Shared vehicles provided by car-sharing systems can help address several issues in cities, such as reducing the use of personal cars. The popularity of the Internet of Things has made it easier for people to access shared cars through simple mobile operations. However, the car-sharing system has vulnerabilities in terms of security, such as sensitive user data transmitted through public channels, which could be accessed by attackers for illegal purposes. Therefore, it\'s crucial to establish a secure authentication protocol. In addition, the traditional centralized car-sharing system has a single point of failure, necessitating a decentralized car-sharing scheme, which was proposed in this study using blockchain technology. This model ensures data integrity and offers a decentralized vehicle-sharing service with anonymous authentication of participating entities. The proposed car-sharing system provides mutual authentication, protects against several attacks, and was analyzed for computation and communication costs. The proposed blockchain-based decentralized car-sharing scheme has several advantages over the traditional centralized model. For example, it eliminates the need for a trusted third party. the proposed blockchain-based decentralized car-sharing scheme offers a more secure and efficient approach to car-sharing, addressing several security issues associated with traditional centralized models. It ensures data integrity and provides mutual authentication while offering anonymity to participating entities, making it a promising solution for car-sharing systems in smart cities. to maintain the integrity of the system, as blockchain technology is based on a distributed ledger that allows participants to validate transactions. Additionally, the anonymity of the participating entities ensures privacy while providing security against unauthorized access to sensitive data. Moreover, the proposed scheme\'s security was analyzed using several methods, such as informal analysis, AVISPA simulation, and BAN logic evaluation, to ensure the system\'s resilience to various attacks.
Vehicle sharing was introduced a long time ago but it has gained attention and popularity in recent times or maybe in the past few decades.To address transportation problems in urban areas such as traffic congestion, pollution from combustion engines, and limited parking due to the increase in cars, car-sharing systems have been introduced. These systems allow users to access a fleet of shared vehicles without the cost and responsibility of ownership, reducing private car ownership.
The car-sharing market has grown significantly and is expected to continue to expand.
However, the traditional car-sharing system suffers from security issues, particularly in a centralized structure where user information and service records are stored.
A centralized server can be vulnerable to attacks from malicious attackers, leading to data loss, tampering, and privacy breaches.
To overcome these problems, two types of car-sharing service models have emerged: business-to-customer (B2C) and peer- to-peer (P2P). B2C companies offer shared cars that can be rented by users, while P2P models allow car owners to rent out their private vehicles to other users on a short-term basis. In both models, a service provider acts as an intermediary, providing an online platform and customer support to make the exchange possible.
Users can book and rent a shared car through an online service platform using their smartphones. However, because the information is transmitted in a public channel, it is vulnerable to eavesdropping, forgery, deletion, and modification by malicious attackers. Therefore, secure authentication is essential to provide a secure communication channel, and user authentication is necessary to verify that the user has the right and ability to drive a vehicle.
To overcome the security issues inherent in centralized structures, it is essential to decentralize the system and distribute the information among users in a peer-to-peer network. In this system, available cars are spread throughout the city in reserved parking spots, making it easy for users to find them and book their ride.
A. Problem Statement
In a conventional car-sharing system, the centralized service server stores and manages the user's information and service details. However, this structure has a vulnerability to single- point failures by malicious attackers. If the service server is hacked and all sharing records are erased, users will lose access to the previously utilized car information if there is a missing item on the car. Moreover, if sharing records are altered or edited when users conduct fraudulent activities during car- sharing, obtaining user evidence becomes difficult. Additionally, if the saved data is leaked, it poses severe privacy concerns since it relates to user privacy. Therefore, addressing the issues caused by a centralized structure is crucial.
