Study on Information Security of Distributed Sensor Networks Based on RBAC’s Resource Conflict

Wireless sensor networks will be widely deployed in the near future. While much research has focused on making these networks feasible and useful, security has received more attention. There exists a need for multilevel access control in these types of networks, in order to give authorization based on a node’s role – this is also called role-based access control (RBAC). SOD of RBAC is a good way to solve the problem of resource allocation and right management for improving the security of the system. According to the needs of the MVC-based information management system security, this paper first researches separation of duties (SOD) in Role-Based Access Control, as well as its application in practice, and then gives a program to implement RBAC model as the framework of SSH. Finally, this paper describes how to realize the RBAC in a specific information management system. Copyright © 2014 IFSA Publishing, S. L.
