Architectural framework of a group key management system for enhancing e‐healthcare data security

Presently, patient information quality, security, and privacy are important issues in the healthcare sector for promoting high standards of patient care. The adoption of digital patient files, enhanced regulation, health practitioner consolidation, and the increasing want for information exchange between patients, providers and payers need better information security. A novel master‐key management technique has been proposed for the purpose of managing the keys which enhance the healthcare information security and the multi‐key server approach is used for balancing the load in a key server, which provides quick access to electronic health records. This research focuses on the development of a new architecture of the large‐scale e‐healthcare group key management system to facilitate a secured and reliable assistance among the healthcare enterprises and service providers. The authors have tested in a group of healthcare users joining and leaving dynamically and validated by applying it to virtual servers, which shows that the rekeying overhead, threats and computational cost of the healthcare network system are minimised when compared with the existing schemes. This research work is driven by the investigation of different healthcare enterprise systems, consultations with the hospital, data centre, and medical device firm employees and sourcing industry knowledge from thought leaders.
