A Data Integrity Framework for IoT Leveraging the Blowfish Encryption Algorithm

The Internet of Things (IoT) is anticipated to create several new opportunities for enterprises to provide innovative services. When it comes to the Internet of Things, confidentiality protects the privacy of IoT devices while integrity looks after the data stored on the device. Data integrity is a process that makes sure data is accurate, complete, and consistent over the data’s lifecycle. This paper discusses how to ensure data integrity in IoT applications. While information flow analysis or cryptography might be used to evaluate secrecy, integrity is still a difficult problem to solve. This paper proposes to guarantee data integrity using blow fish algorithm. To examine the performance effectiveness, encryption time, decryption time, Packet Transmission Success Rate and end to end delay are evaluated.
