Construction of codes over a commutative non-unital ring from simplicial complexes and their applications

Vidya Sagar, Shikha Patel, Sanjay Kumar Singh

In this article, we investigate the construction of linear codes over a finite ring $S$ , where $S$ is taken to be an extension of a commutative non-unital ring…

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…

Subfield codes of $C_{D}$ -codes over $F_{2} [x] / ⟨ x^{3} - x ⟩$ are really nice!

Anuj Kumar Bhagat, Ritumoni Sarma, Vidya Sagar

A non-zero $F$ -linear map from a finite-dimensional commutative $F$ -algebra to $F$ is called an $F$ -valued trace if its kernel does not contain…

Minimal and Optimal binary codes obtained using $C_{D}$ -construction over the non-unital ring $I$

Vidya Sagar, Ritumoni Sarma

In this article, we construct linear codes over the commutative non-unital ring $I$ of size four. We obtain their Lee-weight distributions and study their binary Gray images. Under…

Codes over the non-unital non-commutative ring $E$ using simplicial complexes

Vidya Sagar, Ritumoni Sarma

There are exactly two non-commutative rings of size $4$ , namely, $E = ⟨ a, b ∣ 2 a = 2 b = 0, a^{2} = a, b^{2} = b, ab = a, ba = b ⟩$ and its opposite ring $F$ . These ri…

Certain binary minimal codes constructed using simplicial complexes

Vidya Sagar, Ritumoni Sarma

In this manuscript, we work over the non-chain ring $R = F_{2} [u] / ⟨ u^{3} - u ⟩$ . Let $m \in N$ and let $L, M, N \subseteq [m]:=\{1, 2, \dots, m\…

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 $…
