Abstract

This paper investigates the immediate threat posed by quantum computing to Canada’s military communication networks, particularly its reliance on classical encryption methods for NATO defense operations. As quantum computing approaches the ability to break traditional encryption, Canada faces the urgent need to secure its communication channels to ensure operational security within the NATO framework. The paper presents a targeted roadmap for transitioning Canada’s military communications to quantum-safe encryption over the next 3-5 years, with a specific focus on post-quantum cryptography (PQC) and quantum key distribution (QKD) technologies. Key policy, technical, and strategic steps are outlined, including collaboration with NATO and global partners.


Introduction

As global quantum computing advancements continue, Canada’s military communication networks face a looming vulnerability that could compromise sensitive defense operations. These networks, integral to NATO’s defense framework, rely on classical encryption methods—specifically RSA and AES—to secure communication. However, the advent of quantum computers capable of breaking these encryption protocols threatens Canada’s security and its role within NATO. The paper proposes a concrete, actionable roadmap to secure Canada’s military communication systems with quantum-safe encryption. This roadmap will ensure Canada’s defense networks remain secure and functional in a post-quantum world, particularly in the context of NATO’s collective defense and interoperability needs.


Problem: Quantum Vulnerability in Canada’s Military Communication Networks

Canada’s military communications, especially those that rely on NATO-integrated systems such as the NATO Integrated Communications System (NICS), are vulnerable to attacks by quantum computers. Current encryption standards like RSA and AES, which secure these communication channels, would be easily decrypted by quantum algorithms, particularly Shor’s algorithm. This situation presents a direct threat to the confidentiality, integrity, and operational security of Canada’s military communications, which are vital for secure defense coordination within NATO. If quantum-powered adversaries, particularly China and Russia, exploit this vulnerability, it could lead to a significant breakdown in defense cooperation and compromise sensitive data exchanges.

The core issue, therefore, is that Canada’s reliance on outdated encryption systems for critical military communications, coupled with the rise of quantum computing, creates an immediate need for quantum-safe encryption solutions to safeguard Canada’s security and NATO’s collective defense strategy.


Solution: Transition to Quantum-Safe Encryption for Military Communication Networks

To mitigate the threat posed by quantum computing, Canada must transition its military communication networks to quantum-safe encryption solutions. This paper proposes a focused, 3-5 year roadmap for Canada to implement post-quantum cryptography (PQC) and quantum key distribution (QKD) technologies in its defense communication systems. These technologies will safeguard Canada’s communications from quantum-enabled cyber threats and maintain the integrity of NATO defense operations.
