AAA-based infrastructure for industrial wireless sensor networks

Over the past years, the deployment of sensor networks in industrial environments has attracted much attention in several business domains. An increasing number of applications have been developed, ranging from defence, public security, energy management, traffic control to health care. Integration of these sensor networks within domains relying on AAA (Authentication, Authorization and Accounting) infrastructures leads to the definition of novel services and profitable leveraging opportunities, while reinforcing the overall sensor networks security. This paper proposes architectures and solutions for wireless sensor networks in the field of sensor bootstrapping, (re-)authentication, secure routing and co-ownership. This work is carried out in the recently started “TWISNet: Trustworthy Wireless Industrial Sensor Networks” project1.
