A Stream Cipher Proposal: Grain-128
A new stream cipher, Grain-128, is proposed. The design is very small in hardware and it targets environments with very limited resources in gate count, power consumption, and chip area. Grain-128…

Two Trivial Attacks on Trivium
TLDR
A state recovering attack with time complexity around c283.5 is presented and clearly shows that TRIVIUM has a very thin safety margin and that in its current form it can not be used with longer 128-bit keys, which resists all of the attacks proposed in this paper.

The Grain Family of Stream Ciphers
TLDR
A new family of stream ciphers, Grain, is proposed, based on two shift registers and a nonlinear output function, that have the additional feature that the speed can be easily increased at the expense of extra hardware.

An Improved Correlation Attack on A5/1
TLDR
A new approach to attack A5/1 is proposed that is a refinement of a previous attack by Ekdahl and Johansson and leads to a new attack with improved performance.

Cryptanalysis of Grain
TLDR
A key recovery attack against Grain, a lightweight stream cipher proposed by M. Hell, requires 243 computations and 238 keystream bits to determine the 80-bit key.

New State Recovery Attack on RC4
TLDR
A state recovery attack which accepts the keystream of a certain length, and recovers the internal state, and it is much smaller than the complexity of the best known previous attack 2779.

Plateaued Rotation Symmetric Boolean Functions on Odd Number of Variables
TLDR
The theoretically show the non existence of 9-variable, 3-resilient RSBF with nonlinearity 240 that has been posed as an open question in FSE 2004 and how one can make efficient search in the space of RSBFs is shown.

Attack the Dragon
TLDR
This paper presents two statistical distinguishers that distinguish Dragon from a random source both requiring around O(2155) words of the keystream, and shows that the cipher does not provide full security when the key of size 256 bits is used.

Encryption Performance Improvements of the Paillier Cryptosystem
TLDR
This article studies the encryption performance of the Paillier cryptosystem, a partially homomorphic cryptos system that allows to perform sums on encrypted data without having to decrypt first, and increases theryption performance by orders of magnitude compared to a naive implementation.

A new SNOW stream cipher called SNOW-V
TLDR
This paper is revising the SNOW 3G architecture to be competitive in such a pure software environment, making use of both existing acceleration instructions for the AES encryption round function as well as the ability of modern CPUs to handle large vectors of integers.
