Cryptography module for use with fragmented key and methods for use therewith

摘要

A cryptography module includes a key store having a plurality of storage locations for storing a key as k key fragments including a plurality of random key fragments and a remainder key fragment. One or more crypto-processing segments each operate based on corresponding ones of the k key fragments to process an input signal to produce an output signal.

1. A cryptography module comprising:
a key store having a plurality of storage locations for storing a key as k key fragments in different locations of an executable file, the k key fragments including a plurality of random key fragments generated as random numbers and a remainder key fragment generated based on the plurality of random key fragments and the key; and at least one crypto-processing segment, coupled to the key store, that operates based on the execution of the executable file that uses the k key fragments to process an input signal into an output signal such that the key is never assembled.
