Submission to ECRYPT call for stream ciphers: the self-synchronizing stream cipher Mosquito
In this document we specify and motivate the hardware-oriented self-synchronizing stream cipher Mosquito and the underlying cipher architecture and provide hardware implementation results. This stream cipher is a close variant of the cipher ΥΓ, described in [2]. ΥΓ in its turn was a corrected version of the cipher KNOT published in [1], removing the weaknesses that have lead to its breaking in ...
متن کاملChosen Ciphertext Attack on a New Class of Self-Synchronizing Stream Ciphers
At Indocrypt’2002, Arnault et al. proposed a new class of self-synchronizing stream ciphers combining LFSR and FCSR architectures. It was claimed to be resistant to known attacks. In this paper, we show that such a self-synchronizing stream cipher is extremely vulnerable to chosen ciphertext attack. We can restore the secret keys easily from one chosen ciphertext with little computation. For th...
متن کاملNon-Linearity and Security of Self Synchronizing Stream Ciphers
Several proposed chaos based ciphers exploit the ergodic property of chaotic orbits. As chaotic systems are unstable and have sensitive dependence on initial conditions, the main difficulty for the receiver is to reproduce the chaotic signal that has been generated by the sender in order to correctly decrypt the message. This is performed by a self synchronizing device. In discrete cryptography...

متن کاملNew Applications of T-Functions in Block Ciphers and Hash Functions
Abstract. A T-function is a mapping from n-bit words to n-bit words in which for each 0 ≤ i < n, bit i of any output word can depend only on bits 0, 1, . . . , i of any input word. All the boolean operations and most of the numeric operations in modern processors are T-functions, and all their compositions are also T-functions. Our earlier papers on the subject dealt with “crazy” T-functions wh...
