AbstractThis paper proposes a methodology for the secure recovery of spacecrafts and the recovery of its cryptographic capabilities in emergency scenarios recurring from major unintentional failures and malicious attacks. The proposed approach employs trusted modules to achieve higher reliability and security levels in space missions due to the presence of integrity check capabilities as well as secure recovery mechanisms. Additionally, several recovery protocols are thoroughly discussed and analyzed against a wide variety of attacks. Exhaustive search attacks are shown in a wide variety of contexts and are shown to be infeasible and totally independent of the computational power of attackers. Experimental results have shown that the proposed methodology allows for the fast and secure recovery of spacecrafts, demanding minimum implementation area, power consumption and bandwidth.