To develop a Decentralize vehicle-sharing system which includes:
II. LITERATURE SURVEY
In modern world, ride or vehicle sharing is becoming a popular and effective of reducing the traffic and make the transportation effective and reliable. The rise of digital technologies and cryptocurrencies over the beyond decade has brought big modifications in lots of enterprise sectors. The proposed decentralized ridesharing system is built on the Ethereum blockchain network. With most of the contemporary ridesharing methods being controlled via crucial authorities and huge groups, there is a need for a decentralized device in public area to ensure that ridesharing device will become smoother. this paper are to  shows how can vehicle sharing system can reduce the traffic to an extent in any city and potentially decrease the number of cars up to 32% and it can be more in some of the developed cities and one of the important aspects is the effective matching of riders to share rides and finding drivers for those riders and make it reliable and cost effective
 it shows a matching algorithm for the dynamic vehicle sharing based on the network partitioning which is presented in this article or the paper. The main aim of this approach is to minimize the number of kilometers or the mileage driven by the service provider while keeping the account of inconvenience caused by picking the passengers from their current place and dropping them to their desired location and this current problem should be addressed in a given scale requires the space in which the algorithm searchers and matches. This is achieved by partitioning the road network into district regions which represent certain sub- structures of the road network.  in automated or the In a dynamic ride-sharing system, the drivers or riders may not always agree to the matches suggested by the ride-share provider. This makes it essential to consider the reliability and stability of the matches being made and the service provided by the provider. By adopting this approach, various methods can be employed to generate stable or nearly stable ride-sharing solutions for customers.
Failure to consider stability when making matches may result in relatively unstable solutions to the problem. However, we have demonstrated that enforcing complete stability requires only a small price in terms of reduced system vehicle mileage savings. This can result in more sustainable ride-share systems in the long run.  a new way of decentralized solution for vehicle communication. It incorporates three primary layers to explore the possibility of using blockchain for communication in the IOV. A prototype of the smart contract on the testnet of Ethereum have been deployed. The proposed solution considers several properties of the solution, including the integrity, availability and the security to test whether the Blockchain is an efficient and secure mechanism for IoV communications. The results showed that this decentralized system can be considered as the real time solution and application for the main challenges of vehicle to X communications such as centralization, security and the lack of privacy.  have developed Traffic-Chain and a secure and privacy preserved decentralized traffic information collection service or the system. And, we have implemented a two layer blockchain architecture for efficient communication and block updating in TrafficChain. Besides, a privacy-preserving scheme has been devised to protect users’ identities and driving routes. Moreover, we have considered two critical kinds of attacks, i.e., Byzantine and Sybil attacks, in TrafficChain, and developed deep learning based schemes to defend against them. a car sharing domain within a blockchain-based ecosystem incorporating governmental authorities such as a transport authority Kraftfahrt-Bundesamt/KBA and automobile industry partners was chosen. In order to enforce the privacy requirements, the cryptographic techniques based on anonymous credentials and zero-knowledge proofs were used. The proof-of-concepts are implemented leveraging two technologies, namely Ethereum with ZoKrates and Hyperledger Indy. The first solution based on ZoKrates uses zkSnarks for zero-knowledge proof generation and Ethereum blockchain for proof verification.  we proposed a decentralized ride sharing organization scheme based on the revolutionary public blockchain. The scheme is decentralized since all interactions made by drivers/riders are done through the blockchain, and the system does not need any of organization or any centralized company to operate or to manage it. Moreover, there is no need to reveal any private information such a email address, phone number or credit card number. Using cloaked technique, only selected driver/rider know the exact pick-up location without revealing any sensitive information to the public.  presents a novel or an article on privacy preserving identity verification system, with the extending zero knowledge proof on top of blockchain for use in vehicle sharing applications. In this proposed scheme or system enables the secure verification without the This paragraph discusses a prototype system that addresses the issue of exchanging sensitive information between unauthorized parties.
