Dynamic Searchable Encryption with Access Control

Johannes Blömer and Nils Löken

Abstract

We present a searchable encryption scheme for dynamic document collections in a multi-user scenario. Our scheme features fine-grained access control to search results, as well as access control to operations such as adding documents to the document collection, or changing individual documents. The scheme features verifiability of search results. Our scheme also satisfies the forward privacy notion crucial for the security of dynamic searchable encryption schemes.

Note: The previous version of this report was expanded by a discussion of the type of ABE used in our construction, because this full version uses a different type of ABE than the conference version. Added a reference to the conference version.
