COZMO - A New Lightweight Stream Cipher [PDF]

2018 Second International Conference on Green Computing and Internet of Things (ICGCIoT), 2017
This paper deals with the merger of the two lightweight stream ciphers – A5/1 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 (output) will act as the input of the A5/1 cipher.

Speech Encryption using Fixed Point Chaos based Stream Cipher (FPC-SC) [PDF]

Engineering and Technology Journal, 2016
Fixed point chaos based stream cipher (FPC-SC) is presented in this paper to encrypt the speech signal. Fixed point chaos based pseudo random bit generator (FPC-PRBG) is used as key sequence in stream cipher system. Two chaotic Lorenz and Chen systemsare

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 ...

Hénon stream cipher

Electronics Letters, 1992
The chaotic Henon mapping has been proposed as a method of generating a binary sequence, the Henon sequence. Here it is proven that the subsequence 1100 never occurs in the Henon sequence, so the sequence is not a good key-stream. The distribution of other subsequences of length 4 is also illustrated. >

On the Role of the Inner State Size in Stream Ciphers [PDF]

, 2004
Many modern stream ciphers consist of a keystream generator and a key schedule algorithm. In fielded systems, security of the keystream generator is often based on a large inner state rather than an inherently secure design.

Numerical solvers and cryptanalysis

Journal of Mathematical Cryptology, 2009
In this paper, we present an approach to apply numerical methods in the cryptanalysis of modern cryptographic algorithms. We focus on the stream cipher Trivium. It is a stream cipher recommended by the eStream project in the hardware category.
