. Usually, role based access-control (RBAC) Model deployed in large organizations. work paper mainly considering authorization scalability problem, which comes out due increase shared and/or number collaborating same Therefore, proposes replacing cross-domain RBAC rules with role-to-role (RTR) mapping all RTR are generated using newly proposed role-mapping algorithm. A comparative study has been performed evaluate performance algorithm concerning rule-store size response time. According results, it found that achieves more saving stored minimizes reduces Additionally, model implemented applying concurrent approach achieve would be suitable highly-collaborative environments
