Abstract: Narrowband Internet of Things (NB-IoT) is a wireless communication technology that enables a wide range of applications, from smart cities to industrial automation. As a part of the 5G extension, NB-IoT promises to connect billions of devices with low-power and low-cost requirements. However, with the advent of quantum computers, the incoming NB-IoT era is already under threat by these devices, which might break the conventional cryptographic algorithms that can be adapted to secure NB-IoT devices on large scale. In this context, we investigate the feasibility of using post-quantum key exchange and signature algorithms for securing NB-IoT applications. We develop a realistic ns-3 environment to represent the characteristics of NB-IoT networks and analyze the usage of post-quantum algorithms to secure communication. Our findings suggest that using NIST-selected post-quantum key-exchange protocol Kyber does not introduce significant overhead, but post-quantum signature schemes can result in impractical latency times and lower throughputs.

Abstract: The use of Electric Vehicles (EVs) has been gaining traction in recent years due to various reasons. While charging their EVs, users expose their identity and personal details, and an adversary being able to identify and track where users charge their EVs is a potential privacy threat. In this article, we propose a user-empowered privacy-preserving authentication protocol for EV charging based on Decentralized Identifier (DID) and Verifiable Credential (VC) to provide Zero-Knowledge Proof (ZKP)-security. The proposed method gives users full control over their identities and allows them to remain anonymous while charging from any station. Giving control over their identities empowers users. At the same time, by making use of the concept of VC, other parties can verify that a user is legitimate and authenticate the user before providing charging services. Hence, the proposed protocol makes the charging service available in a secure way, while empowering users and preserving their privacy. Collapse
