The next-generation Internet of vehicles (IoVs) seamlessly connects humans, vehicles, roadside units (RSUs), and service platforms, to improve road safety, enhance transit efficiency, and deliver comfort while conserving the environment. Currently, numerous entities communicate in the IoVs environment via insecure public channels that are susceptible to a variety of security assaults and threats. To address these security challenges, we design an anonymous authenticated key exchange mechanism for the IoVs in smart transportation supported by blockchain, referred to as AAKE-BIVT. AAKE-BIVT securely transmits traffic information to a cluster head, before heading to a nearby RSU utilizing the established secret session keys via mutual authentication and key agreement. A cloud server (CS) then securely aggregates data from related RSUs and generates transactions. The CS combines the transactions into blocks in a peer-to-peer network of CSs, and the blocks are confirmed and added to the blockchain via a voting-based consensus method. By means of rigorous informal security studies and formal security analysis through the random oracle model, we reveal that the proposed AAKE-BIVT is resistant to a broad range of potential security assaults in the IoVs environment. Furthermore, a comparative study reveals that AAKE-BIVT outperforms existing state-of-the-art techniques, in terms of security and functionality while being more efficient in terms of communication and computation. Additionally, the blockchain simulation validates the implementation viability of our proposed AAKE-BIVT.

In recent years, the mobile Internet of Things (MIoT) for online English education has quickly become an important means and main tool for people to learn and communicate English due it has characteristics and advantages such as high efficiency and no geographical restrictions. However, most MIoT for online English education is vulnerable to security attacks because of the online learning device's weak security protection measures and their communication channels with open wireless nature. To address these issues, herein, a novel secure authentication scheme in 6G‐enabled MIoT for online English education is proposed. The proposed authentication scheme does not rely on the ideal tamper‐proof device. In this scheme, the certificate and key are updated in real‐time to resist side‐channel attacks, and pseudonym seeds are used to generate pseudonyms to hide user's identity information and realise identity privacy protection. The scheme allows the attacker to continuously obtain private key information. Detailed security analysis proves that the authors’ scheme is unforgeable to adaptive selection message attacks and can satisfy the security requirements of 6G‐enabled MIoT for online English education. In addition, compared with other related studies, the proposed scheme achieves better performance in terms of computation and communication costs.

“…Despite its merits, the conventional centralized authentication models in VANETs suffer from a glaring vulnerability of potential communication bottleneck at the CA. With a high density of vehicles, a centralized authentication model in VANET with a single CA can get overloaded with authentication requests, which might lead to a single point of failure [7,6]. In the event of a CA failure, the entire VANET communication ecosystem can collapse, with the CA struggling to manage an overwhelming workload and consequential response delays [8].…”

Vehicular Ad-Hoc Networks (VANETs) offer enhanced road safety, efficient traffic management, and improved vehicle connectivity while dealing with privacy and security challenges in public communication. In these networks, authentication mechanisms are mandatory to establish trust among communicating entities, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), without losing identity and location-based privacy. The prevailing conventional authentication mechanisms frequently depend on a centralized trust authority (CA) to ensure the mutual verifiability of transmitted messages. Nevertheless, in scenarios where the density of vehicles within the network is notably high, an overwhelming influx of authentication requests may result in a communication bottleneck at the CA, leading to a single point of failure. This paper proposes a novel distributed authentication scheme in a decentralized VANET with multiple independent CAs connected to multiple local inspectors to eliminate a single point of failure. Furthermore, prior solutions lack the capability to immediately revoke a disputed vehicle that is transmitting malicious messages in the network. In this regard, the proposed scheme also facilitates an immediate revocation of a disputed sender to prevent other vehicles from further receiving malicious messages. As vehicles share time-sensitive data for driving assistance, our scheme minimizes the computation and communication costs for V2I key sharing and direct V2V authenticated message sharing significantly compared to previously proposed schemes. Using comparatively lightweight elliptic curve cryptography and eliminating the direct involvement of CAs in the authentication process, we have reduced the overall delays and achieved a maximum of ≈ 3.9 times faster V2I authenticated key sharing, and a maximum of ≈ 7.5 times faster V2V message sharing compared to state-of-the-art bilinear pairing-based protocols. A comprehensive efficiency analysis validates our scheme's ability to outperform time-sensitive responses, such as sending and receiving an alert within nearly 4 milliseconds.INDEX TERMS Vehicular Ad-Hoc Networks (VANETs); Single point of failure; Privacy-preserving authentication; Revocation, Security attacks on VANET; Elliptic Curve Digital Signatures (ECDSA).
