Two Algebraic Attacks Against the F-FCSRs Using the IV Mode

This article presents some new results concerning two algebraic attacks against the F-FCSR constructions proposed in [2]. We focus on the parameters of the stream ciphers proposed that permit to mount algebraic attacks when using the IV mode. The complexity obtained for the first attack described here is 245 binary instructions using 215 known IV values for the
