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.
摘要翻译：导航装置的CPU存储设置了优先级的公钥，并且由公钥存储部中的信息分发中心发布。导航装置的CPU提取从信息分发中心分发的分发数据的电子签名，并且按照优先级顺序仅使用公钥中的“有效”公钥来验证电子签名。导航装置的CPU确定分发数据是当电子签名通过验证时从信息分发中心分发的有效信息。

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.
