On Software Implementation of Fast DDP-based Ciphers
Data-dependent (DD) permutations (DDP) are discussed as a cryptographic primitive for the design of fast hardware, firmware, and software encryption systems. DDP can be performed...

On Cipher Design Based on Switchable Controlled Operations
This paper concerns the problem of reducing the implementation cost of the switchable data-dependent operations (SDDOs) that are a new cryptographic primitive oriented to the desi...

Leakage-Resilient Pseudorandom Functions and Side-Channel Attacks on Feistel Networks
Abstract. A cryptographic primitive is leakage-resilient, if it remains secure even if an adversary can learn a bounded amount of arbitrary information about the computation with e...

Proofs of Security for the Unix Password Hashing Algorithm
We give the first proof of security for the full Unix password hashing algorithm (rather than of a simplified variant). Our results show that it is very good at extracting almost...

Are PCPs Inherent in Efficient Arguments?
Starting with Kilian (STOC ‘92), several works have shown how to use probabilistically checkable proofs (PCPs) and cryptographic primitives such as collision-resistant hashing to...
