Core Concepts

The author proposes a framework combining CPABE and OAuth2.0 to enhance EHR sharing efficiency, addressing data security and access control challenges in cloud-based healthcare services.

Abstract

The study introduces a CPABE and OAuth2.0 framework to improve EHR sharing efficiency, addressing vulnerabilities in cloud-based healthcare services. The proposed framework aims to provide secure access control while enabling efficient data sharing among various stakeholders in the healthcare sector. By integrating CPABE for encryption and access control with OAuth2.0 for authorization, the framework ensures secure and controlled sharing of sensitive health records across multiple platforms.
The research highlights the importance of practical adaptability in implementing secure frameworks for EHR sharing, emphasizing the need to bridge gaps in data security and resource control within cloud environments. Through simulation analysis, the study demonstrates the superior performance of the proposed framework compared to existing approaches, particularly in key generation, encryption, and decryption phases.
Overall, the study contributes valuable insights into enhancing data security and access control mechanisms in cloud-based healthcare systems through innovative frameworks like CPABE and OAuth2.0.

Stats

With recent elevated adaptation of cloud services in almost every major public sector, the health sector emerges as a vulnerable segment.
In this study, we have suggested a CPABE and OAuth2.0 based framework for efficient access-control and authorization respectively to improve the practicality of EHR sharing across a single client-application.
Our implementation of the suggested framework along with its analytical comparison signifies its potential in terms of efficient performance and minimal latency.
Electronic Health uses digital resources to transcend geographical obstacles and provide access to healthcare solutions.
Encryption is amongst the most effective approaches for protecting EHRs in the cloud as it ensures security since files are encrypted before transmission to the cloud but are decrypted following their retrieval.
Attribute-Based Encryption (ABE) propose alternatives to data exchange quandary.

Deeper Inquiries

How can blockchain technology enhance the proposed CPABE-OAuth2.0 framework?

Blockchain technology can enhance the proposed CPABE-OAuth2.0 framework by providing additional layers of security, transparency, and decentralization. By incorporating blockchain into the framework, data integrity and immutability can be ensured through distributed ledger technology. Smart contracts on a blockchain network can automate access control processes based on predefined rules, enhancing efficiency and reducing human error. Additionally, blockchain's decentralized nature eliminates single points of failure and enhances trust among parties involved in sharing electronic health records.

What are potential challenges when integrating attribute-based encryption with open authorization protocols?

One potential challenge when integrating attribute-based encryption (ABE) with open authorization protocols like OAuth 2.0 is ensuring seamless compatibility between the two systems. ABE relies on attributes to define access policies for encrypted data, while OAuth focuses on granting access tokens based on user permissions. Aligning these different approaches to access control requires careful coordination to avoid conflicts or inconsistencies in authorization mechanisms.
Another challenge is managing complex access policies that involve multiple attributes across different systems. Ensuring that attribute sets defined in ABE align with user roles or scopes defined in OAuth can be challenging, especially when dealing with diverse user groups or organizations with varying levels of access requirements.
Furthermore, maintaining scalability and performance while integrating ABE with OAuth may pose challenges due to increased computational overhead from cryptographic operations associated with ABE schemes.

How can decentralized attribute-based encryption improve data security in healthcare systems?

Decentralized attribute-based encryption (ABE) offers several advantages for improving data security in healthcare systems:

Enhanced Privacy: Decentralized ABE allows for fine-grained access control over sensitive health records based on multiple attributes without relying on a central authority for key management. This ensures that only authorized users with specific attributes can decrypt and access patient information.

Data Integrity: By leveraging a decentralized network such as a blockchain, decentralized ABE provides tamper-proof storage of encrypted health records along with immutable audit trails of data accesses and modifications.

Resilience Against Attacks: Decentralization reduces vulnerabilities associated with centralized servers storing critical healthcare data by distributing encrypted fragments across nodes within the network using secure multiparty computation techniques.

4Scalability: Decentralized architectures enable efficient scaling of healthcare systems as they grow by allowing seamless integration of new participants without compromising security or performance.
