Some new results on cube attacks against Trivium

Trivium is a bit oriented synchronous stream cipher designed by Cannière and Preneel. It is one of the eSTREAM hardware-oriented finalists and an International Standard under ISO/IEC 29192-3:2012. Cube attacks are an important type of key recovery attack against Trivium. First, I will give a survey on cube attacks against Trivium. Second, I will present our recent results including an algebraic method for recovering superpolies and observations that some best key recovery attacks given by division property based cube attacks are distinguishing attacks. lien: rien
