Abstract: The benefits of Cloud computing include reduced costs, high reliability, as well as the immediate availability of additional computing resources as needed. Despite such advantages, Cloud Service Provider (CSP) consumers need to be aware that the Cloud poses its own set of unique risks that are not typically associated with storing and processing one’s own data internally using privately owned infrastructure. Recent years have seen a number of such incidents occur, whereby customer data hosted on the Cloud has been leaked. The ideal solution to achieving an optimal balance of data security and functionality within the Cloud involves the CSP having the ability to search and operate on data while it is in encrypted form.
New techniques such as Fully Homomorphic Encryption and Searchable Encryption have arisen to make this a reality. Fully-Homomorphic Encryption supports computations over data in encrypted form but an efficient Fully-Homomorphic Encryption remains someway off. Searchable Encryption however, despite being a relatively obscure form of Cryptography is now at the point that it can be deployed and used within the Cloud. Searchable Encryption can allow CSP customers to store their data in encrypted form, while retaining the ability to search that data without disclosing the associated decryption keys to CSPs. Symmetric Search Encryption (SSE) represents one of the few forms of Searchable Encryption that is achievable using established standardised encryption algorithms. This talk will discuss a Searchable Symmetric Encryption scheme which is efficient enough to be deployed in a Cloud environment to achieve industry acceptable search speeds whilst maintaining Data Privacy.