However, the so? called demand?offer asymmetric problem that is the unbalanced offer and demand of vehicles typically experienced in one-new way sharing systems severely affects their economic viability as it implies that considerable human and financial resources will be engaged in relocating vehicles to satisfy customer demand.  A reactive optimal method and scalable real-time performance has been introduced for assigning customer requests to a fleet of vehicles of changing capacity, which quantifies experimentally the tradeoff between fleet size, capacity, waiting time, travel time, and operational charges for low- and medium-capacity vehicles such as taxis in a large-scale city dataset. Assuming one person per ride, it has been shown that only 4,000 taxis of capacity four could serve 98% of the taxi rides presently served by over 11,000 taxis. For ride-sharing, a vehicle capacity of two is sufficient when a small trip delay of 2 min is imposed. Higher-capacity vehicles are found to increase the service rate, reduce the delay time, and reduce the distance traveled by every vehicle if a maximum delay of 5 min or more is allowed, which is comparable to the time spent retrieving a car from parking. Analysis shows that the parameters of a car-pooling service such as vehicle capacity and size depend on the quality of services requirements and demand, and that it can provide a substantial improvement in city transportation systems.  Their main objective was to develop a decentralized application for peer-to-peer car sharing. They addressed issues that centralized car-sharing services encountered, such as denial of service and data tampering, by using blockchain technology that is decentralized and immutable. Their approach enhances the security of the entire system by employing blockchain and two different types of security systems. For example, blockchain technology makes it challenging for a hacker to hijack a car since they would only have a digital key to control the vehicle's systems. The digital key is distributed across the internet and can only be accessed with the owner's permission, making it more difficult to hack compared to a single server. Tokenizing car keys can cover many use cases related to car-sharing services, including preventing partial deadlock of cars. Their decentralized application currently includes major activities such as creating the car token, issuing a major unlock token, and offering tokenized renting solutions. Tests indicate that making a car available for rental is a simple process. Additionally, users can rent a car in an average of 12.146 seconds, providing a user experience that is comparable to using centralized car-sharing services.  Their proposal is for an authentication scheme based on a semi-trusted authority in VANETs was found to be effective. The system involves combining a self-healing key distribution method with a certificateless signature in a semi- trusted authority framework, which eliminates the need for receivers to request CRLs. As a result, vehicles do not have to store CRLs, saving storage space and communication resources. Additionally, this approach reduces computational costs and improves message authentication efficiency. Since the proposed scheme is based on a semi-trusted authority, it is a superior approach.  it is motivated by the enhanced interest in shared mobility, this research work checks how blockchain and IOT technologies can get the advancement of shared mobility, specifically for car-sharing and leasing. This research produced a conceptual design and architecture for blockchain-IOT-based car-sharing platform based on key design principles. Study tells that blockchain, as one possible technology, can advance car-sharing by facilitating intercompany collaboration between several stakeholders within car sharing and leasing and eliminating the need for trust to some extent. The design of the underlying blockchain- based platform depends on the five design principles, namely security and privacy, authenticity, traceability and reliability, scalability, and interoperability.  A reservation scheme has been proposed for station-based two-way car-sharing systems that leverages the temporal flexibility of drivers. By combining reservations with flexibility, the scheme can benefit both the car-sharing owner and the drivers by improving the management of reservation information. Presently, car-sharing systems do not prioritize reservations, meaning the first person to reserve a vehicle gets to use it until no vehicles are available at a given station during a specific period. To ensure customer satisfaction and vehicle availability, car-sharing operators may need to maintain an oversized fleet at multiple stations, which can be costly.  An algorithm has been developed to address the use of autonomous vehicles in exchange terminals, with the ability to adjust dimensions and geometric designs. The algorithm proposed six different geometric designs, which were modeled using simulation software and the NIC algorithm was employed. The system simulated a real-world scenario of an interchange with a slightly modified geometric design to provide smoother entry to the interchange terminal. To evaluate the system's performance, several assumptions were made, and the six designs were tested against five different traffic demands.
The interchange throughput and delay were found to be impacted by different volume ratios. The best performing design for the highest throughput and lowest delay varied depending on the volume ratio. For instance, when the turning ratio was 30% and through ratio was 70%, the TO design provided the best performance, while the WTOS and WTTS designs had the lowest performance. When the turning ratio and through ratio were equal, the TTOS design demonstrated improved performance, while the WTOS and WTTS designs had the lowest performance. Finally, for the high turning volume of 70% and through volume of 30%, the TTTS design provided better performance, while the WTOS and WTTS designs had the lowest performance. eliminating the need for trust to some extent.
