TELETEL serves as the Technical Coordinator of the “European cybersecurity HSM/TPM device for securing micro/nano satellite and UAV communications” (HSM4COM) project, which is a 3-year EDF project coordinated by Miltech Hellas that started on 1st April 2025.

Its consortium gathers 7 partners from 4 European countries: Miltech, Teletel, Hellenic MoD, Skudo, DefSecIntel, Osmium and Argotec.

The HSM4COM project will develop a hardware device combined with a secure operating system for securing the processing chain and data communications in micro-satellites, Unmanned Aerial Vehicles (UAV), Unmanned Ground Vehicles (UGV), Autonomous Surface Vehicles (ASV) and others. The HSM4COM solution will be capable of providing encryption, decryption and attestation functionalities. The combined hardware/software device will constitute a generic highly customisable solution for both microsatellite and UAV platforms, being also applicable for use in UGV/ASV and other similar platforms.

TELETEL is the integrator of the HSM4COM solution and will perform compatibility assessment activities to ensure seamless integration and interoperability with Hybrid multi-role UAVs and Micro-satellite platforms.
