摘要：
An integrated security device, including: an encryption/decoding processing unit for executing processing necessary for authentication by using a logic circuit that forms an encryption/decoding function; a selector for selecting signals whose number corresponds to a specific number of lines from among signals from a plurality of intermediate nodes of the logic circuit in accordance with a selection signal; and a signal processing unit having a function of detecting a glitch caused by the signals corresponding to the specific number of lines, for implementing both a function of generating a physical random number and a function of generating a device identifier by a physical characteristic based on the glitch detected by switch-selecting the signals corresponding to the specific number of lines.
