''Cryptography - quantum computing.''

(PQC).

Cryptography is the theory and practice of encrypting information to ensure its confidentiality and security.

Post-quantum cryptography means future improved cryptography designed to be secure against attacks using quantum computing.

Post-quantum cryptography is also known as quantum-resistant cryptography.

(Although some commentators also speak and write about "quantum proof" and "quantum safe", such names may overstate the degree of safety that can be achieved.)

:"Quantum computers represent a serious threat for the financial system. If they become
practicable, they could be used to compromise the security of the current mainstream cryptographic protocols upon which the financial system relies to secure data
and transactions.

:In the mid-1990s, researchers created quantum algorithms that – at least in theory and given a sufficiently powerful quantum computer – could break today’s widely used public key cryptographic schemes.

:This would instantly render obsolete many current cryptographic techniques, threatening the foundations of our financial services infrastructure and severely impacting financial stability.

:While functional quantum computers are not yet available, the security threat needs to be
urgently addressed.

:Already, malicious actors can intercept and store confidential, classically encrypted data with the intention of decrypting it later when quantum machines become powerful enough to do so.

:This means that data stored or transmitted today are, in fact, exposed to “harvest now, decrypt later” attacks by a future quantum computer.

:The long-term sensitivity of financial data means that the potential future existence of a
quantum computer effectively renders today’s systems insecure.
