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.

Bias in the LEVIATHAN Stream Cipher [PDF]

open access: yes, 2002
We show two methods of distinguishing the LEVIATHAN stream cipher from a random stream using 236 bytes of output and proportional effort; both arise from compression within the cipher. The first models the cipher as two random functions in sequence, and shows that the probability of a collision in 64-bit output blocks is doubled as a result; the second

COZMO - A New Lightweight Stream Cipher [PDF]

open access: yes2018 Second International Conference on Green Computing and Internet of Things (ICGCIoT), 2017
This paper deals with the merger of the two lightweight stream ciphers – A5/1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks of the individual algorithms. The bits generated by the Trivium cipher (output) will act as the input of the A5/1 cipher.

NOCAS : A Nonlinear Cellular Automata Based Stream Cipher [PDF]

open access: yesDiscrete 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]

open access: yesمجلة 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

open access: yesمجلة 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

open access: yesIACR 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.
