Abstract:
This authentication system is provided with an authentication unit that transmits authentication information from a first communication device (10) to a second communication device (20) or vice versa, uses an encryption key to calculate authentication information in each of the first and second communication devices, and performs authentication processing between the first communication device and the second communication device by determining the calculation results. During the process of a series of instances of processing for authentication processing, the authentication unit performs first authentication (S107) based on part (61) of the calculation results communicated between the first and second communication devices and second authentication (S111) based on a separate part (62) of the calculation results communicated between the first and second communication devices.
