The concept of lightweight cryptography has gained in popularity recently, also due to various competitions and standardization efforts specifically targeting more efficient algorithms, which are also easier to implement.
One of the important …
Keyed and unkeyed cryptographic permutations often iterate simple round functions. Substitution-permutation networks (SPNs) are an approach that is popular since the mid 1990s. One of the new directions in the design of these round functions is to …
