Augmented reality (AR) is a virtual technology that integrates virtual information and objects into real environments, offering unprecedented possibilities in such fields such as architecture, education, and healthcare. Real-time communication and security protocols are critical to the successful deployment of AR applications to ensure user immersion, prevent motion sickness, and address security problems. This paper proposes a secure user-to-user (U2U) and user-to-infrastructure (U2I) authentication protocol suitable for edge computing-based AR environments. We also employ extended Chebyshev chaotic maps and physical unclonable functions to ensure security and efficiency during the authentication process. The proposed protocol initiates session keys after U2I authentication when an AR user enters the edge node area, facilitating secure U2U authentication for sharing data with nearby users. We conduct comprehensive studies of the security robustness of the proposed protocol using formal and informal analyses, including “Burrows–Abadi–Needham logic”, “Real-Or-Random model”, the “Scyther tool” and informal security analyses. Furthermore, we measure the performance of cryptographic primitives using the “Multiprecision Integer and Rational Arithmetic Cryptographic Library” Cryptographic SDK. We perform a comparative analysis of security features and functionality, and we conduct a computational and communication cost analysis. The results reveal that the proposed protocol can provide security and efficiency for edge computing-based AR environments, presenting the methods for seamless and secure real-time AR data exchanges for U2I and U2U communications.

Edge intelligence is a technology that integrates edge computing and artificial intelligence to achieve real-time and localized model generation. Thus, users can receive more precise and personalized services in vehicular ad hoc networks (VANETs) using edge intelligence. However, privacy and security challenges still exist, because sensitive data of the vehicle user is necessary for generating a high-accuracy AI model. In this paper, we propose an authentication scheme to preserve the privacy of user data in edge intelligence-enabled VANETs. The proposed scheme can establish a secure communication channel using fuzzy extractor, elliptic curve cryptography (ECC), and physical unclonable function (PUF) technology. The proposed data upload process can provide privacy of the data using local differential privacy and symmetric key encryption. We validate the security robustness of the proposed scheme using informal analysis, the Real-Or-Random (ROR) model, and the Scyther tool. Moreover, we evaluate the computation and communication efficiency of the proposed and related schemes using Multiprecision Integer and Rational Arithmetic Cryptographic Library (MIRACL) software development kit (SDK). We simulate the practical deployment of the proposed scheme using network simulator 3 (NS-3). Our results show that the proposed scheme has a performance improvement of 10∼48% compared to the state-of-the-art research. Thus, we can demonstrate that the proposed scheme provides comprehensive and secure communication for data management in edge intelligence-enabled VANET environments.
