1. A computer processing system comprising:
an isogeny-based cryptosystem utilized with an electronic computing device that is operably configured to perform a sequence of isogeny computations and use a random input to randomize and change an intermediate elliptic curve point within the sequence of isogeny computations to a new projective coordinate representation.