The design of underlying blockchain- based platform depends on the five design principles, namely security and privacy, authenticity, traceability and reliability, scalability, and interoperability.
Blockchain is a type of distributed ledger that provides benefits such as decentralization, integrity, and resistance to tampering. There are three main categories of blockchains: public (also known as permissionless), consortium, and private (also known as permissioned) blockchains. Public blockchains allow each node to maintain a ledger, participate in consensus, and read and write data, but this can lead to slow consensus and high maintenance costs. Additionally, any node can join or leave the network without authorization, making it unsuitable for a car- sharing system where user privacy is crucial. In contrast, consortium and private blockchains only allow approved nodes to access the ledger, with private blockchains being controlled by approved organizations and having centralized properties. Consortium blockchains offer efficient consensus time and maintenance costs while operating under approved groups. Therefore, we proposed a car-sharing scheme using a consortium blockchain.
B. Elliptic Curve Cryptosystem (ECC)
Elliptic Curve Cryptography (ECC) is a widely used public key cryptosystem that is based on elliptic curves. It is favored for cryptographic protocols because it provides the same level of security as other encryption methods, but with shorter key lengths. In ECC, an elliptic curve is defined as Ep(r, s): y2 = x 3 + ax2 + b over a prime finite field Zq, where q is a large prime, and (r, s) ∈ Zq, and 4a 3 + 27b 26= 0 (mod s). A point R is located on Ep(r, s). The security of ECC is based on two uncontrollable problems:
C. Adversary Model
The Dolev-Yao (DY) attack model is used to determine the capabilities of an adversary. This model is widely accepted as a standard in evaluating protocol security. The adversary is assumed to have the following abilities:
IV. SYSTEM MODEL
The authentication scheme suggested for a car-sharing system was designed around a blockchain network comprising five entities, including Trust Authority, Station, Owners, Vehicles, and Users. Trust Authority is responsible for creating the system and issuing credentials and pseudo identities to users and vehicle owners. Stations have data storage and processing functions and are responsible for organizing consortium blockchains. Users submit car-sharing requests through stations to owners, and after authentication, receive an access code to unlock and operate the vehicle.
The communication flows on the proposed car-sharing system are depicted as follows:
a. The user and owner submit their actual ID and license to the Trust Authority (TA) to obtain pseudo-IDs and credentials for registering with the car-sharing system.
b. Users and owners register their pseudo-IDs, public keys, and shared vehicle information at the stations to use the car-sharing services.
c. A user uses their mobile device to request access to a shared car from a station. The station verifies the user's identity and informs the owner of the request. The owner then generates an access code for the shared car and sends it to the user and the car through the station.
d. The user uses their saved access code on their mobile device to access the shared car.
Car-sharing systems have become popular in urban areas as a solution to transportation issues. However, the centralized structure of traditional vehicle-sharing systems and communication through public channels create security concerns. To address these issues, this study proposes a secure decentralized car-sharing model and authentication scheme that uses blockchain to ensure data integrity and provide a decentralized service. A pseudonym for users is also implemented to protect their privacy. The proposed protocol offers secure mutual authentication between users, stations, and owners, and is secure against various types of attacks, including replay and man-in-the-middle attacks. The protocol provides anonymity, confidentiality, and mutual authentication, and has been subjected to informal security analysis. The proposed protocol is efficient and can be implemented in a blockchain-based car- sharing system. Future work includes simulation development and application of the protocol to a real vehicle-sharing system. In conclusion, the proposed decentralized car-sharing system with a secure authentication scheme provides an innovative solution to the security and privacy concerns associated with traditional vehicle-sharing systems. By utilizing blockchain technology and pseudonyms for user privacy, the proposed protocol ensures the integrity and confidentiality of shared data. The BAN logic analysis and AVISPA simulation demonstrate the protocol\'s effectiveness against common security threats, making it a reliable and secure option for decentralized car- sharing services. With further development and testing, the proposed protocol could be implemented in real-world car- sharing systems, offering a more efficient and secure alternative to traditional centralized systems.
