+This project includes providing a secure platform that is transparent for applications in wireless sensor networks (WSN) - WSNProtectLayer. Our platform includes intrusion detection system (IDS) detecting active attacks. We consider privacy issues to prevent passive attacks on the WSN. We also propose secrecy amplification protocols and evaluate key management schemes. Current work includes parametrised attacker simulated on KMSforWSN framework.

+Additionally, we are developing an optimization framework for the IDS incorporating MiXiM simulator. Evolutionary algorithms are used to optimize the IDS's performance.
