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.

Nonlinear Equivalence of Stream Ciphers [PDF]
, 2010 In this paper we investigate nonlinear equivalence of stream ciphers over a finite field, exemplified by the pure LFSR-based filter generator over F2. We define a nonlinear equivalence class consisting of filter generators of length n that generate a binary keystream of period dividing 2n-1, and investigate certain cryptographic properties of the ...

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.

Secure Algorithms for SAKA Protocol in the GSM Network [PDF]
, 2017 This paper deals with the security vulnerabilities of the cryptographic algorithms A3, A8, and A5 existing in the GSM network. We review these algorithms and propose new secure algorithms named NewA3, NewA8, and NewA5 algorithms with respect to the A3 ...

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 ...

Application of a MEMS-based TRNG in a chaotic stream cipher [PDF]
, 2017 In this work, we used a sensor-based True Random Number Generator in order to generate keys for a stream cipher based on a recently published hybrid algorithm mixing Skew Tent Map and a Linear Feedback Shift Register.

Cryptanalysis of a family of self-synchronizing chaotic stream ciphers [PDF]
, 2009 Unimodal maps have been broadly used as a base of new encryption strategies. Recently, a stream cipher has been proposed in the literature, whose keystream is basically a symbolic sequence of the (one-parameter) logistic map or of the tent map.

IEICE ESS Fundamentals Review, 2009 ストリーム暗号は高速処理に優れた暗号のクラスであり，近年の情報の大規模化・通信の高速化に伴い注目を集めている．このストリーム暗号の次世代を選定するプロジェクトeSTREAM（the ECRYPT stream cipher project）が欧州にて3年間にわたり開催され，その結果として先日七つのポートフォリオが選定された．本稿では，ストリーム暗号を概観し，特にこのeSTREAMでの成果を踏まえて，現状最も使用されているストリーム暗号であるRC4，これからのストリーム暗号であるeSTREAM暗号，そして現在ISO（International Organization for Standardization）に提案されている三つの暗号の動向について解説する．

Rethinking the Weakness of Stream Ciphers and Its Application to Encrypted Malware Detection [PDF]
, 2020 Encryption key use is a critical component to the security of a stream cipher: because many implementations simply consist of a key scheduling algorithm and logical exclusive or (XOR), an attacker can completely break the cipher by XORing two ciphertexts
