System and method of verification, authentication, and/or certification using entangled photons

A method of certifying a credential, the method comprising:

• a) generating a first shared secret random number by measuring one of a first pair of entangled photons using a first device and by measuring another of the first pair of entangled photons using a second device;
• b) dividing the first shared secret random number into a first cryptographic (crypto) key and a first nonce;
• c) associating the first nonce with the credential;
• d) storing the first crypto key, the first nonce, and the credential in the first device;
• e) storing the first crypto key, the first nonce, and the credential in the second device;
• f) generating a second shared secret random number by measuring one of a second pair of entangled photons using the first device and by measuring another of the second pair of entangled photons using a third device;
• g) dividing the second shared secret random number into a second crypto key and a second nonce;
• h) encrypting the first crypto key, the first nonce, and the credential with a second crypto key at the first device, and sending the encrypted first crypto key, first nonce, and credential from the first device to the third device;
• i) decrypting the sent encrypted first crypto key, first nonce, and credential at the third device using the second crypto key;
• j) sending from the third device to the second device, the first nonce from the decrypted sent encrypted first crypto key, first nonce, and credential;
• k) determining at the second device if the first nonce sent by the third device matches the first nonce stored in the second device;
• l) Encrypting at the second device, the credential stored in the second device, wherein the encryption is performed using the first crypto key, and sending the encrypted credential to the third device if the first nonce received from the third device is determined to match the first nonce stored in the second device;
• m) decrypting the encrypted credential sent by the second device at the third device;
• and
• n) determining at the third device if the decrypted encrypted credential sent by the first device matches the decrypted encrypted credential sent by the second device and certifying the credential if a match is determined.

A method of certifying a credential, the method comprising:

• a) generating a first and a second shared secret random number by performing matching processes on a first and on a second event list that contain correlated quantum state values;
• b) dividing the first shared secret random number into a first cryptographic (crypto) key and a first nonce;
• c) associating the first nonce with the credential;
• d) dividing the second shared secret random number into a second crypto key and a second nonce;
• e) encrypting the first crypto key, the first nonce, and the credential with the second crypto key;
• f) decrypting the sent encrypted first crypto key, first nonce, and credential using the second crypto key;
• g) determining if the first nonce matches the second nonce;
• and
• h) certifying the credential if the first nonce matches the second nonce.
