Construction of a Non-malleable Encryption Scheme from Any Semantically Secure One
There are several candidate semantically secure encryption schemes, yet in many applications non-malleability of encryptions is crucial. We show how to transform any semantically s...

Non-Malleable Non-Interactive Zero Knowledge and Adaptive Chosen-Ciphertext Security
We introduce the notion of non-malleable noninteractive zero-knowledge (NIZK) proof systems. We show how to transform any ordinary NIZK proof system into one that has strong non-m...

Construction of Threshold Public-Key Encryptions through Tag-Based Encryptions
In this paper, we propose a notion of threshold tag-based encryption schemes that simplifies the notion of threshold identity-based encryption schemes, and we show a conversion fro...

Chosen-Ciphertext Security from Identity-Based Encryption
Abstract. We propose a simple and efficient construction of a CCAsecure public-key encryption scheme from any CPA-secure identity-based encryption (IBE) scheme. Our construction re...

Functional Encryption with Bounded Collusions via Multi-party Computation
We construct a functional encryption scheme secure against an a-priori bounded polynomial number of collusions for the class of all polynomial-size circuits. Our constructions req...
