WebMar 24, 2016 · You can indeed speed up a modular exponentiation by working in a different base, and this is routinely done by constrained implementations in real life (e.g. smart cards). But to make it work, the base has to be a power of $2$.

WebVariants of the definition In mathematics, the result of the modulo operation is an equivalence class, and any member of the class may be chosen as representative ; however, the usual representative is the least positive residue, the smallest non-negative integer that belongs to that class (i.e., the remainder of the Euclidean division). However, …
