Lightweight Cryptography using Pairwise key generation and malicious node detection in large UAV

Abstract

Data security is very essential concern in network data transmission between various sensor nodes. Data encryption is the only way to provide security to sensitive information during the transmission. Various researchers have developed the different encryption techniques with heterogeneous encryption and decryption keys. Nevertheless, the standard does not include guidance for the administration, storage, or distribution of encryption keys. Various researchers proposed key management techniques, but those methods still generate high overhead during data communication. To eliminate such problems, we suggest lightweight key encryption using pairwise cryptography and malicious node detection from large UAVs. The proposed encryption algorithm compresses the cypher data, reducing the network overhead, and detecting malicious nodes provides higher security from internal and external intruders. In extensive experimental analysis, our simulation obtains better results than existing systems. That enhances around 7-9% throughput with other QoS parameters.
