Stream Cipher Using Genetic Algorithm [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2009 The research tackles newly suggested method in generating the random key used in stream cipher, by generating the key randomly using rand function and then applying randomness conditions if the produced key satisfy the conditions then its accepted key ...

Towards Low Energy Stream Ciphers
IACR Transactions on Symmetric Cryptology, 2018 Energy optimization is an important design aspect of lightweight cryptography. Since low energy ciphers drain less battery, they are invaluable components of devices that operate on a tight energy budget such as handheld devices or RFID tags.

A Modification on Key Stream Generator for RC4 Algorithm [PDF]
Engineering and Technology Journal, 2020 Rivest Cipher 4 (RC4) is one of most common stream cipher, but it experience many problem, such as, there is little combination between the plaintext and cipher-text. For this reason RC4 Cipher is vulnerable to a number of attacks.

A Finite-Automaton Based Stream Cipher As a Quasigroup Based Cipher [PDF]
EPTCS 367, 2022, pp. 81-87, 2022 In this paper we show that a recently published finite automaton stream cipher can be considered as a quasigroup based stream cipher. Some additional properties of the discussed cipher are also given.

Proposed Hybrid Approach of Stream Cipher base on Selector of Encryption operation and Key Symmetric translate [PDF]
Engineering and Technology Journal, 2011 A stream cipher is a method of encrypting text (to produce cipher text) in which a cryptographic key and algorithm are applied to each binary digit in a data stream, one bit at a time. This method is not much used in modern cryptography.

NOCAS : A Nonlinear Cellular Automata Based Stream Cipher [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 LFSR and NFSR are the basic building blocks in almost all the state of the art stream ciphers like Trivium and Grain-128. However, a number of attacks are mounted on these type of ciphers.

COUNTER MODE DEVELOPMENT FOR BLOCK CIPHER OPERATIONS [PDF]
مجلة جامعة الانبار للعلوم الصرفة, 2012 There are two basic types of symmetric cipher: block ciphers and stream ciphers. Block ciphers operate on blocks of plaintext and ciphertext—usually of 64 bits but sometimes longer. Stream ciphers operate on streams of plaintext and ciphertext one bit or
