Abstract:	The significant development of the Internet of Things (IoT) has allowed businesses and consumers to utilize various resource-constrained devices, including smartphones, connected vehicles, intelligent systems, and services. However, security, interoperability, power/processing capabilities, and availability are the primary challenges of resource-constrained devices that can affect the implementation of an IoT system. This paper proposes an efficient, Lightweight Authenticated Encryption Protocol (LAEP) that uses a one-dimensional (1-D) logistic Chaotic map for secret key generation and a key-dependent Sbox for generating confidential and authenticated data. A two-point Diffie-Hellman key exchange algorithm and one-way hash function facilitated the secret key sharing. Furthermore, a novel method of key-dependent S-box is imposed on the existing PRESENT algorithm, which addresses security and authenticity. It achieves 50% of the Strict Avalanche Criterion (SAC) and 85% of non-linearity with 1730 Gate Equivalents (GEs). The computational analysis proved that the proposed scheme consumes less power and one-fourth of computation time, which is better than the other encryption scheme. Furthermore, the results of the AVISPA simulation demonstrate that the LAEP effectively resists the attacks. Additionally, a real-world testbed environment was implemented using the Raspberry Pi 4 Model B, and the experimental findings confirm the robustness of the proposed protocol. As a result, the proposed protocol is ideal for resource-constrained devices. [ABSTRACT FROM AUTHOR]
