NON LINEAR FEEDBACK STREAM CIPHER [PDF]
, 2020 The main aim of this paper is to develop a new generation and innovative security software for applications. We proposed new stream cipher called NLFS. NLFS means Non-linear feedback stream cipher, which is a fast and secure stream cipher for egovernance

Cryptanalysis of the stream cipher BEAN [PDF]
Proceedings of the 4th international conference on Security of information and networks, 2011 BEAN is a recent stream cipher proposal that uses Feedback with Carry Shift Registers (FCSRs) and an output function. There is a sound motivation behind the use of FCSRs in BEAN as they provide several cryptographically interesting properties. In this paper, we show that the output function is not optimal.

Provable security against generic attacks on stream ciphers
Journal 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 ...

Security evaluation of Rakaposhi Stream Cipher [PDF]
, 2012 Rakaposhi is a synchronous stream cipher, which uses three main components: a non-linear feedback shift register (NLFSR), a dynamic linear feedback shift register (DLFSR) and a non-linear filtering function (NLF).

Hybrid Cipher System using Neural Network
مجلة بغداد للعلوم, 2008 The objective of this work is to design and implement a cryptography system that enables the sender to send message through any channel (even if this channel is insecure) and the receiver to decrypt the received message without allowing any intruder to ...

Bias in the LEVIATHAN Stream Cipher [PDF]
, 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

Weaknesses in the initialisation process of the Common Scrambling Algorithm Stream Cipher [PDF]
, 2014 The Common Scrambling Algorithm Stream Cipher (CSASC) is a shift register based stream cipher designed to encrypt digital video broadcast. CSA-SC produces a pseudo-random binary sequence that is used to mask the contents of the transmission.

Side Channel Attack On Stream Ciphers: A Three-Step Approach To State/Key Recovery
Transactions on Cryptographic Hardware and Embedded Systems, 2022 Side Channel Attack (SCA) exploits the physical information leakage (such as electromagnetic emanation) from a device that performs some cryptographic operation and poses a serious threat in the present IoT era. In the last couple of decades, there have

The Dragon stream cipher: Design, analysis and implementation issues
, 2008 Dragon is a word-based stream cipher. It was submitted to the eSTREAM project in 2005 and has advanced to Phase 3 of the software profile. This paper discusses the Dragon cipher from three perspectives: design, security analysis and implementation.

A Novel Hybrid Elementary Cellular Automata and Its Application in a Stream Cipher
Applied SciencesThe elementary cellular automata (ECAs) under the chaotic rule possess long periodicity and are widely used in pseudo-random number generators. However, their period is limited, related to the rule and the number of cells.
