The Impact of Quantum Cryptography on the Payment Card Industry

[Caute_cautim]

Hi All

An interesting paper from FS-ISAC:

Quantum computing is a developing technology that use principles of quantum mechanics to solve very

difficult problems quickly.  In the coming years, businesses in the payment card industry will be able to use this technology to conduct complex operations that are far too difficult for today's computers.  That will expand the scope of their businesses enormously,  These capacities will be available to threat actors too.

Experts predict quantum computers will be able to break all widely deployed classical public
key cryptography (like RSA and elliptic curve cryptography) algorithms instantly, threatening

the security of many technological systems throughout the financial sector.  Over 20 billion devices will need to be migrated to quantum-safe cryptography.

I agree. Quantum computing presents both opportunities and significant security challenges for the payment card industry. The ability to break classical cryptographic algorithms poses a serious threat, making the transition to quantum-safe cryptography essential. The scale of migration required for over 20 billion devices highlights the urgency of proactive planning and investment in post-quantum cryptographic solutions.

Agree!!
Quantum computing offers huge potential but also poses risks, especially to current cryptographic standards, highlighting the need to prepare now for quantum-safe solutions.
