Overview

With the advent of cloud computing, many companies and individuals outsource their data and computation to the public cloud. E-medical record is a sensitive medical data which when stored in public cloud brings a variety of risks like of data leakage to the untrusted cloud server, unauthorized access or modification operations. To assure the confidentiality of the data, the data owner needs to encrypt the sensitive data before uploading to the third party. Yet, issues like encrypted data search, flexible access and control on sensitive data have also remained the most significant challenges.

This project will investigate a novel searchable encrypted sensitive data like e-medical framework for multi-client which provides both confidentiality and searchability. The project will focus on both the public key setting and the symmetric key setting depending on the different usecases. Also the project investigates on enabling the secure data update of the encrypted database by leveraging a secure dynamic searchable encryption.
