Hardware-rooted cryptography in reconfigurable FPGA hardware, with reusable cryptographic IP, post-quantum capability and secure SoC building blocks.
Explore custom workTechnology
Skudo develops cryptographic functions directly in FPGA hardware, reducing reliance on general-purpose operating systems and software-based key storage. Reconfigurable hardware also allows security functions to evolve as requirements and standards change.
Skudo provides FPGA-based implementations of ML-KEM and ML-DSA, extending hardware-rooted security into the post-quantum era. These capabilities can be used alongside established classical cryptography, supporting crypto-agile architectures that can evolve as security requirements and standards change. The approach is particularly relevant for defence, space and other long-lifecycle systems where communications and protected data may need to remain secure for many years.

Track record
Skudo has built a long-running relationship with the European Space Agency through multiple completed and ongoing development contracts in space cybersecurity, hardware-rooted cryptography and secure embedded systems. This includes the FYSON project, where Skudo’s hardware encryption technology was successfully demonstrated in orbit on ESA’s OPS-SAT satellite. The OPS-SAT demonstration is one milestone within a broader portfolio of ESA activities rather than a standalone project.
