A new distinguisher for clock controlled stream ciphers

Englund, Håkan LU and Johansson, Thomas LU (2005) In Lecture Notes in Computer Science 3557. p.181-195
Abstract
In this paper we present a distinguisher targeting towards irregularly clocked filter generators. The attack is applied on the irregularly. clocked stream cipher called LILI-II. LILI-II is the successor of the cipher LILI-128 and its design was published in [1]. There have been no known attacks better than exhaustive key search on LILI-II. Our attack is-the first of this kind that distinguishes the cipher output from a random source using 2(103) bits of keystream using computational complexity of approximately 2(103) operations.
