Most presently used such ciphers are based on a block cipher (e g DES) in 1-bit cipher feedback mode In this paper several alternative design approaches for SSSCs are proposed that are superior to the design based on a block cipher with respect to encryption speed and potentially also with respect to security A method for combining several SSSCs is presented that allows to prove that the

06/10/2009The purpose of this article is to illustrate the potential interest of the control theory framework for cryptographic applications It is shown that under the properties of left invertibility and flatness dynamical systems are structurally equivalent to some specific cryptographic primitives called self-synchronising stream ciphers

Stream ciphers work on single bits or single words and need to maintain an internal state to change the cipher at each step Typically stream ciphers can reach higher speeds than block ciphers but their theory is less developed This is why stream ciphers are often skipped in books on cryptography This does not reflect the real importance of stream ciphers They are used in several everyday

In cryptography a stream cipher is a symmetric key cipher where plaintext bits are combined with a pseudorandom cipher bit stream (keystream) typically by an exclusive-or (xor) operation In a stream cipher the plaintext digits are encrypted one at a time and the transformation of successive digits varies during the encryption An alternative name is

In cryptography MOSQUITO was a stream cypher algorithm designed by Joan Daemen and Paris Kitsos It was submitted to the eSTREAM Project of the eCRYPT network After the initial design was broken by Joux and Muller a tweaked version named MOUSTIQUE was proposed which made it to Phase 3 of the eSTREAM evaluation process as the only self-synchronizing cipher remaining

A stream cipher makes use of a much smaller and more convenient cryptographic key for example 128 bits keys Based on this key Self-synchronizing stream ciphers is another technique that uses part of the previous N ciphertext digits to compute the keystream Such schemes are known also as asynchronous stream ciphers or ciphertext autokey (CTAK) The idea of self-synchronization was

The self-synchronizing stream cipher Moustique Moustique internal state has 8 stage registers denoted by ai including the CCSR: • a0 is the CCSR and has a length of 128 • a1 to a5 have length 53 • a6 has length 12 • a7 has length 3 The bits of the Mouches Moustiques Si le joueur attrape un moustique par erreur (ils ressemblent trs fort aux mouches) il perd l'ensemble des
