Quantum computing threatens the cryptography protecting satellites and critical infrastructure

Bookmark this story

Cryptographic systems relied on for decades to secure sensitive communications and critical infrastructure could become vulnerable to sufficiently powerful quantum computers. Satellite operators and space-system developers face a long-term security challenge involving the protection of command, control and data links against future quantum-enabled attacks.

Briefing

What Hype is tracking

  • Satellite communications and command links depend on cryptography to protect sensitive data and critical infrastructure.
  • The emergence of sufficiently powerful quantum computers could undermine encryption methods that have protected these systems for decades.
  • Quantum resilience is therefore a strategic design and lifecycle issue for satellite operators, manufacturers and users of space-based infrastructure.
