Decoding Algorithms for Two-dimensional Constacyclic Codes over $F_{q}$

Vidya Sagar, Shikha Patel, Shayan Srinivasa Garani

We derive the spectral domain properties of two-dimensional (2-D) $(λ_{1}, λ_{2})$ -constacyclic codes over $F_{q}$ using the 2-D finite field Fourier transform (FFFT). Based on…

On the Structure of Two-Dimensional Constacyclic Codes using Common Zero Sets

Vidya Sagar, Shikha Patel, Ashutosh Singh +1

We consider two-dimensional $(λ_{1}, λ_{2})$ -constacyclic codes over $F_{q}$ of area $M N$ , where $q$ is some power of prime $p$ with $g cd (M, p) = 1$ and $g cd (N, p) = 1$ . With the…

Multisecret-sharing scheme with two-level security and its applications in Blockchain

R. K. Sharma, Ritumoni Sarma, Neha Arora +1

A $(t, m)$ -threshold secret sharing and multisecret-sharing scheme based on Shamir's SSS are introduced with two-level security using a one-way function. Besides we give its applica…

Linear codes using simplicial complexes

Vidya Sagar, Ritumoni Sarma

Certain simplicial complexes are used to construct a subset $D$ of $F_{2^{n}}^{m}$ and $D$ , in turn, defines the linear code $C_{D}$ over $F_{2^{n}}$ that consists of $…
