A Comparative Analysis of Searchable Encryption Schemes using SGX
Hyundo Yoon, Junbeom Hur · 2020
Searchable encryption (SE) schemes enable users to search over encrypted data that are outsourced to untrusted cloud servers. Although many software-based SE schemes have been developed to improve security and functionality, most of them have limitations in terms of performance and security assumptions. In order to increase the efficiency, and guarantee query and data privacy, several SE schemes based on trusted execution environment (TEE) such as Intel SGX, ARM TrustZone have been proposed recently. In this paper, we investigate the existing SGX-based searchable encryption schemes, and conduct a comparative analysis of them.
