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.

On the Key-Uncertainty of Quantum Ciphers and the Computational Security of One-way Quantum Transmission [PDF]
, 2004 We consider the scenario where Alice wants to send a secret (classical) $n$-bit message to Bob using a classical key, and where only one-way transmission from Alice to Bob is possible.

Self-synchronizing stream ciphers and dynamical systems: state of the art and open issues [PDF]
, 2010 International audienceDynamical systems play a central role in the design of symmetric cryptosystems. Their use has been widely investigated both in ''chaos-based'' private communications and in stream ciphers over finite fields. In the former case, they

MV3: A new word based stream cipher using rapid mixing and revolving buffers [PDF]
, 2006 MV3 is a new word based stream cipher for encrypting long streams of data. A direct adaptation of a byte based cipher such as RC4 into a 32- or 64-bit word version will obviously need vast amounts of memory. This scaling issue necessitates a look for new

Finding low-weight polynomial multiples using discrete logarithm [PDF]
, 2007 Finding low-weight multiples of a binary polynomial is a difficult problem arising in the context of stream ciphers cryptanalysis. The classical algorithm to solve this problem is based on a time memory trade-off.

On the Security of Y-00 under Fast Correlation and Other Attacks on the Key [PDF]
, 2006 The potential weakness of the Y-00 direct encryption protocol when the encryption box ENC in Y-00 is not chosen properly is demonstrated in a fast correlation attack by S. Donnet et al in Phys. Lett. A 35, 6 (2006) 406-410.

Quantum Noise Randomized Ciphers
, 2006 We review the notion of a classical random cipher and its advantages. We sharpen the usual description of random ciphers to a particular mathematical characterization suggested by the salient feature responsible for their increased security.

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.

A New Type of Cipher: DICING_csb [PDF]
, 2007 In this paper, we will propose a new type of cipher named DICING_csb, which is derived from our previous stream cipher DICING. It has applied a stream of subkey and an encryption form of block ciphers, so it may be viewed as a combinative of stream ...
