Strengthening Defence capability through digitised cryptographic asset management

Modern Defence operations depend on assured, resilient, and scalable cryptographic capabilities. Yet many environments still rely on manual, paper-based processes for cryptographic accounting and lifecycle management. These approaches, while historically effective, now introduce operational risk, limit visibility, and constrain responsiveness.

CGI’s Crypt-Key (CK) capability enables Defence organisations to transition to a secure, digitised model for cryptographic asset management. By delivering real-time visibility, end-to-end lifecycle control, and auditable governance aligned with MOD and NCSC standards, CGI helps strengthen mission assurance, reduce risk, and improve operational efficiency across high-assurance environments.

Context

Defence operations increasingly rely on secure, trusted communications and assured data integrity across complex, distributed, and contested environments. Cryptographic systems underpin this trust. When cryptographic control is robust, operations remain secure and effective. When it is not, the consequences can directly affect mission success. Despite this, many Defence organisations continue to depend on fragmented and paper-based cryptographic management processes. These methods were designed for a different historic operational context and now struggle to meet the demands of modern Defence.

The operational challenge

Manual and disjointed cryptographic management introduces critical vulnerabilities principally to key distribution challenges.

• Limited real-time visibility of cryptographic assets across operational environments, leading to reduced auditability and compliance assurance
• Increased risk of loss, compromise, or mismanagement
• Slower response times in key distribution and lifecycle operations
• Difficulty scaling to support modern, distributed Defence operations

In the face of sophisticated cyber threats and capable nation-state adversaries, these limitations are no longer sustainable. Moving forward two technology solutions will most likely become dominant in the market based on well-known commercial products in the marketplace;

1. Asymmetric key encryption will be one way forward. This means that all key distribution will be electronic and therefore any system will not have to deal with the inherent complexities associated with physical key distribution systems.

2. Electronic symmetric key distribution, either via asymmetric key distribution or confirmed trusted initial symmetric key (an initial wrapping key) followed by rotation of said wrapping symmetric key.  Subsequent encryption would then be performed by the wrapped short lived symmetric key.

Why this matters now

Defence organisations and contractor organisations critical to supporting operational systems must be able to maintain continuous operational readiness while ensuring end-to-end security assurance, demonstrate full accountability and auditability whilst operating with speed and agility at scale. Cryptographic management is no longer a back-office function, it is a mission-critical capability. When taken through a structured digitisation framework it can enable Defence to transition from reactive, manual processes to a proactive, controlled, and resilient operating model.

Benefits of digitisation

A modern, digitised approach to cryptographic asset management delivers measurable advantages:

• Mission assurance - Real-time visibility and control reduce operational risk and support uninterrupted mission delivery.
• Operational efficiency - Automation streamlines lifecycle management of cryptographic assets and keys, significantly reducing manual overhead and accelerating distribution and rotation processes.
• Security and compliance - Comprehensive audit trails provide full traceability and alignment with MOD and NCSC standards, improving assurance and inspection readiness.
• Resilience - Centralised governance and reduced reliance on manual processes minimise exposure to human error and insider threats.
• Scalability - Supports complex, multi-domain and geographically distributed Defence environments, including those involving industry partners.

While digitisation introduces considerations such as system complexity and cyber exposure, these risks can be effectively mitigated through secure-by-design architectures and robust governance frameworks.

Enabling successful transformation

Successful digitisation is not solely a technology challenge. It requires a coordinated approach across people, process, and governance, Key success factors include:

• Clear leadership and strategic direction, aligned to organisational processes and operating models
• Structured digital maturity progression, supported by a Digital Roadmap. 
• Effective training and adoption across user communities

As a digital transformation partner, CGI understands and can support Defence organisations through this journey, ensuring new capabilities are fully adopted, integrated, and effective, contributing to:

• Enhanced mission effectiveness and strengthened national security posture
• Reduced operational risk, Improved compliance and assurance
• Long-term resilience against emerging threats

Crucially, this approach reinforces sovereign capability, ensuring that critical cryptographic functions remain under trusted national control.

CGI’s proven approach

CGI delivers a mission-assured Crypt-Key (CK) management capability designed specifically for high-assurance Defence environments. Our approach combines secure technology delivery with organisational transformation, ensuring that digitisation enhances, rather than disrupts operational capability. This capability is already operational within high-classification environments, supporting Defence organisations in transitioning away from legacy processes. 

Conclusion

As Defence continues to modernise, the ability to securely manage cryptographic assets at scale is fundamental to maintaining operational advantage. CGI combines deep expertise in cryptography, cyber security, and Defence digitisation with a proven delivery track record in classified environments. Our assurance-led approach enables Defence customers to transition confidently from legacy processes to a secure, scalable, and future-ready cryptographic management capability.
