Sensor and Data Privacy in Industrial Wireless Sensor Networks

Over the past years, the deployment of wireless sensor networks (WSNs) into industrial environments attracted a lot of business domains (e.g., defence, public security, energy management and traffic control, and health care). Sensor networks are particularly interesting due to their ability to control and monitor physical environments. Nevertheless, several security challenges deter that integration. In particular, privacy protection is a challenging problem, due to the sensor resources' constrain and the self-organizing nature of WSN architecture. This paper analyses the existing approaches for privacy protection in WSNs and investigates the approaches that aim at supporting the integration of privacy-preserving WSNs into large scale industrial environments. This work is carried out in the recently started EU funded project "TWISNet: Trustworthy Wireless Industrial Sensor Networks".
