Graph labellings and external difference families
Gavin Angus, Sophie Huczynska, Struan McCartney
Digraph-defined external difference families were recently introduced as a natural generalization of several well-studied combinatorial objects motivated by cryptography (e.g. exte…

Digraph-defined external difference families and new circular external difference families
Sophie Huczynska, Christopher Jefferson, Struan McCartney
External difference families (EDFs) are combinatorial objects which were introduced in the early 2000s, motivated by information security applications such as the construction of A…
