Hardware security plays a critical role in the aerospace field across multiple dimensions:
Mission-Critical Reliability: Aerospace systems, such as satellites, aircraft, and spacecraft, rely on hardware that must operate flawlessly under extreme conditions. Secure hardware ensures no unauthorized tampering or failures that could jeopardize missions. For example, a satellite's onboard computer must resist physical or cyberattacks to maintain communication and navigation functions.
Data Protection: Aerospace systems handle sensitive data, including telemetry, navigation, and defense-related information. Hardware security measures like secure enclaves and cryptographic accelerators prevent data breaches. For instance, military drones use hardware-based encryption to safeguard real-time intelligence.
Supply Chain Integrity: Aerospace hardware components often pass through complex supply chains. Secure hardware, such as tamper-resistant chips, ensures components are not compromised during manufacturing or delivery. An example is the use of physically unclonable functions (PUFs) to verify the authenticity of avionics components.
Resilience Against Cyber-Physical Attacks: Aerospace systems are vulnerable to cyber-physical threats, where attackers exploit hardware vulnerabilities to disrupt operations. Hardware security features like firewalls and intrusion detection systems embedded in flight controllers can mitigate such risks.
Compliance with Standards: Aerospace hardware must meet stringent security standards, such as DO-178C for software and DO-254 for hardware in avionics. Compliance ensures reliability and security in airworthiness certifications.
