The shuffle index provides confidentiality guarantees for accesses to externally outsourced data. In this paper, we extend the shuffle index with support for access control, that is, for enforcing authorizations on data. Our approach bases on the use of selective encryption and on the organization of data and authorizations in two shuffle indexes. Our proposal enables owners to regulate access to their data supporting authorizations allowing different users access to different portions of the data, while at the same time guaranteeing confidentiality of access.

Abstract
The shuffle index provides confidentiality guarantees for accesses to externally outsourced data. In this paper, we extend the shuffle index with support for access control, that is, for enforcing authorizations on data. Our approach bases on the use of selective encryption and on the organization of data and authorizations in two shuffle indexes. Our proposal enables owners to regulate access to their data supporting authorizations allowing different users access to different portions of the data, while at the same time guaranteeing confidentiality of access.File | Dimensione del file | Formato | |
