摘要： A communication device controls wireless communications dependent on radio propagation environments. The communication device includes a wireless communication section configured to receive wireless signals from another communication device, and a control section configured to control a repetition process of repeatedly executing a measurement process on a basis of a reliability parameter calculated through the measurement process. The measurement process includes reception of the wireless signals and calculation of the reliability parameter serving as an indicator that indicates whether a first incoming wave is an appropriate process target, the first incoming wave being a signal detected as a signal that meets a predetermined detection standard among the received wireless signals, wherein the reliability parameter includes a third reliability parameter serving as an indicator that indicates unsuitability of a combined wave for the first incoming wave.

摘要： An authentication system includes a first controller that performs wireless communication with a mobile terminal and a first authentication unit that executes authentication of the mobile terminal including ID authentication and code authentication through the wireless communication performed between the first controller and the mobile terminal. The first authentication unit executes the code authentication by determining whether a terminal-side calculation result obtained by the mobile terminal matches a controller-side calculation result obtained by the first controller. The authentication system further includes a second controller that communicates with the mobile terminal and a second authentication unit that applies encryption communication using a portion of the terminal-side calculation result and a portion of the controller-side calculation result to communication performed between the second controller and the mobile terminal and authenticates the encryption communication.
