Summary:A device for generating a digital random encryption key includes an input unit adding a non-volatile active element for overcoming a limit of a passive element when generating an encryption key, applying a random passive filter, and inputting an analog voltage signal to an encryption key generator, an encryption key generator including a non-volatile active element and a passive filter, connected to the input unit through a connection substrate, and generating a random encryption key from an entropy source, and a converter for converting a signal generated by the encryption key generator into a digital signal and outputting the digital signal is provided, thereby improving robustness of security compared to the case of applying the general passive element, allowing regeneration or random generation, and generating an excellent encryption key working excellently for physical reverse engineering violations.
