  • Patent number: 12170729
    Abstract: A method and a system of providing a quantum random number based on a quantum entropy source. The method includes generating a quantum random number and providing the quantum random number to a device. The generating of the quantum random number based on the quantum entropy source includes determining, by a management unit, whether quantum random numbers stored in a storage are insufficient; generating a quantum random number based on the quantum entropy source using a quantum random number generator provided in a production unit in response to a determination that the quantum random numbers are insufficient; verifying, by a verification unit, the generated quantum random number based on NIST SP800-90B and SP800-22; and in response to quality of the generated quantum number satisfying a criterion, storing the verified quantum random number in the storage.

  • Patent number: 12118071
    Abstract: A pattern authentication method for preventing a smudge and a shoulder surfing attack. The pattern authentication method includes: a pattern registration step; and a pattern authentication step, in which the pattern registration step includes: a step of receiving a pattern from a user by an input unit of a pattern authentication device; a step of matching and storing a code value corresponding to the pattern input from the user by a matching unit; and a step of generating a user KDI (Key Derivation ID) by matching the code value to a quantum random number generated by a quantum random number generator by a KDI generator.

  • Patent number: 12058247
    Abstract: A method of providing a secure communication service using a secure communication device equipped with a quantum-random-number-based encryption chip. The method includes: in response to a first user terminal executing a secure communication device service app for secure communication and inputting a personal information number (PIN) or pattern, performing device authentication between a first user secure communication device and the first user terminal and then performing remote authentication between the first user terminal and a management server; in response to user authentication being completed, generating a quantum secret key a by a quantum encryption chip of the first user secure communication device and transmitting a quantum public key A to a second user secure communication device; and creating, by the first user secure communication device, a speech secure communication channel for communication with the second user secure communication device by inducing and storing the quantum encryption key.
