How Leaky Is an Extractor?
This paper discusses the security of a leakage-resilient stream cipher presented at FOCS 2008, instantiated in a practical setting. Based on a case study, we put forward implementa...

On the (Im)Possibility of Practical and Secure Nonlinear Filters and Combiners
A vast amount of literature on stream ciphers is directed to the cryptanalysis of LFSR-based filters and combiners, resulting in various attack models such as distinguishing attac...

Provably-Secure Schemes for Basic Query Support in Outsourced Databases
In this paper, we take a closer look at the security of outsourced databases (aka Database-as-the-Service or DAS), a topic of emerging importance. DAS allows users to store sensit...

Extending the Resynchronization Attack
Abstract. Synchronous stream ciphers need perfect synchronization between sender and receiver. In practice, this is ensured by a resync mechanism. Daemen et al. [10] first describ...

On Cipher-Dependent Related-Key Attacks in the Ideal-Cipher Model
Abstract. Bellare and Kohno introduced a formal framework for the study of related-key attacks against blockciphers. They established sufficient conditions (output-unpredictabilit...
