Stream cipher based on quasigroup string transformations in $Z_p^*$ [PDF]
arXiv, 2004 In this paper we design a stream cipher that uses the algebraic structure of the multiplicative group $\bbbz_p^*$ (where p is a big prime number used in ElGamal algorithm), by defining a quasigroup of order $p-1$ and by doing quasigroup string transformations. The cryptographical strength of the proposed stream cipher is based on the fact that breaking

Application of a MEMS-Based TRNG in a Chaotic Stream Cipher [PDF]
Sensors, 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.

Quantum stream cipher by Yuen 2000 protocol: Design and experiment by intensity modulation scheme [PDF]
, 2005 This paper shall investigate Yuen protocol, so called Y-00, which can realize a randomized stream cipher with high bit rate(Gbps) for long distance(several hundreds km). The randomized stream cipher with randomization by quantum noise based on Y-00 is called quantum stream cipher in this paper, and it may have security against known plaintext attacks ...

Fruit-80: A Secure Ultra-Lightweight Stream Cipher for Constrained Environments [PDF]
Entropy, 2018 In Fast Software Encryption (FSE) 2015, while presenting a new idea (i.e., the design of stream ciphers with the small internal state by using a secret key, not only in the initialization but also in the keystream generation), Sprout was proposed. Sprout

An immunity against correlation attack on quantum stream cipher by Yuen 2000 protocol [PDF]
arXiv, 2006 This paper presents the security analysis on the quantum stream cipher so called Yuen-2000 protocol (or $\alpha\eta$ scheme) against the fast correlation attack, the typical attack on stream ciphers. Although a very simple experimental model of the quantum stream cipher without a random mapper may be decrypted in the information theoretic sense by the ...

A Novel Image Encryption Scheme Based on Self-Synchronous Chaotic Stream Cipher and Wavelet Transform [PDF]
Entropy, 2018 In this paper, a novel image encryption scheme is proposed for the secure transmission of image data. A self-synchronous chaotic stream cipher is designed with the purpose of resisting active attack and ensures the limited error propagation of image data.

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.

Stream Cipher Using Genetic Algorithm [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2009 The research tackles newly suggested method in generating the random key used in stream cipher, by generating the key randomly using rand function and then applying randomness conditions if the produced key satisfy the conditions then its accepted key ...
