With the increasing word size and sophisticated
optimizations of multiplication units in modern
microprocessors, it becomes increasingly likely that
they contain some undetected bugs. This was

A similar attack can be applied to any security scheme based on
discrete logs modulo a prime, and to any security scheme based on
elliptic curves (in which we can
