An Effective Public-key Authenticated Searchable Encryption for Protecting Sensitive data in Healthcare IoT

The practice of conveying medical records to either a Third-Party Cloud Service (TCS) for backups has become increasingly popular in recent decades at least as the healthcare Internet of things has expanded. However, when used in many environments, a few little PAEKS schemes also have security issues. People proposed a novel, efficient, but also effective PAEKS scheme in this article. The Diffie-Hellman pow consensus concept is used in this scheme to generate a secret key known only to the receiver and to the sender. We show that our scheme is completely risk-free against inside keyword various attacks in several co-environments when the Cloudera Diffie-Hellman assumption is used. From the analysis, it shows that proposed method achieved better results in terms of accuracy (96.8%), precision (95.2%), recall (95.8%) f1-score (95.5%), memory utilization (80 MB) and execution time (0.7 sec) respectively.
