keys used to encrypt plaintext messages and decrypt ciphertext
communications. A cryptographic key split combiner includes a
plurality of key split generators for generating cryptographic
key splits and a key split randomizer for randomizing the
cryptographic key splits to produce a cryptographic key. Each of
the key split generators generates key splits from the seed data.
Representative independent claim 35 is reproduced as
follows:
35. A process for forming cryptographic keys, comprising:
a) generating a plurality of cryptographic key splits from
seed data; and
b) randomizing the cryptographic key splits to produce a
cryptographic key.
