国内初、量子暗号で金融データ送受信　東芝などが共同検証

　東芝や野村ホールディングス、総務省が所管する情報通信研究機構などは２１日、盗聴が理論上不可能とされる「量子暗号」の技術を使い金融データを送受信する共同検証を始めたと発表した。通信の安定性やデータの送信速度などを確認する。
　量子暗号は世界各国で研究が進む次世代技術。金融データを使った検証は国内で初めてとなる。東京都内の野村証券の拠点に東芝製の量子暗号装置を設置し、数キロ先の研究機構拠点との間で大容量の株式情報を送受信。１年以上をかけ、実用化に向けた課題を整理する。（2020/12/21-14:06）

Toshiba Corp. , Nomura Holdings Inc. and others said Monday they have launched a joint experiment to transmit quantum-encrypted financial data.
   The experiment, also joined by the communications ministry-linked National Institute of Information and Communications Technology, is aimed at assessing the stability, speed and other aspects of such data transmission.
   Quantum cryptography is a next-generation technology that allows theoretically unbreakable encryption. Companies and institutions across the world are racing to advance studies on the technology.
   The joint experiment became Japan's first test of transmission of financial data using quantum cryptography.
   A quantum cryptographic device, developed by Toshiba, is set up at a Nomura Holdings base in Tokyo. A large volume of stock information will be transmitted between the base and an NICT site, located several kilometers apart from each other.
