【Abstract】Private parking spot sharing can help relieve the parking problem due to insufficient public parking facilities in big cities. Meanwhile, users who share parking spots can also benefit, either by getting a free parking spot or by obtaining a parking fee payment. However, when users are sharing their private parking spots, their privacy is inevitable to be disclosed. This could put these parking spots owners into some unnecessary inconveniences, such as identity theft. Existing private parking spot sharing schemes either do not consider privacy issues. Or, when privacy is taken into account, they assume the existence of a trusted third party. To address these issues, we propose a privacy-enhanced private parking spot sharing scheme without trusted third parties. Specifically, we use market design method to share parking spots. We achieve enhanced privacy with decentralized anonymous credentials and confidential anonymous payment with a variant Monero. Extensive analysis confirms the security and privacy protection of the proposed scheme. Performance evaluation shows that the proposed scheme has moderate computational costs and communication overhead.
