翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Basic access control ： ウィキペディア英語版 Basic access control Basic access control (BAC) is a mechanism specified to ensure only authorized parties can wirelessly read personal information from passports with an RFID chip. It uses data such as the passport number, date of birth and expiration date to negotiate a session key. This key can then be used to encrypt the communication between the passports chip and a reading device. This mechanism is intended to ensure that the owner of a passport can decide who can read the electronic contents of the passport. This mechanism was first introduced into the German passport on 1 November 2005 and is now also used in many other countries (e.g., United States passports since August 2007).〔()〕 == Inner workings == The data used to encrypt the BAC communication can be read electronically from the bottom of the passport called the machine readable zone. Because physical access to the passport is assumed to be needed to know this part of the passport it is assumed that the owner of the passport has given permission to read the passport. Equipment for optically scanning this part of the passport is already widely used. It uses an OCR system to read the text which is printed in a standardized format. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Basic access control」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
