- Abstract
Rekeying is a common way to protect outsourced data against key compromise and to enable data owners to enforce access control on their data. However, existing rekeying schemes are difficult to apply to the encryption dedu plication system which uses message-locked encryption for allowing the server to perform deduplication on users' outsourced data. In this paper, we propose a new rekeying scheme named REEDBN, which leverages a proxy re-encryption based on NTRU to reduce the communicational cost for the system and the com putational overheads for clients during rekeying. We implement the prototype of our scheme and conduct testbed experiments. The results show that our system has much less communicational effort and computational overhead for clients than the previous scheme. Users can even rekey their outsourced data on some mobile terminals which only have limited computation power.
