Comparison analysis of stream cipher algorithms for digital communication [PDF]

open access: yes, 2007
The broadcast nature of radio communication such as in the HF (High Frequency) spectrum exposes the transmitted information to unauthorized third parties. Confidentiality is ensured by employing cipher system.

WG-8: A Lightweight Stream Cipher for Resource-Constrained Smart Devices

open access: yesEAI Endorsed Transactions on Security and Safety, 2015
Lightweight cryptographic primitives are essential for securing pervasive embedded devices like RFID tags, smart cards, and wireless sensor nodes. In this paper, we present a lightweight stream cipher WG-8, which is tailored from the well-known Welch ...

Counter Mode Development for Block Cipher Operations [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2009
There are two basic types of symmetric algorithms: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer.

An algebraic attack on stream ciphers with application to nonlinear filter generators and WG-PRNG [PDF]

open access: yes, 2021
In this paper, we propose a new algebraic attack on stream ciphers. Starting from the well-known attack due to Courtois and Meier, we design an attack especially effective against nonlinear filter generators. We test it on two toy stream ciphers and we show that the level of security of one of stream ciphers submitted to the NIST competition on ...

Provable security against generic attacks on stream ciphers

open access: yesJournal of Mathematical Cryptology, 2023
Recent lightweight hardware-based stream cipher designs keep an external non-volatile internal state that is not part of the cipher’s hardware module. The purpose of these so-called small-state ciphers is to keep the size of the hardware and the power ...

BLOSTREAM: A HIGH SPEED STREAM CIPHER [PDF]

open access: yesJournal of Engineering Science and Technology, 2017
Although stream ciphers are widely utilized to encrypt sensitive data at fast speeds, security concerns have led to a shift from stream to block ciphers, judging that the current technology in stream cipher is inferior to the technology of block ciphers.

Secure Algorithms for SAKA Protocol in the GSM Network [PDF]

open access: yes, 2017
This paper deals with the security vulnerabilities of the cryptographic algorithms A3, A8, and A5 existing in the GSM network. We review these algorithms and propose new secure algorithms named NewA3, NewA8, and NewA5 algorithms with respect to the A3 ...

A fast and light stream cipher for smartphones [PDF]

open access: yes, 2013
We present a stream cipher based on a chaotic dynamical system. Using a chaotic trajectory sampled under certain rules in order to avoid any attempt to reconstruct the original one, we create a binary pseudo-random keystream that can only be exactly ...

Strike: Stream Cipher Based on Stochastic Lightning Strike Behaviour

open access: yesApplied Sciences, 2023
There is an increasing need for secure and fast encryption algorithms to support applications and communication protocols, and business models. In this paper, we present an alternative stream cipher (Strike) inspired by the stochastic behaviour of ...
