Abstract

One of the most important fundamental elements in guaranteeing data security is data access management. The two primary security components of data access control are typically authorisation and authentication. Data access control is the selective restriction of data access. First, we present an effective data access control mechanism for medical devices that are implanted in this study. Through a signcryption method with proxy reencryption (DAC-PRE), the protocol guarantees anonymous data access control and supports the user’s anonymity behaviour. The security is proven in oracle model. Our experimental analysis shows the proposed protocol has low computational cost.
