Signature Schemes with Bounded Leakage Resilience
A leakage-resilient cryptosystem remains secure even if arbitrary, but bounded, information about the secret key (or possibly other internal state information) is leaked to an adv...

Attacking Power Generators Using Unravelled Linearization: When Do We Output Too Much?
We look at iterated power generators si = se i−1 mod N for a random seed s0 ∈ ZN that in each iteration output a certain amount of bits. We show that heuristically an output of...

Security Bounds for the Design of Code-Based Cryptosystems
Code-based cryptography is often viewed as an interesting “Post-Quantum” alternative to the classical number theory cryptography. Unlike many other such alternatives, it has th...

A Framework for Universally Composable Non-committing Blind Signatures
A universally composable (UC) blind signature functionality requres users to commit to the message to be blindly signed. It is thereby impossible to realize in the plain model. Th...

Related-Key Cryptanalysis of the Full AES-192 and AES-256
In this paper we present two related-key attacks on the full AES. For AES-256 we show the first key recovery attack that works for all the keys and has 299.5 time and data complex...
