SYSTEMS AND METHODS FOR MASKING ECC OPERATIONS

Abstract:

Presented are low-cost secure systems and methods that protect cryptographic systems against attacks that seek to exploit the shortcomings of common software-based erasure mechanisms. Various embodiments, protect an Elliptic-Curve Cryptography (ECC) secret from fault attacks. This may be accomplished, for example, by not exposing ECC secrets from the Modular Arithmetic Accelerator (MAA) memory after a Destructive Reset Source (DRS).
