Towards Low Energy Stream Ciphers [PDF]
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.

An Analysis of the Hermes8 Stream Ciphers [PDF]
, 2007 Hermes8 [6,7] is one of the stream ciphers submitted to the ECRYPT Stream Cipher Project (eSTREAM [3]). In this paper we present an analysis of the Hermes8 stream ciphers. In particular, we show an attack on the latest version of the cipher (Hermes8F), which requires very few known keystream bytes and recovers the cipher secret key in less than a ...

Analysis of lightweight stream ciphers [PDF]
, 2008 Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell phones, RFID transponders, smart cards or devices in sensor networks. Besides efficiency, security is

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.

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

Linear Attacks on Stream Ciphers
, 2011 This paper is a survey of how linear attacks can be applied on stream ciphers. It gives an overview of the development of linear attacks and a short theoretical explanation on how a linear attack on a stream cipher is typically launched today.

One to One Identification of Cryptosystem Using Fisher’s Discriminant Analysis
International Journal of Networked and Distributed Computing (IJNDC), 2018 Distiguishing analysis is an important part of cryptanalysis. It is an important content of discriminating analysis that how to identify ciphertext is encrypted by which cryptosystems when it knows only ciphertext.
