Cloud-Based Lightweight RFID Healthcare Privacy Protection Protocol

Researchers and engineers have paid more attention to cloud-based application systems, whose features are virtualization and services provisioning. Fortunately the technology can be just right to healthcare. Meanwhile, security has also become more challenging. Although many cloud-based RFID authentication protocols have been proposed, some of them only improve the function and performance without considering security and privacy, and most of them are heavyweight. It is not appropriate in the field of healthcare, because improving the trustworthiness of anonymous virtual computing services should be the primary consideration. So we propose a lightweight privacy protection authentication scheme which can be applied in the cloud environment, in the scheme, service providers could be anonymous or unknown to the application consumer. Assuming many hospitals build a cloud platform together, the information of patient and his physician will be stored anonymously in the cloud. Patient can go to a doctor in any one hospital with a unique RFID tag. Reader may be fixed or mobile; Readers read tags and upload collected data to the cloud for further processing in real time. Compared with some traditional schemes, our scheme is lightweight, cost-efficient, elastic scalability, real-time, and easy to against synchronization attack.
