Deduplication is a popular technique widely used to save storage spaces in the cloud. To
achieve secure deduplication of encrypted files, Bellare et al. formalized a new …

Cloud data deduplication removes redundant data blocks or files and keeps only one copy
in the cloud storage server. In order to improve on security, we need to encrypt data files and …

With growing popularity of cloud storage, the number of users of outsourcing data to cloud
servers has increased dramatically. On the one hand, the rapidly increasing volume of data …

Data storage in the cloud is becoming widespread. Deduplication is a key mechanism to

Deduplication is a widely used technique for reducing storage space of cloud service
providers. Yet, it is unclear how to support deduplication of encrypted data securely until the …

In this paper, we propose a novel secure role re-encryption system (SRRS), which is based
on convergent encryption and the role re-encryption algorithm to prevent the privacy data …

Cloud storage offers cost effective storage to the users dynamically. Corporate and private
users upload their sensitive data items to the cloud storage. But mostly the data stored in the …
