Improving fast algebraic attacks
Witryna197 for the attack in [11]. Moreover, unlike this previous attack, ours does not need generic Gr obner basis algorithms since it only requires to solve a linear system. This … WitrynaRecently, new kinds of attacks drawn from an original idea of Shannon [15] has emerged; these attacks are called algebraic attacks and fast algebraic attacks [6, 12]. They proceed by modelling the problem of recovering the secret key by means of an over-defined system of multivariate nonlinear equa-tions of algebraic degree at …
