Abstract
The increasing adoption of smart vehicles and urban infrastructure necessitates efficient and secure parking management systems. This project proposes “An Anonymous Smart Parking and Payment Scheme in Vehicular Networks,” a solution designed to provide seamless, anonymous parking reservations and secure payments. Leveraging vehicular ad hoc networks (VANETs), blockchain technology, and cryptographic protocols, the scheme ensures user privacy while offering real-time parking slot availability and transaction transparency. This system enhances convenience for users and optimizes parking management for operators.
Introduction
Urbanization and the growing number of vehicles have led to challenges in parking management, including inefficiency, lack of security, and privacy concerns. Existing systems often expose sensitive user information during payment and reservation processes. This project addresses these issues by proposing a secure and anonymous smart parking system integrated into vehicular networks. The system uses real-time communication between vehicles and parking infrastructure, ensuring privacy-preserving transactions and reducing time spent searching for parking.
Existing System
Traditional parking and payment systems have several limitations:
- Manual Reservations: Require users to physically check for availability or use outdated systems for slot booking.
- Privacy Concerns: Personal and payment information is often stored in centralized systems, vulnerable to breaches.
- Inefficient Management: Lack of real-time updates on slot availability leads to overcrowding and frustration.
- Limited Scalability: Existing systems do not effectively integrate with modern vehicular networks or IoT devices.
Proposed System
The proposed scheme integrates vehicular networks, blockchain, and anonymous payment protocols to deliver a secure, user-friendly parking management solution. Key features include:
- Anonymous Parking Reservations: Users can book parking slots without revealing their identities through privacy-preserving cryptographic methods.
- Secure Payments: Transactions are processed using blockchain to ensure tamper-proof, secure payments.
- Real-Time Slot Updates: Vehicular networks provide real-time communication to relay parking slot availability.
- Scalable Design: Supports large-scale deployment across urban areas, integrating with IoT-enabled parking infrastructure.
Methodology
- System Architecture Design:
- VANET Integration: Vehicles communicate with Road-Side Units (RSUs) to exchange parking information.
- Blockchain Integration: Use a decentralized ledger to store parking reservations and payment details securely.
- Parking Slot Discovery:
- Real-time updates from IoT-enabled parking infrastructure relay availability to vehicles via VANETs.
- Vehicles request slot availability anonymously using cryptographic tokens.
- Anonymous Payment Protocol:
- Implement digital signatures and zero-knowledge proofs to ensure privacy during payment.
- Payments are processed securely via blockchain-based smart contracts.
- Reservation and Confirmation:
- Once a parking slot is selected, the system confirms the booking using encrypted communication.
- Users receive a digital token as proof of reservation, which is verified upon entry.
- Evaluation and Testing:
- Simulate the system using tools like SUMO (Simulation of Urban Mobility) for VANETs.
- Assess performance based on latency, throughput, privacy metrics, and scalability.
Technologies Used
- Programming Languages: Python, Solidity (for smart contracts).
- Blockchain Frameworks: Ethereum, Hyperledger.
- Vehicular Communication: VANET protocols (DSRC, 802.11p).
- Simulation Tools: NS-3, SUMO.
- Cryptographic Methods: Zero-Knowledge Proofs (ZKP), Digital Signatures, Homomorphic Encryption.
- IoT Integration: MQTT for communication between IoT-enabled parking infrastructure and vehicular networks.
Advantages
- Enhanced Privacy: Ensures user anonymity throughout the reservation and payment processes.
- Secure Transactions: Blockchain provides tamper-proof and transparent transaction management.
- Reduced Search Time: Real-time updates enable efficient slot discovery, reducing traffic congestion.
- Scalable and Robust: Designed to handle large-scale urban deployments.
Expected Outcomes
- Seamless, anonymous parking and payment experience for users.
- Optimized parking management for operators with real-time slot tracking.
- Reduced traffic congestion due to efficient slot discovery.
- A scalable, secure, and privacy-preserving solution for smart cities.
