Security Issues in Wireless Sensor Networks Definition Wireless Sensor Networks(WSNs) are wireless networks used to monitor physical and environmental conditions using devices called “sensors”.
Security Issues in Wireless Sensor Networks Motivating applications Seismic Structure Response Marine Micro-organisms Contaminant Transport Ecosystem complexity
Security Issues in Wireless Sensor Networks Along with the mentioned motivating applications, a wider spectrum of future applications include :- monitoring the highway traffic, pollution, wildfires, building security, water quality and even people’s heart rates. Protecting aggregated data that this system (WSNs) generates is very important considering the importance of the applications mentioned above.
Security Issues in Wireless Sensor Networks Security Techniques in WSNs (low level) Key establishment and trust setup Secrecy and Authentication Robustness to communication denial of service Secure Routing Reliance to node capture
Security Issues in Wireless Sensor Networks Discussion of a security technique Establishing pairwise keys for securing WSNs – Minimizing resource consumption of individual devices.
Security Issues in Wireless Sensor Networks Future Potential Research Redundancy in WSNs Securing wireless communication links against eavesdropping, tampering, traffic analysis etc. Finding ways to tolerate lack of physical security.
