Update Reason: Tender issue

Today, critical safety and security functions in spacecraft (S/C) avionics are implemented in ASIC or one-time programmable FPGAs. Neither allows an update to add functionality or correct implementation errors post-launch.The speed of security and safety-relevant technology development is expected to grow further, in the areas of- Mathematics: cryptography, coding theory- Electrical engineering: signal processing, growing scope for firmware-defined functions like Software Defined Radio- Computer Science: efficient algorithms, new computer architectures and even computing paradigms like the quantum computerThese trends make it more likely that critical S/C avionic functions will require an update over the course of the S/C mission: Cryptanalytic advances or a large-scale quantum computer may create the necessity to replace certain cryptographic algorithms during a mission lifetime. Similar arguments hold for updating TTC or payload waveforms, anti-jam function and communication codes. Also, increased functional complexities may increase likelihood post-launch implementation error correction or functional enhancement, also e.g. For the hardware reconfiguration module of an on-board computer.Certain Telecom missions today require the physical embedding of a non-european TTC security module. The technology to be developed under this activity can allow for reconfiguring an on-board security module to meet regulatory security requirements of different markets over S/C lifetime.In-flight hardware reprogramming as such has already been studied. New technology here is the novel cryptographic signature: Merkle-Tree digital signature, agreed by security experts worldwide to provide long-term security. For safety and security reasons, the update function itself is to be implemented by non-updatable hardware, hence a long-term secure cryptographic signature algorithm is required for the update process.This activity encompasses the following tasks:- develop functional concept for safely and securely conducting the re-programming of a device in the highly safety-critical path of SC telecommanding, including deactivation of the old and activation of the new functions following the actual reprogramming process;- trade-off different implementation technologies and architectures;- design and build a breadboard implementing the core building blocks of secure re-programmability of a cryptographic TTC security module.
