Current encryption systems may no longer be enough to protect businesses from future quantum-powered cyberattacks, which could become a reality as early as 2029 or 2030, also known as Q-Day, cybersecurity experts warned.
Q-Day refers to the point when a sufficiently powerful quantum computer becomes capable of breaking widely used encryption standards, including Rivest-Shamir-Adleman (RSA) and Elliptic Curve Cryptography (ECC). These standards protect websites, emails and other internet-based systems.
“Q-Day refers to something called Quantum Day, which is when a cryptographically relevant quantum computer comes online and is able to break the current encryption,” Ramesh Nagarajan, head of Quantum Education at Eigensystems, told BusinessWorld during the “Y2Q Horizon: Preparing Leaders for Post-Quantum Cryptography” forum convened by the Asian Institute of Management (AIM).
Mr. Nagarajan said businesses should start preparing by identifying their cryptographic assets and determining which systems need the most protection.
