Establishing Symmetric Pairwise-Keys Using Public-Key Cryptography In Wireless Sensor Networks (Wsn)

Wireless Sensor Networks (WSN) are becoming an increasingly popular technology for data collection. Since data is of significant importance in the current era, security of the data is essentially indispensable. Because the nodes deployed are usually on an unattended environment, security of the data communicated between the wireless sensor nodes is of utmost importance. A secure established connection between two nodes in a WSN promises a number of preventive measures against different threats but the main issue is to establish the secure connection between any two nodes in a wireless sensor network. With limited resources on a wireless sensor node in mind, this research focuses on establishing Symmetric-Pairwise keys between any two WSN nodes using Public-Key Cryptography (pkc) - which in this case is Elliptic Curve Cryptography.
