An Effective Hybrid Threefold Encrypted and Double Protected Cryptographic Technique in Wireless Sensor Networks

Wireless Sensor Network (WSN) is the most potential sector, and it is extensively applied in defense, medical, flood mitigation, and meteorology. Each component in a WSN is linked to the next component and shares data with it. Information protection is critical while transmitting data over a network. In the field of networks, privacy is critical. Premised on an assessment of current WSNs protection vulnerabilities, a blended cryptographic technique relied on WSNs is postulated, incorporating the features of symmetric and asymmetric cryptographic schemes. A hybrid cryptographic approach was proposed which was implemented by employing REA (Rijndael Encryption Approach) in the first stage, HFEA (Horst Feistel’s Encryption Approach) in the second stage, and improved- Rivest-Shamir-Adleman (i-RSA) in the last stage. The findings demonstrate that the technique may lower encryption and decryption time while maintaining safety. The results obtained from the suggested ensemble cryptographic technique in WSN are good in terms of execution time, power usage, communication cost, and storage cost.
