摘要： A CPU of a navigation apparatus stores public keys to which priorities are set and which are published by an information distribution center in a public key storage section. The CPU of the navigation apparatus extracts an electronic signature of distribution data which is distributed from the information distribution center and verifies the electronic signature by using only ‘valid’ public keys among the public keys in order of the priorities. The CPU of the navigation apparatus determines that the distribution data is valid information which is distributed from the information distribution center when the electronic signature passes verification.

摘要： Map information distribution systems and methods store map information and version information for each road category of the map information stored in a navigation device, the version information correlated with identification information identifying the navigation device. The systems and methods receive the identification information from the navigation device and obtain, based on the received identification information, the version information for each road category of the map information stored in the navigation device corresponding to the stored identification information. The systems and methods extract, based on the obtained version information for each road category, differential data for each road category with stored map information of a latest version, and transmit the extracted differential data for each road category to the navigation device corresponding to the received identification information.

摘要： In a communication system for downloading programs from a center to in-vehicle terminals, a center can check whether downloading has been completed normally or a program is operating normally in an in-vehicle terminal. According to the timing of activating a downloaded program, an in-vehicle terminal checks whether the program is activated to operate normally. The information is transmitted to the center. Based on the information, the center becomes aware of the fact that downloading has been completed without any problem and that the program is operating normally in the in-vehicle terminal.
