Governments and international institutions are taking proactive measures to address the potential threat that quantum computers pose to modern encryption systems. On Friday, regulatory discussions regarding quantum risks took place at the UN Headquarters during the Government Blockchain Association’s Future of Money, Governance and the Law summit.
The urgency stems in part from a major shift by the US National Security Agency toward post-quantum cryptography. Beginning in 2027, new commercial national-security systems will be required to support quantum-resistant algorithms, with incompatible systems facing a phase-out by 2030. Security experts highlight a strategy known as “harvest now, decrypt later,” wherein attackers steal encrypted data today in anticipation of future quantum machines cracking it.
UN Pension Fund Addresses Blockchain Vulnerabilities
During a panel discussion featuring IRS Chief Risk and Control Officer Dottie Romo, UN Joint Staff Pension Fund Deputy Chief Executive Dino Cataldo Dell’Accio, and Mastercard’s Julius Moye, quantum migration emerged as a critical concern.
Dell’Accio noted that quantum migration is already a live issue for the UN pension fund’s blockchain-based proof-of-life system, which serves approximately 80,000 beneficiaries across 190 countries. Having been in production for five years, the primary concern centers on what will happen to historical information already recorded on a blockchain if current cryptography becomes vulnerable.
Consequently, the fund is actively exploring a post-quantum-resistant blockchain as well as methods to re-encrypt and publicly anchor historical records. Dell’Accio cautioned that unlike the Y2K bug, there may not be a single, definitive "Q-Day" for upgrades, noting that cryptography will demand continuous monitoring as threats evolve.
Infrastructure and Regulatory Challenges
Beyond algorithmic shifts, organizations face hardware and infrastructure hurdles. Dell’Accio pointed out that quantum-safe cryptographic keys can be significantly larger, potentially requiring upgrades to existing firewalls, network hardware, and software. Meanwhile, the National Institute of Standards and Technology (NIST) is urging organizations to migrate to finalized post-quantum standards without waiting for fully realized quantum computers.
Concluding the discussions, IRS officer Dottie Romo issued a broader warning regarding regulatory responsiveness. She stated that reviewing matters at a traditional pace is no longer sustainable as the financial sector races to protect itself against future quantum threats.
