LMFA-WSN: A Lightweight Multifactor Authentication Protocol for IoT-Based WSNs

Laxmi Chandolia, Chetan Kumar Verma, Pardeep Singh +2 more

The rapid proliferation of Internet of Things (IoT) devices in Wireless Sensor Networks (WSNs) has introduced a new dimension of connectivity, efficiency, and automation. However, it also presents significant security concerns, particularly in authentication. Strong and trustworthy authentication protocols are required to ensure secure communication and trustworthiness in IoT systems. For instance, Sahoo et al.’s authentication scheme has serious design flaws and lacks forward and backwards secrecy. Similarly, due to inherent design flaws, Mahmood et al.’s protocol is vulnerable to several major attacks. This paper presents a novel, lightweight authentication scheme for IoT-enabled WSNs to address these challenges. We prioritise low computational overhead, scalability, and strong security guarantees like perfect forward secrecy, backwards secrecy, and immunity against replay, MiTM, impersonation attacks, etc. We demonstrate through an extensive security analysis of the ROM model that our scheme addresses the shortcomings of existing methods. The protocol’s security is formally verified using the Scyther tool, and its practical feasibility is demonstrated through ESP32-based simulation on the wokwi platform, confirming correct cryptographic operations and session key management. This paper is a significant step toward designing an efficient and secure authentication system in line with the evolving requirements of modern IoT infrastructures.

Lightweight Certificateless Authenticated Key Agreement Protocol

Gervais Mwitende

Data security and privacy are important to prevent the reveal, modification and unauthorized usage of sensitive information. The introduction of using critical power devices for internet of things (IoTs), e-commerce, e-payment, and wireless sensor networks (WSNs) has brought a new challenge of security due to the low computation capability of sensors. Therefore, the lightweight authenticated key agreement protocols are important to protect their security and privacy. Several researches have been published about authenticated key agreement. However, there is a need of lightweight schemes that can fit with critical capability devices. Addition to that, a malicious key generation center (KGC) can become a threat to watch other users, i.e impersonate user by causing the key escrow problem. Therefore, we propose a lightweight certificateless Authenticated Key Agreement (AKA) based on the computation Diffie-Hellman problem (CDHP). The proposed protocol maintains the characteristics of certificateless public key cryptography. The protocol is split into two combined phases. In the first phase, our protocol establishes a session key between users (sender and receiver). In the second phase, we use a lightweight proxy blind signature based on elliptic curve discrete logarithm problem (ECDLP). The used proxy signature has small computation costs, and can fit for small devices such sensors and protects against un-authentication and un-authorization on decentralized system. Compared to the existing AKA schemes, our scheme has small computation costs. The protocol achieves the well known security features compared to the related protocols.
