Fruit-80: A Secure Ultra-Lightweight Stream Cipher for Constrained Environments. [PDF]
Entropy (Basel), 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

A Novel Image Encryption Scheme Based on Self-Synchronous Chaotic Stream Cipher and Wavelet Transform. [PDF]
Entropy (Basel), 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.

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 ...

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

Stream cipher based on quasigroup string transformations in $Z_p^*$
, 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 ...

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.

DeepKeyGen: A Deep Learning-Based Stream Cipher Generator for Medical Image Encryption and Decryption [PDF]
IEEE Transactions on Neural Networks and Learning Systems, 2020 The need for medical image encryption is increasingly pronounced, for example, to safeguard the privacy of the patients’ medical imaging data. In this article, a novel deep learning-based key generation network (DeepKeyGen) is proposed as a stream cipher
