Attribute-based encryption for fine-grained access control of encrypted data
As more sensitive data is shared and stored by third-party sites on the Internet, there will be a need to encrypt data stored at these sites. One drawback of encrypting data, is t...

Attribute-based encryption with non-monotonic access structures
We construct an Attribute-Based Encryption (ABE) scheme that allows a user’s private key to be expressed in terms of any access formula over attributes. Previous ABE schemes wer...

Privacy in Encrypted Content Distribution Using Private Broadcast Encryption
In many content distribution systems it is important both to restrict access to content to authorized users and to protect the identities of these users. We discover that current s...

Fully Homomorphic Encryption with Polylog Overhead
We show that homomorphic evaluation of (wide enough) arithmetic circuits can be accomplished with only polylogarithmic overhead. Namely, we present a construction of fully homomorp...

Comparison-based encryption for fine-grained access control in clouds
Access control is one of the most important security mechanisms in cloud computing. However, there has been little work that explores various comparison-based constraints for regu...
