“…However, when deciphering messages, nodes only need to store and utilize their own private keys, meaning that the cardinality of received messages is always one. Several solutions created for securing VANETs rely on using traditional asymmetric cryptography, such as [7] [8] [10].…”

VANET security is an evolving topic in mobile networks, as providing a secure layer of communications in such a dynamic and fast network is a challenge. The work presented in this article was conducted in order to verify and evaluate the feasibility of applying group broadcast cryptography to the VANET environment, as an attempt to gain performance by decreasing the number of messages in the wireless network. Group broadcast is a symmetric/asymmetric hybrid cryptography method, aiming to merge the best of the two approaches without their major drawbacks. Simulations were setup and run using the ONE simulator, comparing the usage of the three different cryptography approaches for VANETs. Results consider the number of connections, the number messages and the number of revocation messages per day. The resulting data promises that group broadcast encryption can be used to simplify the encrypting phase, reduce required storage and significantly decrease the number of messages in the network.

“…Therefore, security solutions should be adapted to meet the specific communication constraints of VANETs while maintaining low latency. Multiple attack routes that potentially compromise the safety of VANETs have been uncovered using secondary sources [6] . These include manipulating messages, eavesdropping conversations, assuming another person's identity, and inserting malicious messages.…”

In wireless ad hoc networks, security is a critical concern due to their dynamic and distributed nature. One of the most challenging security threats in these networks is the black hole attack, where malicious nodes drop packets rather than forwarding them, leading to disruption in communication. To mitigate such attacks, various routing techniques have been proposed, including proactive and reactive approaches. This paper aims to provide a comprehensive analysis of proactive and reactive routing techniques in simulating black hole assaults. We delve into the characteristics, advantages, and limitations of each approach, providing insights into their effectiveness in combating black hole attacks. In addition, it uses Roadside Units (RSUs) to communicate data and promote network-wide use. The performance of PAODV_RTPSN is evaluated thoroughly with the use of several important metrics, including the Packet Drop Rate (PDR), Average End-to-End Delay (E2ED), Jitter, Network Throughput (Th), and Network Routing Load (NRL). The study involves simulations with 500 nodes over 1000 seconds in NS2, comparing AODV, AODV under black hole attacks, and the proposed hybrid approach. The results demonstrate that PAODV_RTPSN significantly mitigates the adverse effects of black hole attacks, improving PDR, Th, E2ED, Jitter, and NRL. In conclusion, this research contributes a robust solution to the security challenge of black hole attacks in VANETs while upholding user anonymity. PAODV_RTPSN substantially improves network performance, making VANETs more resilient and trustworthy for drivers and authorities.
