HSBC Deploys Cybersecurity Tech to Secure Digital Gold
Cybersecurity threats to the financial sector are evolving at an unprecedented pace, with quantum computing emerging as a significant concern.
The fintech industry's adoption of blockchain and distributed ledger technologies (DLT) has enhanced transparency and efficiency, but also exposed new vulnerabilities.
Quantum computers, with their ability to break current encryption algorithms, pose a particular threat to digital assets and financial transactions.
In response, HSBC, a global banking and financial services leader, has partnered with Quantinuum, a quantum computing specialist, to pioneer quantum-secure technology for trading tokenised physical gold.
This collaboration marks a significant advancement in safeguarding digital assets against future quantum threats.
The successful trial of quantum-safe cryptography for tokenised gold trading demonstrates a proactive approach to cybersecurity in finance.
It addresses the 'store now, decrypt-later' risk, where data stolen today could be decrypted by future quantum computers.
This innovation sets new standards for protecting digital assets and maintaining trust in the evolving financial ecosystem.
HSBC pioneering quantum-safe security in digital asset trading
In 2023, HSBC became the first global bank to offer tokenised physical gold to institutional investors using DLT.
This system uses a decentralised digital network to record transactions across multiple computers, enhancing security and transparency.
Philip Intallura, Global Head of Quantum Technologies at HSBC, explains: "HSBC was the first international bank to offer tokenised physical gold and is now building on that innovation with cutting-edge cybersecurity protection for the future."
Building on this initiative, HSBC expanded its offering this year with the launch of HSBC Gold Token for retail investors in Hong Kong, enabling fractional ownership of physical gold and democratising access to this asset class.
Quantum-safe technology: the next frontier in cybersecurity
As part of the trial, HSBC tested the interoperability of its gold tokens using post-quantum cryptography (PQC).
This set of cryptographic algorithms is designed to withstand attacks by quantum computers, which are expected to render many current encryption methods obsolete.
The bank demonstrated the ability to convert its gold tokens into ERC-20 fungible tokens, a technical standard for tokens on the Ethereum blockchain.
This conversion enhances the tokens' utility and interoperability within the broader digital asset ecosystem.
Quantinuum employed PQC algorithms and its proprietary Quantum Origin quantum randomness technology to showcase comprehensive protection of digital assets from quantum computing attacks.
Addressing the 'store now, decrypt-later' threat
The trial also addressed the threat of "store now, decrypt-later" (SNDL) cyber incidents.
This technique involves malicious actors stealing sensitive data with the intention of decrypting it later using powerful quantum computers that do not yet exist.
Philip notes: "By addressing SNDL threats, we're not just preparing for the future; we're actively shaping it. This breakthrough demonstrates that we can future-proof our digital asset offerings against potential quantum computing threats."
Implications for cybersecurity in financial services
The successful trial of quantum-safe technology for tokenised gold trading has significant implications for cybersecurity in financial services.
As digital assets become increasingly mainstream, robust security measures that can withstand future technological advancements are crucial.
The integration of quantum-safe technology with tokenised assets also opens up new possibilities for cross-platform interoperability.
This could potentially lead to more efficient and secure trading of digital assets across different blockchain networks and traditional financial systems.
As quantum technology continues to advance, the ability to protect digital assets from both current and future threats will likely become a key differentiator for financial institutions in their cybersecurity strategies.
Philip concludes: "By combining tokenised assets with quantum-safe technology, we're creating a new standard for security and innovation in digital finance.
“This isn't just about protecting assets; it's about building trust in the digital financial ecosystem of the future."
Ilyas Khan, Quantinuum founder and Chief Product Officer, elaborates: "As long-time partners in exploring commercial quantum applications, HSBC and Quantinuum are together building the next generation of financial services featuring quantum-hardened defences harnessing the power of today's quantum computers to safeguard sensitive data now and into the future."
