FINANCIAL SERVICESQUANTUM RISK
Payment processing, interbank communications, and digital signatures are all at risk from quantum computers. PTG helps financial institutions prepare for the post-quantum era.
Financial Quantum Vulnerabilities
Payment Card Processing
PCI-protected cardholder data relies on RSA and ECC encryption that quantum computers will break.
Interbank Communications
SWIFT, ACH, and FedNow transactions depend on public-key cryptography for authentication and integrity.
Digital Signatures
Transaction non-repudiation relies on digital signatures that quantum computers can forge.
Online and Mobile Banking
TLS connections protecting customer sessions use key exchange algorithms vulnerable to quantum attack.
Regulatory Landscape
PCI DSS 4.0
PCI DSS requires strong cryptography. As NIST deprecates classical algorithms, PCI compliance will require PQC adoption.
FFIEC and OCC Guidance
Federal regulators are issuing guidance on cryptographic risk management that includes quantum threat considerations.
NYDFS 23 NYCRR 500
New York cybersecurity regulations require encryption risk assessments that must account for emerging threats.
SOX Compliance
Financial data integrity requirements under SOX depend on cryptographic controls that quantum computing threatens.
Frequently Asked Questions
When will quantum computers threaten financial systems?
The timeline is uncertain, but most experts estimate cryptographically relevant quantum computers by 2030 to 2035. However, harvest-now-decrypt-later attacks mean the threat to long-lived financial data is already active.
Does PCI DSS require post-quantum cryptography?
Not yet explicitly, but PCI DSS 4.0 requires strong cryptography that meets current NIST standards. As NIST transitions to PQC, PCI requirements will follow.
