Invest in Quantum-Proof Communication Now Recommends Center for Quantum Technologies in Singapore’s Principal Investigator

By IQT News posted 26 Dec 2019

(BankInfoSecurity) Professor Alexander Ling, principal investigator at the Center for Quantum Technologies in Singapore stressed in a recent interview that CISOs need to begin investigating the use of quantum-proof cryptography to ensure security is maintained when extremely powerful quantum computers that can crack current encryption are implemented.
Quantum-proof keys can be deployed in current computer systems, not just quantum computers, Ling explains. And because quantum computing could become commonplace soon, companies need to promptly invest in quantum-proof encryption, he contends.
Quantum key distribution, a method for securely transmitting a secret key over distance that’s based on the laws of physics, enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages.
Ling says one of the key features of a quantum key is that it’s easy to detect if it has been intercepted by a third party.
In the interview, Ling also discusses:
*Progress made in quantum key distribution;
*Technological challenges in quantum-proof cryptography;
*How quantum keys are being deployed.
