Cold storage cryptographic authentication apparatus and system
A secure cryptographic cold storage apparatus and system. Embodiments of the present disclosure provide for a cold storage apparatus configured to generate a private key, compute an associated PK/PKY and display the latter on a visual display screen. An associated interface apparatus is configured to retrieve the PK/PKH optically and store it in memory. The interface apparatus is configured to produce an associated message and render it at a visual display. The cold storage apparatus may retrieve the message optically, and cryptographically sign the message utilizing one or more public key cryptography methods. The cold storage apparatus produces a graphical output comprising the signed message and renders it at the visual display. The interface apparatus retrieves the signed message and verifies that the cold storage apparatus signed the message, utilizing the public key cryptography methods.
1. A cold storage system comprising:
a cold storage apparatus comprising a first computing module, a first non-transitory memory device, a first input/output interface and a first camera; and
an interface apparatus comprising a second computing module, a second non-transitory memory device, a second input/output interface and a second camera,
wherein the cold storage apparatus is operably configured to generate a cryptographic public-private keypair and display a public key or a public key hash associated with the public-private keypair,
wherein the interface apparatus is operably configured to receive the public key or the public key hash, store the public key or the public key hash in the second non-transitory memory device and process the public key or the public key hash via the second computing module to operably pair the interface apparatus with the cold storage apparatus,
wherein the interface apparatus is operably configured to generate a cryptographic message comprising the public key or the public key hash and generate a visual display of the cryptographic message at the second input/output interface,
wherein the cold storage apparatus is operably configured to scan the cryptographic message with the first camera,
wherein the cold storage apparatus is operably configured to process the cryptographic message with the first computing module and cryptographically sign the cryptographic message,
wherein the interface apparatus is operably configured to scan the cryptographically signed message with the second camera and process the cryptographically signed message with the second computing module to authenticate the cryptographically signed message.
