LIGHT ACTKR: LIGHTWEIGHT ADVANCED ENCRYPTION CURVE CRYPTOGRAPHY AND ADAPTIVE TRUNCATED KARATSUBA RING-BASED SECURITY FRAMEWORK FOR POWER-CONSTRAINED SMART DEVICES

Abstract

In the current era, the world is increasingly connected to the internet, influencing high-level security as well as minimal complexity among power-constrained devices. Owing to the constrained nature of smart devices, existing security frameworks have faced certain challenges, including instability, lack of robustness, and inefficiency due to their complex structures. Consequently, the research proposes lightweight advanced encryption curve cryptography and an adaptive truncated Karatsuba ring-based (Light ACTKR) security framework to alleviate the aforementioned limitations among power-constrained smart devices. The proposed secure framework is composed of lightweight advanced encryption curve cryptography (LightAEnC)-based signature algorithm and Lightweight adaptive N-th degree truncated Karatsuba ring (Light ANTKR)-based data encryption algorithms to improve security within the power-constrained smart devices. Moreover, the research adopts a lightweight concept in both algorithms to reduce computational complexity within the power-constrained smart devices and ensure minimal storage capacity. In addition to that, the research introduced advanced secure parameters within the LightAEnC signature algorithm, which possibly enhance security and make it resilient to security threats. According to the merits of the Light ACTKR secure framework, gains 2s of encryption time, 2.060s of decryption time, and 352KB of memory usage at a number of 200 devices in comparison with the current results of the existing literature.
