ABSTRACT:
A cryptographic key split combiner includes a number of key split generators for generating cryptographic key splits from seed data, and a key split randomizer for randomizing the key splits to produce a cryptographic key. The key split generators can include a random split generator for generating random key splits, a token split generator for generating token key splits based on label data, a console split generator for generating console key splits based on maintenance data, a biometric split generator for generating biometric key splits based on biometric data, and a location split generator for generating location key splits based on location data. Label data can be read from storage, and can include user authorization data. A process for forming cryptographic keys includes randomizing or otherwise binding the splits to form the key.
