fast discrete fourier spectra attacks on stream ciphers [PDF]

open access: yes, 2011
In this paper, some new results are presented on the selective discrete Fourier spectra attack introduced first as the RnjomHelleseth attack and the modifications due to Rnjom, Gong, and Helleseth.

ANALYSIS OF LIGHTWEIGHT STREAM CIPHERS [PDF]

open access: yes, 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.

Fast Algebraic Immunity of $2^m+2$ & $2^m+3$ Variables Majority Function

open access: yesIEEE Access, 2019
Boolean functions should possess high fast algebraic immunity (FAI) when it is used in stream ciphers in order to stand up to fast algebraic attacks. However, in previous research, the FAI of Boolean functions was usually calculated by computer. But, as everyone knows, it is very difficult to calculate the FAI of a given Boolean function with high ...

Use of Simple Arithmetic Operations to Construct Efficiently Implementable Boolean functions Possessing High Nonlinearity and Good Resistance to Algebraic Attacks [PDF]

open access: yes
We describe a new class of Boolean functions which provide the presently best known trade-off between low computational complexity, nonlinearity and (fast) algebraic immunity.

on the construction of cryptographically significant boolean functions using objects in projective geometry spaces [PDF]

open access: yes, 2012
Recently, several construction methods of highly nonlinear Boolean functions with relatively good algebraic properties were proposed. These approaches manage in optimizing most of the relevant cryptographic criteria, but not all of them at the same time.

Cascade Jump Controlled Sequence Generator [PDF]

open access: yes, 2005
Introduction Linear feedback shift registers (LFSR) are known to allow fast implementation and produce sequences with large period and good statistical properties (if the feedback polynomial is chosen appropriately).

Loiss: A Byte-Oriented Stream Cipher [PDF]

open access: yes, 2010
This paper presents a byte-oriented stream cipher -- Loiss, which takes a 128-bit initial key and a 128-bit initial vector as inputs, and outputs a key stream of bytes.
