Abstract EN
Over the recent years, cloud storage services have become increasingly popular, where users can outsource data and access the outsourced data anywhere, anytime.
Accordingly, the data in the cloud is growing explosively.
Among the outsourced data, most of them are duplicated.
Cloud storage service providers can save huge amounts of resources via client-side deduplication.
On the other hand, for safe outsourcing, clients who use the cloud storage service desire data integrity and confidentiality of the outsourced data.
However, ensuring confidentiality and integrity in the cloud storage environment can be difficult.
Recently, in order to achieve integrity with deduplication, the notion of deduplicatable proof of storage has emerged, and various schemes have been proposed.
However, previous schemes are still inefficient and insecure.
In this paper, we propose a symmetric key based deduplicatable proof of storage scheme, which ensures confidentiality with dictionary attack resilience and supports integrity auditing based on symmetric key cryptography.
In our proposal, we introduce a bit-level challenge in a deduplicatable proof of storage protocol to minimize data access.
In addition, we prove the security of our proposal in the random oracle model with information theory.
Implementation results show that our scheme has the best performance.
