Sharing Decryption in the Context of Voting or Lotteries
Abstract. Several public key cryptosystems with additional homomorphic properties have been proposed so far. They allow to perform computation with encrypted data without the knowl...

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...

On the Insecurity of Parallel Repetition for Leakage Resilience
A fundamental question in leakage-resilient cryptography is: can leakage resilience always be amplified by parallel repetition? It is natural to expect that if we have a leakage-r...

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...

3-Move Undeniable Signature Scheme
In undeniable signature schemes, zero-knowledgeness and non-transferability have been identified so far. In this paper, by separating these two notions, we show the first 3-move ...
