Improved Diffie-Hellman Key Exchange Using Elliptic Curve (IDHECC) Scheme for Securing Wireless Sensor Networks Routing Data

In Wireless Sensor Network (WSN) is a large scale network with thousands of tiny sensors moreover is of utmost importance as it is used in real time applications. Currently WSN is required for up-to-the-minute applications which include Internet of Things, Smart Card, Smart Grid, Smart Phone and Smart City. However the greatest issue in sensor network is secure communication for which key management is the primary objective. Existing key management techniques have many limitations such as prior deployment knowledge, transmission range, insecure communication and node captured by the adversary. The proposed novel ECC and diffie-hellman key exchange algorithm provides better transmission range and secure communication. The overall network is separated into circular tracks and triangular sectors. Energy conservation Routing Protocol was used for routing of data in WSN, which reduces the delay with increased packet delivery ratio. Further for secure routing Improved Diffie-Hellman key exchange using Elliptic Curve (IDHECC), which reduces the memory space and computational overhead than the existing Elliptic Curve Cryptography (ECC) key management scheme for Securing WSN (Wireless sensor Network).
