Advancements in the technologies of micro electromechanical and embedded chips make it possible to design a tiny device with more powerful computations and communication features such as cryptography and wireless communication with low energy consumptions. Sensor devices are tiny in size and have limited resource (memory, energy, processing, low transmission range) such as MICA2DOT and T-Mote Sky. Traditional public key cryptographic techniques are not possible on these devices (such as RSA). To handle this problem ECC techniques have been developed for these small and limited resource devices. ECC consumes less energy and requires less memory and bandwidth than RSA with same level of security. Public key cryptographic techniques provide more security as compare to symmetric key cryptographic techniques at the cost of more energy consumption and more resource utilization. So, for balancing energy consumption and security level the Hybrid cryptographic techniques have been developed for Wireless Sensor Networks (WSNs). By using Hybrid cryptographic techniques few security frameworks have been proposed in past few years to provide more security and with less memory requirements. This paper provides an overview of some common WSNs concepts and proposed a security framework for LEACH protocols.
