A Survey on Secure Mechanism for Wireless Sensor Networks

As Wireless Sensor Networks are proceeding towards wide-spread deployment, security issues become a central issue. Assuring the security of communication and access control in Wireless Sensor Networks (WSNs) has huge importance. So far, huge research has focused on making Wireless Sensor Networks feasible and useful, and has not concentrated on security. A security technique, MoteSec-Aware, is presented based on the network layer for WSNs with concentrate on secure network protocol and data access control. For identifying the replay and jamming attacks focused around the symmetric key cryptography utilizing AES as a part of OCB mode, a Virtual Counter Manager (VCM) with a synchronized incremental counter is introduced in the secure network protocol of MoteSec-Aware. The Key-Lock Matching (KLM) system to stop unauthorized access is investigated for access control. MoteSec-Aware is built for the TelosB model sensor platform running TinyOS 1.1.15, and conduct field tests and TOSSIM-based simulations to assess the performance of MoteSec-Aware. The results show that MoteSec-Aware expends substantially less energy, yet accomplishes higher security levels than a number of state-of-the-art techniques.
