Differential Cryptanalysis of Round-Reduced PRINTcipher: Computing Roots of Permutations
At CHES 2010, the new block cipher PRINTcipher was presented. In addition to using an xor round key as is common practice for round-based block ciphers, PRINTcipher also uses key-dependent permutations. While thi...

Cryptanalysis of the Light-Weight Cipher A2U2
In recent years, light-weight cryptography has received a lot of attention. Many primitives suitable for resource-restricted hardware platforms have been proposed. In this paper, we present a cryptanalysis of ...

Cryptanalysis of ARMADILLO2
ARMADILLO2 is the recommended variant of a multipurpose cryptographic primitive dedicated to hardware which has been proposed by Badel et al. in [1]. In this paper, we describe a meet-in-the-middle technique r...

Nonce Generators and the Nonce Reset Problem
A nonce is a cryptographic input value which must never repeat within a given context. Nonces are important for the security of many cryptographic building blocks, such as stream ciphers, block cipher modes of...

Concrete Security for Entity Recognition: The Jane Doe Protocol
Entity recognition does not ask whether the message is from some entity X, just whether a message is from the same entity as a previous message. This turns turns out to be very useful for low-end devices. The cur...

Improved Cryptanalysis of the Self-Shrinking Generator
We propose a new attack on the self-shrinking generator [8]. The attack is based on a backtracking algorithm and will reconstruct the key from a short sequence of known keystream bits. We give both mathematical a...
