Sound Hashing Modes of Arbitrary Functions, Permutations, and Block Ciphers
IACR Transactions on Symmetric Cryptology, 2018 Cryptographic hashing modes come in many flavors, including Merkle-Damgård with various types of strengthening, Merkle trees, and sponge functions. As underlying primitives, these functions use arbitrary functions, permutations, or block ciphers. In this

IACR Transactions on Symmetric Cryptology, 2018 We present column parity mixers (CPM), a generalization of the Θ mixing layer that is used in Keccak. Thanks to our description using matrix arithmetic, we can easily derive algebraic, diffusion, and mask propagation properties, leading to a surprising ...

A novel single-crystal & single-pass source for polarisation- and colour-entangled photon pairs
Scientific Reports, 2017 We demonstrate a new generation mechanism for polarisation- and colour-entangled photon pairs. In our approach we tailor the phase-matching of a periodically poled KTP crystal such that two downconversion processes take place simultaneously.

Under false flag: using technical artifacts for cyber attack attribution
Cybersecurity, 2020 The attribution of cyber attacks is often neglected. The consensus still is that little can be done to prosecute the perpetrators – and unfortunately, this might be right in many cases. What is however only of limited interest for the private industry is
