After-the-Fact Leakage in Public-Key Encryption
What does it mean for an encryption scheme to be leakage-resilient? Prior formulations require that the scheme remains semantically secure even in the presence of leakage, but onl...

Circular and Leakage Resilient Public-Key Encryption under Subgroup Indistinguishability - (or: Quadratic Residuosity Strikes Ba
The main results of this work are new public-key encryption schemes that, under the quadratic residuosity (QR) assumption (or Paillier's decisional composite residuosity (DCR...

Public-Key Cryptosystems Resilient to Key Leakage
Most of the work in the analysis of cryptographic schemes is concentrated in abstract adversarial models that do not capture side-channel attacks. Such attacks exploit various for...

Public-Key Encryption in the Bounded-Retrieval Model
We construct the first public-key encryption scheme in the Bounded-Retrieval Model (BRM), providing security against various forms of adversarial “key leakage” attacks. In th...

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...
