The once distant warnings heralding the arrival of Q-Day have been moving closer by the day, leaving banks and security providers restless as they stare at the current infrastructure that would effortlessly crumble under the quantum breeze.
While the fear of future quantum computers breaking today’ s encryption standards have been brewing for a while, Google’ s recent prediction that such systems may be here as soon as 2029 is a hard pill to swallow. On the opposite end of this dramatically shrinking timeline are vast cyberattacks drilling holes in the infrastructure, exposing financial systems, communications networks and confidential records.
It has been widely understood that attackers are harvesting today, with the aim to decrypt later – the later being, once quantum computing becomes commercially viable.
All hope however is not lost, as quantum computing is now being leveraged by financial institutions as they ready their infrastructure for the eventful Q-Day ahead.
Quantum-safe security frameworks and cryptographic migration strategies designed to withstand future quantumenabled attacks are of growing importance among top financial institutions.
