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.

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

Using Evolving Algorithms to Cryptanalysis Nonlinear Cryptosystems
مجلة بغداد للعلوم, 2020 In this paper, new method have been investigated using evolving algorithms (EA's) to cryptanalysis one of the nonlinear stream cipher cryptosystems which depends on the Linear Feedback Shift Register (LFSR) unit by using cipher text-only attack.

Atom: A Stream Cipher with Double Key Filter
IACR Transactions on Symmetric Cryptology, 2021 It has been common knowledge that for a stream cipher to be secure against generic TMD tradeoff attacks, the size of its internal state in bits needs to be at least twice the size of the length of its secret key.
