Cryptographic Techniques For Wireless Sensor Network Security - A Survey
The world is moving towards more promising application of wireless communication and electronics has
enabled the development of low-cost sensor networks. Wireless Sensor Networks (WSNs) has vast range of applications but
as the sensor network becomes more complex, security of these WSN becomes even more important. WSN faces major
security threats due to deployment of sensors in remote area and its geographical distributions. This has led the researchers
to explore solution in this emerging area. In this paper, key requirement for the WSN security are discussed. Various
cryptography techniques are studied such as symmetric key and public key which further contains Elliptic Curve
Cryptography (ECC), Pair based Cryptography (PBC) and Identity Based Cryptography (IBC).
