ELLIPTIC CURVE CRYPTOGRAHY WITH FRAGMENTED KEY PROCESSING AND METHODS FOR USE THEREWITH

摘要

A cryptography module includes a key store having a plurality of storage locations for storing a private key as k key fragments. One or more crypto-processing segments each operate based on corresponding ones of the k key fragments to process a message in accordance with elliptic curve digital signature algorithm (ECDSA) to produce a signed message.
