An increasing number of patients in the e-healthcare system can obtain top-notch medical services by sharing encrypted personal healthcare data (PHRs) with doctors or institutions involved in medical research. However, one of the main issues is that encrypted PHRs make it impossible to conduct efficient information searches. cutting back on the data usage. Another issue is that delivering medical care requires a doctor to be constantly accessible online, which may be too expensive for some professionals to afford (for example, to occasionally be absent). In this work, a brand-new, useful, secure proxy searchable re-encryption method is developed, allowing medical professionals to monitor and conduct research on patient health records remotely in an efficient and secure manner. Our DSAS scheme ensures the privacy and secrecy thanks to the following features: the doctor-in-charge, Alice, has the ability to delegate medical choices. These characteristics of PHRs ensure that patient healthcare records gathered by the devices are encrypted before uploading to the cloud server. Only authorized doctors or research institutes have access to PHRs. The cloud server limits the accessibility of information since Bob (the doctor-in-agent) or a certain research institution can utilize it for study. We formalize the idea of security and show the security of our system. Finally, performance analysis shows how effective our plan.
