Quantum random number generator lock

A method for locking and unlocking a lock assembly comprising the steps of:

• A. providing a hub computer having a true random number generator (TRNG) configured to generate true random numbers that are based on quantum-level physical phenomena;
• B. providing a lock assembly that is in remote electrical communication with the hub computer and that has an onboard computer having a memory and that is in electrical communication with the hub computer, the lock assembly configured to switch from a locked mode to an unlocked mode in response to an unlock command issued by the onboard computer;
• C. generating a public key comprising a true random number with the hub computer;
• D. with the onboard computer, receiving a copy of the public key from the hub computer, storing the copy of the public key to the memory, and receiving a copy of a public key from a user device communicating with the onboard computer over a short-range wireless network;
• E. with the onboard computer, comparing the stored copy of the public key generated by the hub computer to the copy of the public key received from the user device and sending the unlock command to the lock assembly if the public keys match one another.

A method for securing a system of building doors comprising the steps of:

• A. providing a plurality of building doors, each with a lock assembly;
• B. receiving one or more public keys at a central computer, where each public key is a random number generated by a true random number generator (TRNG) based on quantum-level phenomena;
• C. storing a copy of one or more of the public keys to one of the plurality of lock assemblies;
• D. transmitting a copy of a first of the one or more public keys from the one lock assembly to a first user device;
• E. with the first user device, transmitting a public key to the one lock assembly;
• F. with the lock assembly, comparing the stored public key to the public key provided by the first user device to determine if the stored public key matches the public key provided by the first user device and, if the stored public key matches the public key provided by the first user device, switching the one lock assembly to an unlocked mode.

A lock system for securing a system of building doors, the lock system comprising:

• a true random number generator (TRNG) configured to generate true random keys that are based on quantum-level physical properties;
• a hub computer configured to receive one or more true random keys that are sent from the TRNG and further configured to transmit the true random keys to a lock assembly;
• a plurality of lock assemblies that are each configured to mount to and to secure one of said building doors, that are configured to switch from a locked mode to an unlocked mode in response to an unlock command, and that are each in remote electrical communication with the hub computer, each of the lock assemblies having an onboard computer that receives and stores to a memory true random numbers keys received from the hub computer, wherein each lock assembly is configured to transmit one or more of the true random keys stored to the memory to one or more user devices, and
• wherein each of the lock assemblies is configured to receive keys transmitted from user devices and wherein, after a key is received from one of said user devices, the onboard computer of each lock assembly is configured to compare true random keys that are stored to the memory to the received key to determine if at least one of the true random keys that are stored to the memory match the received key and, if at least one of the true random keys that are stored to the memory match the received key, to send said unlock command to switch the lock assembly to said unlocked mode.
