云医疗体系中基于属性加密的数据共享方案
Data Sharing Scheme Based on Attribute Encryption in Cloud Medical System
摘要
Abstract
With the application and development of cloud-based healthcare systems,ensuring the security and effective sharing of Electronic Health Record(EHR)data has become a critical issue.To address this problem,a scheme supporting fine-grained search,attribute revocation,and outsourced encryption and decryption of EHR data sharing has been proposed.The advantages of this solution are as follows:Firstly,using ciphertext policy attribute-based encryption technology,patients can have full control over their EHR data and achieve fine-grained sharing of EHR data.Secondly,the addition of attribute revocation functionality ensures timely and effective protection of patient privacy.Thirdly,by combining searchable encryption techniques with attribute-based encryption techniques,the scheme achieves more fine-grained search capabilities.Lastly,by outsourcing the computation of attribute-related partial encryption and decryption,as well as the generation of keyword ciphertext,to the cloud server,the computational overhead for system users is reduced.In addition,through security analysis,performance comparison,and experimental analysis,the proposed scheme has been shown to enable healthcare institutions in cloud-based healthcare systems to securely and effectively share EHR data without compromising patient priva-cy.关键词
