Abstract: |
|||
| According to one embodiment, a clock generating unit configured to generate a clock having a predetermined frequency, an input value generating unit configured to generate an input value for predetermined encryption algorithm based on a generated clock, and a calculation processing unit configured to generate random number data by executing the encryption algorithm based on a generated input value are integrated, and a clock and an input value are enclosed inside the integrated circuit so as to be unobservable from the outside of the integrated circuit. | |||
