MicroSCOPE: Enabling access control in searchable encryption with the use of attribute-based encryption and SGX

Abstract

Secure cloud storage is considered as one of the most important problems that both businesses and end-users take into account before moving their private data to the cloud. Lately, we have seen some interesting approaches that are based either on the promising concept of Symmetric Searchable Encryption (SSE) or on the well-studied field of Attribute-Based Encryption (ABE). Our construction, MicroSCOPE, combines both ABE and SSE to utilize the advantages of each technique. Finally, we enhance our construction with an access control mechanism by utilizing the functionality provided by SGX.
