Accelerated cryptographic calculation, in particular ecc - calculation, in the processor with montgomery - said co-processor

摘要

The present invention provides a process for the accelerated performing a cryptographic calculation, in particular ecc - calculation, in a processor having a main processor (cpu) and a the main processor (cpu) associated montgomery - said co-processor. The calculation is carried out in an accelerated, in that when carrying out the calculation of at least one modular addition by a simple addition of is replaced and / or at least one modular subtraction wild replaced by a simple subtraction.
