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.

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

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

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.

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 ...

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 ...

COZMO-A New Lightweight Stream Cipher [PDF]
2018 Second International Conference on Green Computing and Internet of Things (ICGCIoT), 2018 This paper deals with the merger of the two lightweight stream ciphers: A5by1 and Trivium. The idea is to make the key stream generation more secure and to remove the attacks of the individual algorithms. The bits generated by the Trivium cipher will act as the input of the A5by1 cipher.
