Banco Sabadell Partners with Accenture, QuSecure to Adopt Post-Quantum Cryptography

Spanish financial services company Banco Sabadell, in partnership with Accenture and QuSecure, has successfully completed a project to explore the adoption of post-quantum cryptography (PQC) technologies within its infrastructure.

This initiative strengthens the bank’s defences against potential quantum attacks. It modernises encryption using QuSecure software and open-source libraries.

The four-month project provided Banco Sabadell with a roadmap for becoming quantum-resilient and demonstrated how quantum security technologies can be implemented effectively. 

“This project, in collaboration with Accenture and QuSecure, has allowed us to explore the impact of the adoption of PQC technologies on the bank's infrastructure,” said Joan Puig, Group CISO at Banco Sabadell.

Cryptography plays a vital role in securing banking processes like payments and communications, which are increasingly vulnerable to emerging quantum threats. 

“As we transition into a post-quantum computing era, the challenges include identifying cryptographic methods vulnerable to quantum attacks and transitioning to quantum-safe cryptography with agility and efficiency,” Puig explained.

Accenture brought its expertise in quantum risk and security to the project, helping Banco Sabadell develop a clear roadmap based on the latest NIST PQC standards.

“This collaboration underscores our commitment to helping organisations safeguard their data from emerging threats posed by the rapid quantum computing advancements,” said Tom Patterson, emerging technology security lead at Accenture.

QuSecure highlighted the ease of implementing quantum-safe technologies without overhauling existing systems. “This proves that mitigation of existing encryption to post-quantum standards for complex environments is possible and can be achieved expediently this decade,” said Elizabeth Green, SVP customers and ecosystems at QuSecure.

As quantum computing advances, preparing for its impact on cryptography becomes increasingly critical. The project reflects Banco Sabadell’s proactive efforts to secure its systems and data and ensure their protection in the post-quantum era.
