摘要： A base station authentication method which allows base station authentication to be performed by more wireless terminal apparatuses within a fixed period of time. This method is a base station authentication method for TDMA wireless communication and comprises: a step in which wireless terminal apparatuses (300) select timeslots (S2200) and use the selected timeslots to transmit, to a wireless base station apparatus (200), responses indicating the start of base station authentication (S2300); a step in which the wireless base station apparatus (200) generates base station authentication data summarizing information indicating whether there has been a response for each timeslot, for the plurality of timeslots (S2400), and transmits the generated base station authentication data to the wireless terminal apparatuses (300) (S2500); and a step in which the wireless terminal apparatuses (300) perform base station authentication on the transmission origin of the base station authentication data, based on whether the received base station authentication data indicates that there were responses at the selected timeslots (S2700).

摘要： Provided is a biometric authentication system capable of preventing spoofing attacks even if leakage of key information and a registration conversion template occurs. A communication terminal device (300) calculates secret key information k' which is exclusive OR of key information k of the registration biological information and masked value c' which is randomly selected from a predetermined error correction code group, and calculates verified information c"' which is exclusive OR of sent information c" and value c'. A biometric authentication device (500) calculates exclusive OR of authentication biological information, information k', and registration conversion template w, as information c", wherein the template w is exclusive OR of information x, information k, and authentication parameter c randomly selected from the code group; and performs biometric authentication on the basis of a degree of matching between information c"' corresponding to information c", and the parameter c.
