Searchable Symmetric Encryption: Review and evaluation

Searchable Symmetric Encryption (SSE) allows a user to search over their encrypted data on a third party storage provider privately. There are several existing SSE schemes have been proposed to achieve this goal. This paper concerns with three currentSSE schemes, which are the Practical Techniques for Searches in Encrypted Data (PTSED), the Secure Index(SI), and the Fuzzy Keyword Search over Encrypted Data in the Cloud Computing (FKS-EDCC).The objective of this paper is to introduce a review of the three schemes with a discussion in the advantages and disadvantages of each.This paper also implements aprototype over an SI-based secure file searching system using java language. The performance of the system has been evaluated and discussed according to the false-positive rate. Keywords: Searchable Symmetric Encryption (SSE), Practical Techniques for searches in encrypted Data (PTSED), Secure index (SI), Fuzz Keyword Search over Encrypted Data in Cloud Computing (FKS-EDCC).
