报告摘要:
The differential spectrum of a function can be used to analyze its resistance against some variants of differential cryptanalysis, and also plays a significant role in sequences, coding theory and combinatorial design. A complete investigation on the differential spectrum of a given function is interesting yet challenging in general.
Our talk will introduce the research progresses in this area, including the following topics:
an overview of previously known results,
the commonly-used methods for computing the differential spectra,
new results about the differential spectra of some power mappings and some binomials with low differential uniformity,
some open problems and related research topics will also be discussed.
