Vectorization on ChaCha Stream Cipher [PDF]
2014 11th International Conference on Information Technology: New Generations, 2014 This paper describes software optimization for the stream Cipher ChaCha. We leverage the wide vectorization capabilities of the new AVX2 architecture, to speed up ChaCha encryption (and decryption) on the latest x86_64 processors. In addition, we show how to apply vectorization for the future AVX512 architecture, and get further speedup.

Enhancing Embedded Data Security By Turns Cipher Block Chaining Mode Into Stream Cipher [PDF]
Engineering and Technology Journal, 2009 In this paper, a secure data hiding method is introduced. It increases the security of embedded data through combining between the steganography and cryptography. First, the secrete message is divided into blocks with same size according to length of key

IACR Transactions on Symmetric Cryptology, 2022 Stream ciphers are vulnerable to generic time-memory-data tradeoff attacks. These attacks reduce the security level to half of the cipher’s internal state size.

Algebraic Description and Simultaneous Linear Approximations of Addition in Snow 2.0. [PDF]
, 2008 In this paper we analyse the algebraic properties over the field GF(2) of the addition modulo 2pn. We look at implicit quadratic equations describing this operation, and at probabilistic conditional linear equations.

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.

The Dragon stream cipher: Design, analysis and implementation issues [PDF]
, 2008 Dragon is a word-based stream cipher. It was submitted to the eSTREAM project in 2005 and has advanced to Phase 3 of the software profile. This paper discusses the Dragon cipher from three perspectives: design, security analysis and implementation.

Cryptanalysis of RC4(n, m) stream cipher [PDF]
, 2013 RC4(n, m) is a stream cipher based on RC4 and is designed by G. Gong et al. It can be seen as a generalization of the famous RC4 stream cipher designed by Ron Rivest.

Algebraic analysis of the SSS stream cipher [PDF]
, 2011 Both the SSS and SOBER-t32 stream cipher designs use a single word-based shift register and a nonlinear filter function to produce keystream. In this paper we show that the algebraic attack method previously applied to SOBER-t32 is prevented from ...
