Stream Ciphers are one of the most important cryptographic techniques for data security due
to its efficiency in terms of resources and speed. This study aims to provide a comprehensive …

An improvement in the security of stream cipher is achieved by introducing dynamic
polynomial switching in the Linear Feedback Shift Registers. Several researches declared …

This chapter explores basic concepts of symmetric key cryptography. The knowledge of
encryption key is implicitly or explicitly equivalent to knowing the decryption key. These …

Steganography involves concealing information by embedding data within cover media and
it can be categorized into two main domains: spatial and frequency. This paper presents two …

The escalating significance of securing data over the network has encouraged development
of secure encryption algorithms. Cryptography is a technique that assists in development of …

In this paper we will design a new key generator (KG) depends on the LFSR unit and chaotic
map. The designed KG can be used for many purposes, like cryptography and …
