A HARDWARE/SOFTWARE PARALALISED IMPLEMENTATION OF ELLIPTIC CURVE DIGITAL SIGNATURE ALGORITHM

摘要

An authentication system and a method for signing data are disclosed. The system uses a hardware software partitioned approach. In its implementation the system of the invention compares favourably with performance and other parameters with a complete hardware or full software implementation. Particularly, advantageously there is a reduced gate count. Also as disclosed in the invention the system makes it difficult for hackers to attack the system using simple power analysis.
