Post-Quantum Cryptography for Defence and Governmental Applications: Overview and Use Cases

Abstract

Protecting the Military against the Quantum Threat to Today’s Cryptography.

Quantum computers have the potential to break many of the currently used cryptographic schemes, such as RSA and ECC, due to their ability to efficiently solve certain mathematical problems. Post-quantum cryptography is a class of cryptographic algorithms that remain secure even in the presence of powerful quantum computers, thus ensuring the continued security of sensitive information in the future.

PQC solutions can help upgrade hardware (such as vehicles, sensors and hardware security modules) and software (such as public key infrastructure, TLS and virtual private networks) to become crypto-agile and quantum-resistant. Classified data held by defense and aerospace organizations can have a long shelf-life, and even now is at risk of interception and future decryption.
