On Construction of Hadamard Matrices
Shipra Kumari, Hrishikesh Mahato
In this article, a series of Hadamard matrix has been developed using some block matrices with the help of skew Hadamard matrix. Basically an internal structure of skew Hadamard ma…
On Construction of weighted orthogonal matrices over finite field and its application in cryptography
Shipra Kumari, Hrishikesh Mahato, Sumant Pushp
In this article, we propose a method to construct self orthogonal matrix, orthogonal matrix and anti orthogonal matrix over the finite field. Orthogonal matrices has numerous appli…
Encryption based on Conference Matrix
Shipra Kumari, Hrishikesh Mahato
In this article, an encryption scheme based on (-1, 1) conference matrix has been developed. The decryption key comprising of fixed number of positive integers with prime power yie…
Extension of Paley Construction for Hadamard Matrix
Shipra Kumari, Hrishikesh Mahato
We have extended the Paley constructions for Hadamard matrices and obtained some series of Hadamard matrices. Especially Paley construction-II is applicable for odd prime power q i…
