Interruption Slide Attack against Stream Cipher LEX Algorithm
Chao Li · Information Security and Communications Privacy · 2007
This paper discusses the basic principle of the slide attack thought, and proposes a concept of the interrup- tion slide attack. It then analyzes the security of improved stream cipher LEX algorithm by applying the interruption slide attack. In accordance with the influences of interruption slide attack on the security of LEX, the key scheme algorithm of LEX is modified so that the slide attack and interruption slide attack against LEX is no longer of effects.
