Abstract
The growing need to store, share, and manage medical and health records has resulted in electronic medical health sharing system (mHealth), which provides intelligent medical treatment for people. Attribute-based encryption (ABE) is regarded as a new cryptology to enhance fine-grained access control over encrypted sharing data in mHealth. However, some existing attribute-based mHealth systems not only violate the one-to-many application characteristics of attribute-based encryption mechanism but also destroy the anonymity of user. In this study, an efficient scheme is proposed to tackle the above defaults and offer two-way anonymity of data owner and data user by introducing a pseudoidentity. The computation of hidden access policy is reduced by removing the bilinear pairing, whereas the interaction between cloud storage and data user is avoided to save bandwidth during trapdoor generation. We also consider the temporal factor of the uploaded information by introducing access validity. Security and performance analyses show that the proposed scheme is efficient without reducing security.
Highlights
Given the rapid progress of cloud computing and mobile communication technology with ubiquitous mobile intelligent devices, the electronic medical health sharing system has been developed, which can provide intelligent healthcare services without temporal and spatial restrictions; mHealth allows patients to record body indicators and upload records, physicians to diagnose patients’ illness remotely, and researchers to explore medical records [1]. e application of mHealth reshapes healthcare services model [2]
If electronic health records (EHRs) are directly uploaded to the cloud for sharing, the information of patients and hospitals will inevitably be leaked to the cloud server and various users, which may cause hidden danger to patients’ health, threaten users’ life and health, and affect hospitals
In general Attribute-based encryption (ABE) schemes, the length of ciphertext, computation of encryption, and decryption are related with the number of attributes of data user, which restricts the use of this technique
Summary
Given the rapid progress of cloud computing and mobile communication technology with ubiquitous mobile intelligent devices, the electronic medical health sharing system (mHealth) has been developed, which can provide intelligent healthcare services without temporal and spatial restrictions; mHealth allows patients to record body indicators and upload records, physicians to diagnose patients’ illness remotely, and researchers to explore medical records [1]. e application of mHealth reshapes healthcare services model [2]. Is solution can help patients and data owners who do not want to disclose their identity preserve their anonymity whilst sharing their own EHRs. an infected patient who wants to upload personal encrypted records to provide information to scientific research, but due to some social factors, he/she does not want to let other users know his/her real identity [15]. In general ABE schemes, the length of ciphertext, computation of encryption, and decryption are related with the number of attributes of data user, which restricts the use of this technique. To resolve this defect, there are two main solutions.
