A Lightweight Cryptographic Algorithm with a Multi-Purpose Encipher Key for IoT

Internet of Things (IoT) is a rapidly developing technology that has the potential to change how individuals and businesses interact. However, the actual realization of IoT technology has been hampered by numerous security and privacy concerns. Increased number of CPU clock cycles among the traditional error sensitive cryptographic algorithms is an increasing concern in IoT devices. As most IoT devices rely on batteries for power, new low power consumption algorithms are required. As a result, we have created an algorithm that uses an encipher key for more than one security concern with the goal of reducing power consumption while maintaining security. Using a synthetic dataset, this study compared the proposed algorithm’s results against a synthetic algorithm. It results in less CPU time, fewer clock cycles, and higher throughput than the synthetic algorithm. Furthermore, during the encryption process, our algorithm was able to establish an encipher key that was later used to maintain message integrity. In this study, we have addressed the question of multi-purpose and power consumption.
