We are thrilled to share some exciting developments from our latest project, FYSON, conducted under an ESA contract using the ESA OPS-SAT satellite. This demonstration marks a pivotal moment in space communication, showcasing groundbreaking technologies in a real space environment.

As we venture deeper into space, the importance of cybersecurity becomes even more pronounced. At Skudo, our passion for space exploration led us to develop the FYSON project, an initiative that stands for "For Your Eyes Only". But what does this mysterious name signify, and how is it propelling us into the next frontier of space technology?

Deciphering FYSON

At its core, the FYSON project encapsulates a robust encryption mechanism, ensuring that data transmitted from satellites is solely decipherable by the intended recipient. This is achieved by employing a specialized encryption wherein only the designated user, possessing the correct digital certificate (or key), can decrypt and access the data. It’s a digital whisper from the satellite, meant only for those chosen ears.


A recent Forbes article ( highlighted the growing need for cybersecurity in space systems and satellites. As noted, space assets are vulnerable to sophisticated threats. Yet legacy security methods are inadequate for modern missions. This underscores the value of our integrated hardware encryption technology demonstrated via our FYSON project with ESA.

The article outlines several factors making security crucial for space systems:

Skudo is thrilled to announce a new technology demonstration that will securely transmit enhanced imagery of Earth from space. In partnership with the European Space Agency (ESA), we will upload an innovative hardware security module (HSM) implemented in Verilog code to the OPS-SAT satellite currently in orbit. This groundbreaking HSM module leverages a separate RISC-V processor core to locally enhance images before encrypting them for transmission using the digital certificate of the intended receiver on Earth.

Zero Trust Architecture (ZTA) is a security model that focuses on verifying and securing all devices, users, and data before granting access to any resources. In this model, trust is never assumed, and all requests must be authenticated and authorized before being granted. This approach helps to prevent data breaches and cyberattacks, as it minimizes the attack surface and reduces the risk of unauthorized access.

As quantum computing continues to advance, the potential for quantum computing threats to traditional cryptographic methods has become a major concern in the field of #cybersecurity. In the realm of space communication, the use of agile cryptography can be an effective way to protect against these threats and ensure the continued #spacesecurity and #satellitesecurity of these systems.

In the rapidly evolving world of space communication, it is important to have the ability to quickly adapt to changing security needs. Agile cryptography is a concept that involves the use of adaptable cryptographic algorithms and protocols that can be modified in response to changing security requirements.
