LILI-128 is an LFSR based synchronous stream cipher with a 128-bit key. On 13 November 2000, LILI-128 was presented at the NESSIE workshop.[1] It is designed to be simple to implement in both software and hardware.

In 2007, LILI-128 was totally broken by using a notebook running MATLAB in 1.61 hours.[2]
