Fully Homomorphic Encryption from Ring-LWE and Security for Key Dependent Messages
We present a somewhat homomorphic encryption scheme that is both very simple to describe and analyze, and whose security (quantumly) reduces to the worst-case hardness of problems ...

Smooth Projective Hashing and Password-Based Authenticated Key Exchange from Lattices
Abstract. We describe a public-key encryption scheme based on lattices — specifically, based on the hardness of the learning with error (LWE) problem — that is secure against ...

Formal Security Proofs for a Signature Scheme with Partial Message Recovery
The Pintsov-Vanstone signature scheme with partial message recovery (PVSSR) is a variant of the Schnorr and Nyberg-Rueppel signature schemes. It produces very short signatures on ...

Identity-Based Threshold Proxy Signature from Bilinear Pairings
Abstract. Delegation of rights is a common practice in the real world. We present two identitybased threshold proxy signature schemes, which allow an original signer to delegate he...

Chameleon Signatures
Abstract. Chameleon signatures simultaneously provide the properties of nonrepudiation and non-transferability for the signed message. However, the initial constructions of chamele...
