IoT-ID3PAKA: Efficient and Robust ID-3PAKA Protocol for Resource-Constrained IoT Devices

摘要

The Internet of Things (IoT) is an emerging technology that has become popular in many applications, such as transportation, agriculture, healthcare, industrial automation, robotics, etc. IoT devices are interconnected via the Internet, and secure message communication between them is a challenging task. An authenticated key agreement (AKA) protocol can solve such an issue. This article designed and implemented an identity-based three-party AKA (IoT-ID3PAKA) protocol to establish a shared session key among three IoT devices. The current state-of-the-art identity-based 3PAKA (ID-3PAKA) protocols are unsuitable for resource-constrained IoT devices because almost all of them undergo various security attacks and require higher execution and communication overheads. The provable security of the proposed IoT-ID3PAKA protocol relies on the hardness assumption of the elliptic curve-based computational Diffie–Hellman problem. The execution time of IoT-ID3PAKA for the security levels: 80, 112, 128, 192, and 256 bits on a Raspberry Pi 4 device is estimated and compared with the existing ID-3PAKA protocols.
