With the rapid technological advancement of the universal internet of vehicles (UIoV), it becomes crucial to ensure safe and secure communication over the network, in an effort to achieve the implementation objective of UIoV effectively. A UIoV is characterized by highly dynamic topology, scalability, and thus vulnerable to various types of security and privacy attacks (i.e., replay attack, impersonation attack, man-in-middle attack, non-repudiation, and modification). Since the components of UIoV are constrained by numerous factors (e.g., low memory devices, low power), which makes UIoV highly susceptible. Therefore, existing schemes to address the privacy and security facets of UIoV exhibit an enormous scope of improvement in terms of time complexity and efficiency. This paper presents a lightweight authentication and batch verification scheme (LABVS) for UIoV using a bilinear map and cryptographic operations (i.e., one-way hash function, concatenation, XOR) to minimize the rate of message loss occurred due to delay in response time as in single message verification scheme. Subsequently, the scheme results in a high level of security and privacy. Moreover, the performance analysis substantiates that LABVS minimizes the computational delay and has better performance in the delay-sensitive network in terms of security and privacy as compared to the existing schemes.

Ensuring secure transmission over the communication channel is a fundamental responsibility to achieve the implementation objective of universal internet of vehicles (UIoV) efficiently. Characteristics like highly dynamic topology and scalability of UIoV makes it more vulnerable to different types of privacy and security attacks. Considerable scope of improvement in terms of time complexity and performance can be observed within the existing schemes that address the privacy and security aspects of UIoV. In this paper, we present an improvised authentication and lightweight batch verification method for security and privacy in UIoV. The suggested method reduces the message loss rate, which occurred due to the response time delay by implementing some low-cost cryptographic operations like one-way hash function, concatenation, XOR, and bilinear map. Furthermore, the performance analysis proves that the proposed method is more reliable that reduces the computational delay and has a better performance in the delay-sensitive network as compared to the existing schemes. The experimental results are obtained by implementing the proposed scheme on a desktop-based configuration as well as Raspberry Pi 4.
