Improved Delegation of Computation Using Fully Homomorphic Encryption
Following Gennaro, Gentry, and Parno (Cryptology ePrint Archive 2009/547), we use fully homomorphic encryption to design improved schemes for delegating computation. In such schem...

Applying Fujisaki-Okamoto to Identity-Based Encryption
The Fujisaki-Okamoto (FO) conversion is widely known to be able to generically convert a weak public key encryption scheme, say one-way against chosen plaintext attacks (OW-CPA), t...

Structure Preserving CCA Secure Encryption and Its Application to Oblivious Third Parties
In this paper we present the first public key encryption scheme that is structure preserving, i.e., our encryption scheme uses only algebraic operations. In particular it does not...

Revocation Systems with Very Small Private Keys
In this work, we design a method for creating public key broadcast encryption systems. Our main technical innovation is based on a new “two equation” technique for revoking us...

Privacy-Aware Attribute-Based Encryption with User Accountability
As a new public key primitive, attribute-based encryption (ABE) is envisioned to be a promising tool for implementing fine-grained access control. To further address the concern o...
