Title:
T603-35GI
Security communications for SLE services
Based on precedent System studies and the existing CCSDS Space Link Extension (SLE) transfer services and
implementation by both ESA and NASA, this study aims at reviewing and upgrading the Security functions for missions where
a high-level of Security might be requested.
The Study will have to consider the available protocol and design the tools (e.g. protocols, encryption methodologies, etc.)
needed to implement a high level of security that can be provided with ad hoc tailoring to a user mission. All the design
choices shall be supported by Software breadboarding and simulation. The developed software shall be organized in form of
Software Product (e.g. Library) for easy portability and integration in existing or proprietary software (sub)systems.
Deliverables:
Technical note, SW breadboard and simulation.

Title:
Feasibility of Automated Regression Testing for Space Systems Operational Software
The operational S/W used within space systems is constantly increasing its complexity. Furthermore, due to standardisation
and re-use of infrastructure systems, the expected lifetime of software components has also significantly increased. These
trends have lead to a significant increase in the efforts required for system verification and validation, in particular to ensure
integrity of previously validated functions (regression testing) when delivering a new version of the same software
component/system. Currently, the vast majority of all testing activities, including regression testing, are performed based on a
'manual' approach with the human in the loop. This is primarily due to the fact that, in order to automate testing activities, a
large effort has to be invested upfront for the definition of appropriate test data, test tools/harnesses, test procedures and test
outputs evaluation (pas/fail criteria). The proposed study should therefore demonstrate the feasibility and assess the benefits
of adopting an automated approach for the execution of software systems regression testing. It will include the analysis of the
specific features of space systems software components, with particular attention to the ground operations systems that are
typically operated by humans via human-machine interfaces, and it will review the possible options offered by available
technologies and commercial products for the preparation and automatic execution of systems regression testing. The
selected approach shall be suitable for automated testing of all ground operations systems i.e. it shall not be bound to the
specific implementation aspects of the individual systems. A demonstration test environment will be set-up covering the
automatic execution of functional and non-functional tests of selected software components. This prototype shall demonstrate
the re-usability of the automated test cases when validating a new version of the same software component. Finally, it will be
assessed the required effort for the set-up of the individual test cases and evaluation of the potential benefits of the
demonstrated approach. Special emphasis shall be given to the feasibility of identifying unambiguous pass/fail criteria for each
test case, with particular reference to the non-functional tests.
Deliverables:
Technical documents (adoption of automated approach for execution of SW sys regression testing). Set-up of demonstration
test environment + data/procedures. Final report (assessment of the potential benefits / relevant recommendations).
