A group of Japanese companies said on Monday they had launched the country’s first study on quantum cryptography in a bid to improve the security of equity trading.
The joint study, initiated on the same day by Toshiba Corp., NEC Corp. and Nomura Holdings Inc., among others, comes amid growing threats of cyberattacks against financial institutions.
Quantum cryptography, in theory, is considered impossible for third parties to crack, the group said. The companies hope to put the technology to use in stock trading within several years.
In the joint investigation, they will connect a Toshiba-developed cryptographic device to a trading system at Nomura Securities Co., Nomura Holdings’ brokerage unit, and conduct a crypto test using virtual customer details and trading data.
The simulations, conducted with the help of the National Institute of Information and Communications Technology, will examine the ability to encrypt numerous orders without delay even when millions are generated simultaneously, they said. It will also check if there is any impact on the system when operations go on for days.
