“…The main goal of the Island splitting protocol is to provide a mechanism to limit the maximum size of the Islands. The goal is to create Islands with acceptable performances and no more than 100 validators in the cluster [17,18]. This protocol defines the maximum numbers of validators in an Island in order to avoid the network congestion from voting message exchanges.…”

The increased number of Internet services and the exposure of the personal information to the public network, create a problem with the privacy of the personal data. This problem is extremely impactful in the healthcare systems where the sensitive medical data circulate in the network. The emerging Blockchain technologies offer properties and tools for better personal data access management. The integration of the Blockchain technologies into the healthcare systems can provide better data privacy. However, beside the attractive properties, the current Blockchain technologies cannot achieve sufficient scalability to serve a global public healthcare system and cannot provide compatibility with the GDPR and HIPAA regulations. To overcome these limitations, this paper introduces new deducted Blockchain-based public healthcare system, the BloHeS, with main focus on several functional entities, such as optimal consensus mechanism, better storage organization, improved network organization and compatibility with GDPR and HIPAA regulations. It also defines a procedure for patient-centric data access management, protocols for Island management and new block structure.

“…A vehicle in the vicinity receiving such reports computes each report's credibility which is exponentially decreased with the distance to the reporting vehicle. Based on the set of computed credibility, a receiving vehicle computes the aggregated credibility of the event by using the Bayesian inference in [19] and the gradient boosting technique in [20]. Then the receiving vehicles share the feedback with the nearby RSU to update the TV of the reporter and save it into the BC.…”

<p>In VANET, although data sharing among vehicles improves safety and trafﬁc, malicious data providers might share false information to compromise its effectiveness. One typical solution to address this issue is to manage the trustworthiness of data providers by using feedback received from data users quantifying the veracity of the shared data. However, data users might behave maliciously and share untruthful feedback. This paper introduces TrCoin, a blockchain-based trust management system, for VANET which tackles both fake data and untruthful feedback. TrCoin uses an honesty value calculation algorithm to distinguish honest from malicious data users and ﬁlters out the feedback shared by the malicious data users. TrCoin then runs a trust value calculation algorithm to compute the trust values of data providers based on the truthful feedback shared by honest data users. Extensive simulations are conducted to demonstrate the effectiveness of TrCoin under various attack scenarios with false data injection and untruthful feedback.</p>

Intelligent Proof-of-Trustworthiness-Based Secure Safety Message Dissemination Scheme for Vehicular Ad Hoc Networks Using Blockchain and Deep Learning Techniques

et al. 2023

Vehicular ad hoc networks have emerged as the main building block for the future cooperative intelligent transportation system (cITS) to improve road safety and traffic efficiency and to provide passenger comfort. However, vehicular networks are decentralized, characterized by high mobility and dynamicity, and vehicles move in a hostile environment; such characteristics make VANET applications suffer many security and communication issues. Recently, blockchain has been suggested to solve several VANET issues including the dissemination of trustworthy life-threatening information. However, existing dissemination schemes are inefficient for safety messages and are vulnerable to malicious nodes and rely on the majority of honest assumptions. In the VANET context, adversaries may collude to broadcast false information causing serious safety threats. This study proposes an intelligent proof-of-trustworthiness-based secure safety message dissemination scheme (PoTMDS) to efficiently share only trustworthy messages. The consistency and plausibility of the message were evaluated based on a predictive model developed using a convolutional neural network and signal properties such as the received signal strength and angle of arrival. A blockchain-based data dissemination scheme was developed to share critical messages. Each vehicle calculates the proof of trustworthiness of the disseminated messages by comparing the received message with the output of the prediction model. The results showed that the proposed scheme reduced the consensus delay by 58% and improved the detection accuracy by 7.8%. Therefore, the proposed scheme can have an important role in improving the applications of future cITS.
