Abstract

In this article, we secure the healthcare data using low complexity hybrid cellular automata (CA) algorithm while enabling remote monitoring of patients using IoT (Internet of Things) network. Since IoT devices are limited to power and memory space, the traditional encryption and decryption algorithms, called as ciphers, cannot be executed owing to the inherent implementation complexities and power requirements. The results show that the encrypted data sequence passes the randomness tests as prescribed by the National Institute of Standards and Technology (NIST) and is suitable for cryptography. Comparison with the state-of-the-art methods proves the superiority of our proposed method in terms of run-time complexity. Using the proposed hybrid CA algorithm, we achieve an average execution time of 0.3892 seconds per kilobit (kb) of data.
