Two general attacks that can be applied to all versions and variants of the Pomaranch stream cipher are presented. The attacks are demonstrated on all versions and succeed with com...
The stream ciphers Py, Py6 designed by Biham and Seberry were promising candidates in the ECRYPT-eSTREAM project because of their impressive speed. Since their publication in Apri...
This article presents some new results concerning two algebraic attacks against the F-FCSR constructions proposed in [2]. We focus on the parameters of the stream ciphers proposed ...
Abstract. In this paper we propose a new key recovery attack on irregular clocked keystream generators where the stream is filtered by a nonlinear Boolean function. We show that t...
1 Dragon is a word oriented stream cipher submitted to the ECRYPT project, it operates on key sizes of 128 and 256 bits. The original idea of the design is to use a nonlinear feedb...
