Patent KR-20030027724-A (KR)
Inventor: FUJITA SHINOBU
IPC: G06F7/58
Filed: 2002-09-25
Abstract: PURPOSE: A random number generating circuit is provided to compactly construct a random number generating circuit with a digital logic circuit as a small size and generate random numbers with high randomness for a cryptographic algorithm. CONSTITUTION: A random number generating circuit includes an uncertain logic circuit(10) and an equalizing circuit(20) fed by the uncertain logic circuit(10). The uncertain logic circuit(10) is a logic circuit in form of a digital circuit. Its principle is such that the output "0" or "1" is uncertain relative to a particular combination of input signals. When the logic output is uncertain, the output varies with time-to-time physical factors of component elements of the logic circuit(10). By using this physical phenomenon, it is possible to obtain a digital circuit whose output varies even with a constant input and to obtain a random sequence of digital signals "0" and "1". Since the order of digital signals "0" and "1" in the sequence obtained by this method depends on properties of component elements of the digital circuit, "unevenness" is produced in the appearance frequency of "0" and "1". Thus the equalizing circuit(20) carries out further digital processing of the digital signals to remove the unevenness and obtain digital random numbers with high randomness. Alternatively, as the feedback loop F, the equalizing circuit(20) is configured to supply the uncertain logic circuit(10) with a feedback signal based on the output date of the uncertain logic circuit(10) to remove the "unevenness" in the output data. The circuit for correcting frequencies of "0" and "1" is formed as a relatively compact logic circuit. Since the phenomenon as the source of random numbers is based on a physical phenomenon of each component element of the uncertain logic circuit(10), uncertain outputs are obtained in response to equal inputs. Therefore, the random number sequence does not exhibit a periodicity, and high-quality random numbers different from pseudo random numbers permitting estimation of random numbers are obtained.
