Self-synchronizing stream ciphers and dynamical systems: state of the art and open issues [PDF]
, 2010 International audienceDynamical systems play a central role in the design of symmetric cryptosystems. Their use has been widely investigated both in ''chaos-based'' private communications and in stream ciphers over finite fields. In the former case, they

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.

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 ...

Comparison analysis of stream cipher algorithms for digital communication [PDF]
, 2007 The broadcast nature of radio communication such as in the HF (High Frequency) spectrum exposes the transmitted information to unauthorized third parties. Confidentiality is ensured by employing cipher system.

Simulating Auxiliary Inputs, Revisited [PDF]
, 2016 For any pair $(X,Z)$ of correlated random variables we can think of $Z$ as a randomized function of $X$. Provided that $Z$ is short, one can make this function computationally efficient by allowing it to be only approximately correct.

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.

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

A fast and light stream cipher for smartphones [PDF]
, 2013 We present a stream cipher based on a chaotic dynamical system. Using a chaotic trajectory sampled under certain rules in order to avoid any attempt to reconstruct the original one, we create a binary pseudo-random keystream that can only be exactly ...

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.
