Preserving data privacy with Searchable Symmetric Encryption

Abstract

New techniques such as Searchable Encryption are being deployed to enable data to be encrypted online. Searchable Encryption is now at the point that it can be deployed and used within the Cloud. In the Cloud, Searchable Encryption has the ability to allow CSP customers to store their data in encrypted form, while retaining the ability to search that data without disclosing the associated decryption key(s) to CSPs that is, without compromising data security on the Server. We present an SSE scheme and evaluate the efficiency of storing and retrieving data from the cloud. The results showed that carrying out a task using SSE is directly proportional to the amount of information involved.
