eventually uncover the structure hidden inside the S-box used by the latest Russian standards, namely the hash function Streebog and the block cipher Kuznyechik. As I will show, the presence of this structure [...] problem has three major phases: the frictional torque compresses the compliant surface until the rod stops sliding, then the rod sticks, before finally leaving the surface. The rigid body problem has one [...] replace the governing partial differential equations of the continuum mechanical model with a non-local, integral, peridynamic model. The control variables still enter the problem as coefficients of the governing
