摘要： An authentication method is provided which is capable of performing message authentication within an allowable time regardless of the magnitude of the number of messages and performing message authentication high in accuracy within a range for which the allowable time allows. Upon transmission by wireless communications with another mobile or a fixed station, a message authentication code of communication data and a digital signature are generated (S200 and S300). The generated message authentication cod and digital signature are transmitted with being added to the communication data. Upon reception, whether authentication should be done using either one of the message authentication code and the digital signature included in received information is determined according to its own state for the authentication (S400 and S500). This state includes, for example, a load state of a central processing unit or the like that performs an authentication process.

摘要： On ad hoc networks in which connection relationships among communication terminals constantly change, the processing load increases when authentication is performed each time a connection relationship changes. According to this invention, when communication terminals possess the same common key, mutual authentication is conducted with that common key, and when communication terminals do not possess the same common key, mutual authentication is conducted with a public key. Communication terminals that conducted mutual authentication exchange and retain a common key that they selected and common keys received from other communication terminals. When neither communication terminal possesses a common key at authentication, one terminal creates a common key and distributes it to the other terminal, and when one terminal has a common key it creates that common key and distributes it to the other terminal. Further, a common key possessed by a communication terminal corresponding to a relay node is broadcast periodically.

摘要： A communication system includes a certificate authority for performing authentication, a roadside device, a vehicle-mounted terminal, a first server, and a second server. The vehicle-mounted terminal transmits position information to the first server. The certificate authority acquires information about a vehicle-mounted terminal likely to appear according to place and time from the first server. The certificate authority allows the second server to verify validity of a certificate for a vehicle-mounted terminal acquired from the first server. The certificate authority generates a first list of vehicle-mounted terminals having valid certificates and a second list of vehicle-mounted terminals having invalid certificates according to place and time based on a verification result. The certificate authority transmits the first and second lists to the roadside device and the vehicle-mounted terminal. The roadside device and the vehicle-mounted terminal verify a certificate using the received first and second lists thereby reducing the certificate verification time.

摘要： In an indoor positioning system, for establishment of a cost sharing system, the positioning information transmission device does not directly transmit positional information but performs concealment and variablization on the device ID and transmits the concealed and variablized device ID. The positioning information management server stores and manages correspondence between the device IDs and positional information, and performs conversion from the device ID to the positional information in accordance with the correspondence. Further, the problem of conflict between concealed IDs upon concealment of positioning identification information by the positioning information transmission devices, which occurs when all the positioning information transmission devices use the same secret key, can be prevented. The system can be operated even when the bit length of the device ID is short.
