Encoding and Decoding of Several Optimal Rank Metric Codes

2022 · arXiv (Cornell University)

This paper presents encoding and decoding algorithms for several families of optimal rank metric codes whose codes are in restricted forms of symmetric, alternating and Hermitian matrices. First, we show the evaluation encoding is the …

Low c-differentially uniform functions via an extension of Dillon's switching method

2022 · arXiv (Cornell University)

In this paper we generalize Dillon's switching method to characterize the exact $c$-differential uniformity of functions constructed via this method. More precisely, we modify some PcN/APcN and other functions with known $c$-differential uniformity in a …
