Attribute-Based Storage Supporting Secure Deduplication of Encrypted
Data
Abstract
Attribute-based encryption (ABE) has been widely used in cloud computing where a data provider outsources his / her encrypted data to a cloud service provider and can share data with users with specific credentials (or attributes). Attribute-Based Storage Supporting Secure Deduplication of Encrypted Data However, the standard ABE system does not support secure deduplication, which is crucial to eliminating duplicate copies of identical data to save storage space and network bandwidth.
Attribute-Based Storage Supporting Secure Deduplication of Encrypted Data Our system has two advantages compared to previous data deduplication systems. First it achieves the standard notion of semantic data confidentiality security while existing systems achieve this only by defining a weaker notion of security.

Conclusion
Attribute-based encryption (ABE) has been widely used in cloud computing where data providers outsource their encrypted data to the cloud and can share the data with users possessing specified c redentials. On the other hand, deduplication is an important technique to save the storage space and network bandwidth, which eliminates duplicate copies of identical data. However, the standard ABE systems do not support secure deduplication, which makes them costly to be applied in some commercial storage services.
