Introduction
The financial services sector in Europe is being urged to prioritize the transition to quantum-safe cryptography due to the looming threat posed by quantum computing. This threat is particularly concerning in the context of “store now, decrypt later” (SNDL) attacks [2] [4] [5] [6], which involve the theft of encrypted data today with the intention of decrypting it in the future when quantum computers become capable of breaking current encryption methods.
Description
Europe’s financial services sector is urged to prioritize the transition to quantum-safe cryptography due to the increasing threat posed by quantum computing [2], particularly the risk of “store now, decrypt later” (SNDL) attacks [1] [2] [4] [5] [6]. These attacks involve the theft of encrypted data today [4], with the intention of decrypting it in the future when quantum computers are capable of compromising current encryption methods. Europol has highlighted this concern [2] [5], warning that the potential for a “cryptocalypse” looms, where widely used encryption techniques could be rendered ineffective. While the German Federal Office for Information Security (BSI) estimates a timeline of ten to 20 years for this threat [6], Europol suggests a slightly shorter timeframe of ten to 15 years [6], emphasizing that customer confidentiality and digital trust could be jeopardized within the next decade.
Experts predict that the arrival of Q-Day [1], when quantum computers can effectively break existing encryption [1], could occur as early as 2028 [1], depending on advancements in hardware [1]. Although the development of cryptographically relevant quantum computers (CRQCs) is believed to be at least a decade away, the immediate threat of SNDL attacks raises concerns about fraud, identity theft [1], and financial manipulation as stolen encrypted data becomes accessible [1]. This situation threatens to erode trust in digital banking [1], with the potential for fake or intercepted transactions to destabilize global finance [1].
The financial industry is lagging in the adoption of post-quantum cryptography (PQC) [1], leaving critical assets exposed [1]. In 2024, 64% of banks reported experiencing cyberattacks [1], with over half involving data destruction [1]. Furthermore, 86% of financial executives acknowledge their organizations’ unpreparedness for quantum security risks [1], prompting calls for immediate action to address these vulnerabilities. The Quantum Safe Financial Forum (QSFF) [2] [3] [4] [5] [6], which includes central banks and major industry players like Mastercard [3], emphasizes the need for banks and financial institutions to assess the security of their cryptographic standards [3]. The QSFF has provided key recommendations [4], including the prioritization of quantum-safe cryptography [4], enhanced coordination among stakeholders [4] [5], and improved cross-border collaboration [4]. Successful implementation of quantum-safe encryption requires collaboration among banks [6], technology providers [5] [6], policymakers [5] [6], and regulatory authorities [5] [6]. Additionally, banks may face legal and regulatory repercussions for failing to safeguard customer data against foreseeable quantum risks [1].
Europol advocates for public-private partnerships to expedite the global transition to PQC [1], emphasizing the urgency of addressing these emerging threats. The QSFF promotes a voluntary framework between regulators and the private sector to establish guidelines for quantum-safe cryptography and encourage standardization [6]. Immediate action is necessary to mitigate risks of financial loss and reputational damage in the industry [6], as the fragmented response to quantum threats is inadequate [1], given that these risks transcend national borders. The forum aligns with the goal of achieving quantum resistance by 2035 [3], advocating for proactive measures to prepare for quantum threats [3], even in the absence of immediate regulatory requirements under existing European Union laws.
Conclusion
The impending threat of quantum computing necessitates urgent action from the financial services sector to transition to quantum-safe cryptography. The potential impacts of failing to address these risks include significant financial loss, erosion of digital trust, and reputational damage [6]. Mitigating these threats requires coordinated efforts among banks, technology providers [5] [6], policymakers [5] [6], and regulatory authorities [5] [6]. The establishment of public-private partnerships and adherence to guidelines for quantum-safe cryptography are crucial steps toward achieving quantum resistance by 2035. Proactive measures today will safeguard the future integrity and security of financial systems in the face of quantum advancements.
