In the traditional electronic health record (EHR) management system, each medical service center manages their own health records, respectively, which are difficult to share on the different medical platforms. Recently, blockchain technology is one of the popular alternatives to enable medical service centers based on different platforms to share EHRs. However, it is hard to store whole EHR data in blockchain because of the size and the price of blockchain. To resolve this problem, cloud computing is considered as a promising solution. Cloud computing offers advantageous properties such as storage availability and scalability. Unfortunately, the EHR system with cloud computing can be vulnerable to various attacks because the sensitive data is sent over a public channel. We propose the secure protocol for cloud-assisted EHR system using blockchain. In the proposed scheme, blockchain technology is used to provide data integrity and access control using log transactions and the cloud server stores and manages the patient’s EHRs to provide secure storage resources. We use an elliptic curve cryptosystems (ECC) to provide secure health data sharing with cloud computing. We demonstrate that the proposed EHR system can prevent various attacks by using informal security analysis and automated validation of internet security protocols and applications (AVISPA) simulation. Furthermore, we prove that the proposed EHR system provides secure mutual authentication using BAN logic analysis. We then compare the computation overhead, communication overhead, and security properties with existing schemes. Consequently, the proposed EHR system is suitable for the practical healthcare system considering security and efficiency.

SEC-C-U: The Security of Intensive Care Unit Medical Devices and Their Ecosystems

2020

An intensive care unit (ICU) is dedicated to caring for patients whose medical condition places them at high risk of mortality or serious morbidity. ICU medical devices (ICUMDs) are used to closely monitor, stabilize, and treat ICU patients who are often unconscious and rely almost solely on ICUMDs. ICUMDs have become more autonomous, with a range of components, connectivity to external devices, and functionalities, opening the door to cyber-attacks. We present a taxonomy based on the functionality of 19 widely used ICUMDs, providing an explanation of each device's medical role, properties, interactions, and how they impact each other's security. We provide an extensive survey of 16 possible attacks aimed at ICUMDs and assess each device's vulnerability. We also create an ecosystem graph describing the roles and interactions of the players of each ICU sub-department. For each device type we produce a unique attack flow diagram that presents the most vulnerable vectors and components within the ecosystem. Finally, we survey relevant security mechanisms and map their coverage for the attacks, identifying existing gaps. We show that current security mechanisms generally fail to provide protection, covering just 12.5-56.3% of the attacks against ICUMDs, leaving the devices and the patients vulnerable.

“…Blockchain's criteria of no-human intervening during a process of transaction made it widely applied in various field. As an example, in public services [22]- [24], healthcare [25]- [27], IoT [12], [28] rather than only on the financial system. Nowadays, usage of blockchain is increasing as its source is made as an open-source, which mean anyone can use the entire history of it or modify it legally without need of paying for the service [29].…”
