"Privacy-Preserving Multi-Keyword Searchable Encryption for Distributed" by Xueqiao Liu, Guomin Yang et al.

Abstract
As cloud storage has been widely adopted in various applications, how to protect data privacy while allowing efficient data search and retrieval in a distributed environment remains a challenging research problem. Existing searchable encryption schemes are still inadequate on desired functionality and security/privacy perspectives. Specifically, supporting multi-keyword search under the multi-user setting, hiding search pattern and access pattern, and resisting keyword guessing attacks (KGA) are the most challenging tasks. In this article, we present a new searchable encryption scheme that addresses the above problems simultaneously, which makes it practical to be adopted in distributed systems. It not only enables multi-keyword search over encrypted data under a multi-writer/multi-reader setting but also guarantees the data and search pattern privacy. To prevent KGA, our scheme adopts a multi-server architecture, which accelerates search response, shares the workload ....

Delivering an effective cyber security strategy within healthcare

Delivering an effective cyber security strategy within healthcare
Kevin Curran, IEEE senior member and professor of cyber security at Ulster University, discusses the delivery of an effective cyber security strategy within healthcare
An effective strategy is vital to long-term protection of healthcare data.
Just a few months ago, the UK Government announced a new NHS England app that will enable patients to book appointments directly with their General Practitioners (GPs), as well as repeat prescriptions and view their own personal medical files. Most healthcare organisations have been trying to digitise their services for years in order to reduce the administrative workload and improve overall patient care. The benefits of such a move are plain to see, with the internet of things (IoT) being able to influence several areas including clinical operations, in-patient monitoring, medication management and ....
