Introduction
• VANETs support dynamic communication between fast-moving vehicles using
OBUs and RSUs. They facilitate safety-related applications and optimize
traffic through V2V and V2I protocols.
• VANETs demand robust security measures, including authentication for
communication between vehicles, privacy protection against unauthorized
access, and data verification to ensure integrity.
• Insider attacks in VANETs originate from authenticated entities within the
network.
• Balancing real-time communication and efficiency with comprehensive
security is crucial.
• Maintaining VANETs' efficiency while ensuring robust security against insider
threats requires a delicate balance in security measures to safeguard
communication while real-time exchanges between vehicles.

Abstract
• VANETs, while pivotal for traffic management and safety, face vulnerabilities
like insider attacks due to their open and dynamic nature, posing significant
challenges for privacy and authentication.
• A novel approach merges Proof of Chain (PoC) and Causal Dependency
mechanisms to address privacy concerns and resist insider attacks during
authentication in VANETs.
• Causal Dependency mechanisms ensure message sequencing, guarding against
replay attacks and aiding vehicles in determining the relevance of received
information to their current state.
• By implementing these methods, individual vehicle traceability is significantly
reduced, enabling data exchange, traffic management, and safety
communication without compromising privacy or security in VANETs.

• Implement causal dependency mechanisms to ensure proper message
sequencing, guarding against replay attacks and enabling accurate
relevance assessment of received information based on current conditions.
• Utilize causal dependency to reduce the traceability of individual cars
within the VANET network, enhancing privacy measures without
compromising communication efficiency.
• Implement causal dependency mechanisms to deter unauthorized tracking
or tracing of vehicles, thereby safeguarding sensitive location and identity
information.
• Utilize causal dependency to enable secure data exchange among vehicles
while reducing the risk of privacy breaches or malicious tracking attempts
in VANETs.

Motivation of the Work
• Address the vulnerability of VANETs to insider attacks and privacy
breaches by proposing a novel strategy combining Proof of Chain (PoC)
and Causal Dependency mechanisms.
• Aim to overcome challenges concerning privacy preservation and vehicle
traceability, which hinder the widespread deployment of VANETs, ensuring
that participating cars' identities and whereabouts remain protected.
• Enable secure communication among vehicles and roadside infrastructure
to manage traffic effectively while ensuring data integrity and non-
repudiation, crucial for conveying vital safety information.
• Strive to find a balance between robust security measures and the seamless
exchange of critical safety and traffic-related information, ensuring that
privacy and security concerns do not impede the functionality of VANETs.

13. 21-11-2023 Batch no : 13 13
Explanation
• OBUs generate a signature key that is used to sign their messages and prove
their identity.
• They apply a probabilistic function to their signature key.
• They introduce dummy packets contain random data instead of fake data.
• OBU’s send a request to join a Trusted Authority (TA).
• The TA receives the request from the OBU and verifies its signature key.
• If the verification is successful, the TA sends a certification key to the OBU.
• The certification key is used to prove the OBU’s identity and verify its
signature by other OBU’s or RSU’s.
• RSUs verify received messages using OBUs' certification-derived public
keys; upon successful signature validation, RSUs grant access to requested
services or information.

Methodology for the Proposed work
Causal Dependency
• Causal Dependency refers to the idea that in a VANET, the trustworthiness and
reliability of information exchanged between vehicles or between a vehicle
and roadside infrastructure should be established based on a causal
relationship.
Proof of Chain (PoC) Method
• Proof of Chain (PoC) is a security mechanism designed to establish the causal
dependency of messages or events in VANETs. It is a method used to provide
evidence that a particular event or message is part of a legitimate chain of events or
messages with a verifiable source.

17. 21-11-2023 Batch no : 13 17
Results and Discussion
• Causal dependency tracking captures the inter-node relationships and
dependencies, offering a more comprehensive view of data flow.
• Causal dependency enables the reconstruction of true data flow patterns,
enhancing the accuracy and reliability of tracing data propagation paths.
• Causal dependency is fundamental in preserving meaningful traceability as the
system matures and adapts to increasing complexities.
• Causal dependency fosters a robust framework that can navigate intricate
network scenarios and maintain reliable traceability in the evolving landscape
of blockchain technology.
