Secure Robotaxi-Based eAuction Protocol From Proxy Pixel++ Re-Signature Scheme

Robotaxis under the category of Autonomous vehicles (AVs) transform urban transportation through enhanced safety and efficiency. The eAuction systems used to allocate autonomous vehicles encounter significant privacy, security and anonymity risks that impact both customers and service providers. The provision of secure robotaxi services requires appropriate solutions to these problems. We introduce a Robotaxi-based eAuction Protocol from Proxy Pixel++ Re-Signature Scheme to guarantee bid anonymity and unlinkability. The protocol protects customer privacy while maintaining data integrity through a transparent bidding process and competitive pricing mechanisms as well as dispute resolution and revocation features. The adaptive chosen message attack (CMA) model demonstrates the unforgeability of both original signatures and re-signatures. The protocol undergoes extensive simulation testing to prove its substantial benefits against competing protocols. The proposed system demonstrates both reduced computational overhead and satisfaction of essential security requirements which makes it highly appropriate for real-world autonomous transportation systems.
