Cryptography Encryption of Security in Wireless Sensor Network

For past two decade, Wireless Sensor Networks (WSNs) have emerged with the result of the low-cost availability, undersized range, and easy-to-install sensors. WSN technologies transmit real-time sensor data from specified monitoring environment in a backend to process as well as analysis. Because of the ubiquity of wireless communication channels, security and management problems have emerged as hot concepts in WSN systems. This research proposed an Improved Elliptic Key Cryptography (IEKC) based security method. Data encryption as well as decryption is achieved through IKEC. The fundamental method feature is about the source code of node's contain private keys that secure various keys in non-volatile memory. The Chicken Swarm Optimization (CSO) algorithm has highly efficient in intelligence optimization system that performs well when handling global optimization Positions (GOPs). The CSO algorithm has executes badly in complexness GOPs due to various errors, causing the iteration to rapidly descend into a local minimum. The provided approach protects against replay, Sybil attacks and DoS. Cluster chiefs have been selected by Improved CSO (ICSO), and nodes are ordered based on network sizes. Based on the simulating results, this mechanism of security efficiently opposes various attacks with lesser assets and considerably improves the network's resilience for capturing node. Experiment result indicates the suggested paradigm is efficient in terms of packet delivery Ratio (PDR), and throughput
