Achieving Secure and Efficient Dynamic Searchable Symmetric Encryption Over Medical Cloud Data

Abstract

The ability to search seamlessly through personalized data has become a major requirement for the usability of a cloud computing infrastructure. And with the assumption that cloud storage servers remain “honest but curious” due to the possibility of information theft, there is the ever-present need to use cryptographic means to encrypt data in the cloud. Achieving Secure and Efficient Dynamic Searchable Symmetric Encryption over Medical Cloud Data In the midst of these requirements, however, it is also difficult to search data once it has been encrypted and sent for storage to a remote server.

Introduction

Achieving Secure and Efficient Dynamic Searchable Symmetric Encryption Over Medical Cloud Data Searchable Symmetric Encryption (SSE) is a cryptographic scheme that involves the ability to store encrypted information on an outsourced storage server (i.e. local or remote storage) and the information owner still maintains the ability to search the stored data without full access to the stored data by the storage server owner. The need to adopt this type of data storage has evolved from the assumption that outsourced storage servers tend to be “honest but curious” as there is the possibility for a cloud service provider to snoop for various purposes through the stored data.
