   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; correlation attack; irregularly clocked filter generator; distinguishing attacks; Stream ciphers; filter generator; Pomaranch; Dragon; LILI-128; LILI-II;

   Abstract : Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. READ MORE
