New constructions of $2$ -to- $1$ mappings over $\gf_{2^n}$ and their applications to binary linear codes

Yaqin Li, Kangquan Li, Qiancheng Zhang

The $2$ -to- $1$ mapping over finite fields has a wide range of applications, including combinatorial mathematics and coding theory. Thus, constructions of $2$ -to- $1$ mappings have a…

Balanced Boolean functions with few-valued Walsh spectra parameterized by $P (x^{2} + x)$

Qiancheng Zhang, Kangquan Li, Longjiang Qu

Boolean functions with few-valued spectra have wide applications in cryptography, coding theory, sequence designs, etc. In this paper, we further study the parametric construction…
