The algorithms such as RSA, ElGamal and ECC work on integers. Commutative operations
on integer multiplication leave these algorithms vulnerable to attack by eavesdroppers. For …

In this paper, we propose public key cryptography using recursive block matrices involving
generalized Fibonacci numbers over a finite field Zp. For this, we define multinacci block …

A sure way of providing privacy to sensitive images is to encrypt them, especially when they
are stored in a public cloud server. Homomorphic encryption enables arithmetic operations …

This work includes research findings on encryption, decryption, and various image
processing operations using programmable operations, on Matlab, Simulink, and the Xilinx …

In the quest for robust and efficient digital communication, this paper introduces cutting-edge
key exchange protocols leveraging the computational prowess of tropical semirings and the …

In this research, we modify the cryptosystem from a ring over an integer to an integer modulo
m. In the previous research, the researcher used a singular matrix over integers so that the …

In this paper, we present a new encryption scheme using generalization k-Fibonacci-like
sequence, we code the points of an elliptic curve with the terms of a sequence of k-Fibonacci …

To implement hardware operations on various Xilinx FPGAs, we provide a method of
software simulation, providing models (set of Simulink blocks) and presenting the concept of …

In this paper, we have proposed a Public Key Cryptography (PKC) using block matrices with
generalized Fibonacci sequence. First, we have shown the multiplicative commutativity of …
