ENTRUST aims to develop a comprehensive framework for ensuring the security, privacy and operational assurance of Connected Medical Devices (CMDs) within healthcare organizations. By integrating Blockchain technology, ENTRUST introduces several innovative solutions that significantly enhance trust management. These innovations address key challenges in the healthcare sector, providing a robust foundation for managing CMDs securely and transparently. Through these advancements, ENTRUST aspires to set a new standard for medical device cybersecurity and trust management, driving forward the state-of-the-art in the healthcare industry.
One of the primary innovations Blockchain brings to ENTRUST is the creation of immutable trust records.
The decentralized ledgers of Blockchain ensure that every data transaction related to CMDs is permanently recorded and cannot be modified or deleted by any entity. This immutability is crucial for trust management as every action and update regarding CMDs is logged, creating a reliable history that different stakeholders can trust. Moreover, the permanent records in the Blockchain facilitate comprehensive tracking of CMDs throughout their lifecycle, enhancing accountability and transparency.
The decentralized nature of Blockchain eliminates the need for a central authority to manage and verify trust.
Instead, trust is established through consensus mechanisms and distributed nodes. Such decentralization reduces the single points of failure by distributing trust verification across multiple nodes, boosting the reliability and robustness of trust management. In addition, the decentralized verification of the Blockchain makes it more challenging for malicious entities to compromise the system, thereby enhancing the overall security of CMD management.
The advanced access control capabilities of Blockchain enable granular management of who can access data related to CMDs.
By implementing Attribute-Based Access Control (ABAC) mechanisms, the ENTRUST Blockchain ensures that only authorized entities can access sensitive information. The granular access control helps healthcare organizations comply with strict regulatory requirements by ensuring that data access is precisely managed and monitored. The ability of Blockchain to maintain a detailed provenance of CMDs enhances trust management by providing historical trust data. In this context, auditors can review the entire history of a CMD, including manufacturing, deployment and runtime phase to assess its trustworthiness. The historical trust data stored in the Blockchain can be used to perform advanced trust assessment and establish confidentiality and integrity within the ENTRUST Framework.
Blockchain facilitates secure data sharing and interoperability among diverse CMDs and healthcare systems.
In particular, the access control mechanisms that are employed by the Blockchain protect data during exchange, ensuring that it is shared securely between authorized entities. The standardized protocols provided by Blockchain enable seamless integration and communication between different CMDs and the ENTRUST Framework, regardless of their manufacturer or specifications. Also, smart contract mechanisms of the Blockchain enable the automation of trust management processes by recording data transactions in the ledgers.
In general, the introduction of Blockchain Infrastructure in the ENTRUST Framework aims to leverage the capabilities of Blockchain technology towards enabling the secure management of medical devices in ENTRUST by bringing to the forefront data integrity, confidentiality and provenance for enhancing the trustworthiness of CMDs.
