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.

Category / Keywords: searchable encryption, access control, signatures with delayed verifiability
