How to protect yourself
From the banking sector, CaixaBank addresses the quantum threat “understanding that it is a real risk and, as such, must be managed proactively,” a company representative said via email.
“The risk is already relevant, and it is necessary to have mitigation measures in place now,” the representative continued. “At the same time, the approach is not simply to replace one encryption algorithm with another, but to equip the bank with the necessary crypto agility to be able to rotate keys, change cryptographic models, or adopt new standards quickly and in a controlled manner when necessary. In this way, not only is this specific threat mitigated, but the bank’s resilience and preparedness for future technological changes are structurally strengthened.”
The firm itself is already developing a comprehensive plan, currently under way, with 2029 as the target date for a robust crypto-agility model. This plan has two complementary dimensions. On the one hand, it includes the new PQC schemes, which the bank is currently analyzing to determine how they can be incorporated in an orderly fashion.
