| Résumé : | In this thesis, an in-depth examination of current CubeSat architectures is carried out,followed by a comprehensive threat analysis to identify and assess potential security vulnerabilities. Based on the literature study and current CubeSats architectures, a newarchitecture is proposed that incorporates SRAM PUF modules for secure, lightweight internode communications.Using the proposed architecture, a test bed is developed, implementing the secure lightweightinternode communication protocol based on PUF technology.The architecture and protocol are verified through unit, and system testing, followed byexperimentation to assess computations overhead of the secure features implemented.Finally a new threat analysis is conducted on the newly proposed implementation andarchitecture, highlighting its effectiveness and potential areas for improvement. |
