Abstract

Cryptographic products for mass applications, such as RFIDs or special ICs for the protection from plagiarism, always require that the price per unit costs are reduced as low as possible. This is achieved, for example, in that in such methods the required storage space is further reduced for system parameters to be permanently stored. Accordingly, in a method for coding and decoding the cryptographic system parameters of an elliptical curve, when storing the system parameters, storage cells are each completely occupied, and therefore no storage space is wasted.
