Secure computing is vital for space missions, where systems face harsh environments, limited maintenance, and threats like cyber-attacks and radiation. This presentation explores industry security techniques, focusing on the PIC64-HPSC, a 64-bit microprocessor from Microchip Technology designed for high-performance spaceflight computing with robust security features.

Key Security Requirements and Trends:

• No Unencrypted Keys: Uses a Physical Unclonable Function (PUF) for unique, hardware-based key management.

• Standardized Cryptography: Employs NIST-certified algorithms for compliance.

• Quantum Resistance: Integrates post-quantum cryptographic algorithms to counter quantum computing threats.

• Immutable Storage: One-Time Programmable (OTP) memory secures critical data.

• Trusted Initialization: Secure boot ensures only trusted software runs at startup.

• Hardware Isolation: WorldGuard architecture supports up to 32 domains for isolating workloads.

• Layered Security: Combines secure boot, post-quantum cryptography, user-level security acceleration, and anti-tamper features.

• Runtime Monitoring: A dedicated system controller CPU core handles fault detection and oversight.

• Isolated Security Services: A secure controller CPU core manages secure boot, key management, authentication, code rollback protection, key revocation, and random number generation.

Manufacturing and Supply Chain: Mitigating supply chain risks is crucial. Cryptographic controls verify device authenticity and prevent tampering during production and distribution, with zeroization at end of life.

Conclusion: Space mission security demands comprehensive techniques to address conventional and emerging threats, ensuring reliable spaceflight computing systems.
