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.

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 ...

Cryptanalysis of the stream cipher BEAN [PDF]

open access: yesProceedings 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.

Hybrid Cipher System using Neural Network

open access: yesمجلة 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]

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

Turing: A Fast Stream Cipher [PDF]

open access: yes, 2003
This paper proposes the Turing stream cipher. Turing offers up to 256-bit key strength, and is designed for extremely efficient software implementation.It combines an LFSR generator based on that of SOBER [21] with a keyed mixing function reminiscent of a block cipher round. Aspects of the block mixer round have been derived from Rijndael [6], Twofish [

Side Channel Attack On Stream Ciphers: A Three-Step Approach To State/Key Recovery

open access: yesTransactions 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

A Novel Hybrid Elementary Cellular Automata and Its Application in a Stream Cipher

open access: yesApplied Sciences
The 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.

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 ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
