2月17日，
“我们已经成功地在区块链上使用量子密码通信进行了演示实验。”
经证实，“该技术用于银行间信息网络，运行正常”。
区块链上的量子密码学：
随着网络攻击威胁的增加，我们将继续努力加强我们的防御能力。
量子密码学：
也称为量子密钥分发 (QKD)。
将信息转换为密文，
将密文转换为原始信息的“密钥”是根据量子力学原理发送的。
即使出现高速计算机，理论上也无法窃听。
摩根大通：
国际汇款所需资料，
银行之间进行通信的网络“链接”，
以美元计价的数字货币“JPM coin”等
我们正在开发利用区块链的服务。
加强防御力是未来传播的问题。

摩根大通的研究机构领导了示范实验，并利用了东芝的QKD技术。
QKD网络：
由 Siena 等三家公司开发的 QKD 网络。
据说它已经证明了它能够立即检测和保护窃听者的能力。

JPMorgan Chase, Toshiba and Ciena Build the First Quantum Key Distribution Network Used to Secure Mission-Critical Blockchain Application
NEW YORK, NY; HANOVER, MD
– February 17, 2022 –In groundbreaking research,
JPMorgan Chase, Toshiba and Cienahave demonstrated the full viability of a first-of-its-kind Quantum Key Distribution (QKD) network for metropolitan areas, resistant to quantum computing attacks and capable of supporting 800 Gbps data rates for mission-critical applications under real-world environmental conditions.
The research team demonstrated
the ability of the newly developed QKD network to instantly detect and defend against eavesdroppers.It also studied the impact of realistic environmental factors
on the quality of the quantum channel and used a QKD-secured optical channel to deploy and secure Liink by J.P. Morgan,
the world’s first bank-led,
production-grade, peer-to-peer blockchain network.This is the first demonstration of
QKD securing a mission-critical blockchain application in the industry.Under the leadership of JPMorgan Chase’s Future Lab for Applied Research and Engineering (FLARE) and Global Network Infrastructure teams, researchers from all three organizations collaborated to achieve the following notable results:
A QKD channel was multiplexed on the same fiber as ultra-high bandwidth 800 Gbps optical channels for the first time and used to provide keys for encryption of the data stream.
Co-existence of the quantum channel with two 800 Gbps and eight 100 Gbps channels was demonstrated for a 70km fiber, with a key rate sufficient to support up to 258 AES-256 encrypted channels at a key refresh rate of 1 key/sec.
Operation of QKD and the ten high-bandwidth channels was demonstrated for distances up to 100km.
The proof of concept network infrastructure relied on Toshiba’s Multiplexed QKD System,
manufactured by Toshiba Europe at their Cambridge UK base, and Ciena’s Waveserver 5 platform, equipped with 800 Gbps optical-layer encryption and open APIs running over Ciena’s 6500 photonic solution.
The tests were conducted in JPMorgan Chase’s fiber optic production simulation lab.
