SECURE COMMUNICATIONS AMONGST CONNECTED DICE

Abstract:

A plurality of dice having at least a first die and a second die. The first die can generate a measure of the first die using a cryptographic algorithm, a public key and a private key, and a digital signature according to the measure and the private key. The digital signature can include a digest encrypted by the private key. The digest can include the measure. The first die can communicate the measure, the digital signature, and the public key to the second die. The second die can store a validation code representative of a measure of the first die and validate the digital signature using the public key as well validate the measure by comparing the measure to the validation code.
