This document proposes a framework for securely storing personal health records (PHRs) in cloud computing using attribute-based encryption (ABE). The framework divides users into security domains to reduce complexity in key management for PHR owners and users. It exploits multi-authority ABE to guarantee patient privacy. The proposed scheme also enables dynamic access policies and file attributes as well as efficient user/attribute revocation and emergency access. Analysis and experiments show the security, scalability and efficiency of the scheme.

SCALABLE AND SECURE SHARING OF PERSONAL HEALTH RECORDS IN
CLOUD COMPUTING USING ATTRIBUTE-BASED ENCRYPTION
ABSTRACT:
Personal health record (PHR) is an emerging patient-centric model of health information
exchange, which is often outsourced to be stored at a third party, such as cloud providers.
However, there have been wide privacy concerns as personal health information could be
exposed to those third party servers and to unauthorized parties. To assure the patients’ control
over access to their own PHRs, it is a promising method to encrypt the PHRs before outsourcing.
Yet, issues such as risks of privacy exposure, scalability in key management, flexible access, and
efficient user revocation, have remained the most important challenges toward achieving fine-
grained, cryptographically enforced data access control.
In this paper, we propose a novel patient-centric framework and a suite of mechanisms for data
access control to PHRs stored in semitrusted servers. To achieve fine-grained and scalable data
access control for PHRs, we leverage attribute-based encryption (ABE) techniques to encrypt
each patient’s PHR file. Different from previous works in secure data outsourcing, we focus on
the multiple data owner scenario, and divide the users in the PHR system into multiple security
domains that greatly reduces the key management complexity for owners and users. A high
degree of patient privacy is guaranteed simultaneously by exploiting multiauthority ABE. Our
scheme also enables dynamic modification of access policies or file attributes, supports efficient
on-demand user/attribute revocation and break-glass access under emergency scenarios.
Extensive analytical and experimental results are presented which show the security, scalability,
and efficiency of our proposed scheme.

The document proposes a framework for securely sharing personal health records (PHRs) stored in the cloud using attribute-based encryption (ABE). It aims to achieve fine-grained access control over PHRs while addressing challenges like privacy risks, complex key management, and user revocation. The framework divides users into multiple security domains to reduce complexity and uses multi-authority ABE to guarantee patient privacy. Access policies and file attributes can also be dynamically modified. Experimental results demonstrate the security, scalability and efficiency of the proposed scheme.

This document proposes a framework for securely storing personal health records (PHRs) in the cloud. It aims to achieve fine-grained access control and protect privacy. The framework uses attribute-based encryption to encrypt each patient's PHR file under access policies. This allows patients to selectively share records with users based on their attributes without knowing a full user list. It also divides the system into public and personal domains for different user access needs. Analytical and experimental results show the framework provides data confidentiality, revocation of access rights, write access control, and scalability.

This document proposes a cloud-based architecture for wireless sensor networks used in e-health applications. It discusses three key components: 1) a wireless sensor network that collects patient health data, 2) monitoring applications for healthcare professionals to access stored data, and 3) a Healthcare Authority that specifies security policies. It then proposes using attribute-based encryption and symmetric encryption to encrypt health data and implement access control policies while outsourcing storage to the cloud. Performance analysis shows the proposed approach reduces overhead compared to solely using attribute-based encryption.

This document proposes a framework for securely sharing personal health records (PHRs) stored in the cloud. It uses attribute-based encryption to encrypt PHR files under access policies. It divides users into public and personal domains to address key management challenges at scale. In the public domain, multiple attribute authorities distribute keys to manage professional users' role attributes without a single point of failure. Owners specify access policies during encryption. The personal domain allows owners to directly manage access for personal users. The framework supports dynamic policy updates, break-glass access, and an efficient revocation scheme.
