An Efficient Lightweight Cryptographic Algorithm for IoT Security

To perform various tasks, different devices are interconnected and interact in several emerging areas. The emergence of the Internet of Things (IoT) and its applications makes it possible in the network for many constrained and low-resource devices to communicate, compute processes, and making a decision within themselves. But IoT has many challenges and problems, such as system power consumption, limited battery capacity, memory space, performance cost, resource constraints due to their small size and protection of the communication network. The traditional algorithms have been slow for data protection point of view, and cannot be used for data encryption on an IoT platform given the resource constraints. Therefore, this paper proposes lightweight cryptography based on the Tiny Encryption Algorithm (TEA) for an IoT driven setup to enhance speed benefit from software perspective rather than hardware implementation. The proposed algorithm was used to reduce the time for encryption in the IoT platform and to preserve the trade-off between security and efficiency. In terms of memory use, execution time, and precision, the proposed work is compared with recent works on lightweight start-ups. Results show that in an IoT driven setup, the algorithm is more secure and efficient, and more suitable for data securing.
