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.

摘要： An authentication system includes an authentication unit that performs an authentication process between a first communication device and a second communication device when the first communication device and the second communication device communicate. The authentication unit performs the authentication process by transmitting authentication information from one of the first communication device and the second communication device to the other one, calculating the authentication information with an encryption code in each of the first communication device and the second communication device, and evaluating a calculation result. During a processing series in the authentication process, the authentication unit performs a first authentication based on part of the calculation result transmitted between the first and second communication device, and a second authentication based on another part of the calculation result transmitted between the first and second communication device.

摘要： A communication device controls a process for determining a position of another device in accordance with a radio propagation environment. The communication device includes a wireless communication section configured to receive wireless signals from another communication device and a control section configured to calculate a reliability parameter. The reliability parameter serves as an indicator that indicates whether a first incoming wave serving as a signal detected as a signal that meets a predetermined detection standard is an appropriate process target, among the wireless signals received by the wireless communication section. The reliability parameter also controls a positional parameter determination process of determining a positional parameter indicating a position of the other communication device on a basis of the first incoming wave, and on a basis of the reliability parameter.
