Post-Quantum Encryption

Encryption systems for communication channels that are resilient to attacks from both quantum and classical computers. A security architecture designed to withstand the post-quantum era.

What is Quantum Computing?

Quantum computing breaks classical cryptographic algorithms (RSA, ECC) through exponential acceleration. Post-quantum cryptography is the set of algorithms that are mathematically resistant to this computational power, and it was adopted by NIST in 2024 as the new global security standard.

The problem

The "Harvest Now, Decrypt Later" threat

The “Harvest Now, Decrypt Later” threat is already a reality for organizations that manage sensitive information and critical assets. This approach involves intercepting and storing encrypted data today in order to decrypt it in the future using quantum computing capabilities, thereby compromising communications, operational secrets, intellectual property, and strategic information. The risk is particularly high in systems where information must remain confidential for years or even decades.

The solution

Algorithms resilient to both worlds

The answer is to adopt cryptographic algorithms that are resistant to both classical and quantum attacks. Quantum-safe PQC architectures enable the protection of long-lifecycle data, systems, and communications, ensuring resilience, operational continuity, and digital trust in defense, government, space, and critical infrastructure environments. Furthermore, they facilitate an orderly transition to new security standards without compromising interoperability or operational performance by reusing current hardware, as they run on the same existing infrastructure.

What We Offer

We support the transition of critical infrastructure to cryptographic schemes prepared for the post-quantum era, minimizing operational risks and ensuring service continuity. We assess dependencies, prioritize sensitive assets, and define migration roadmaps tailored to defense, government, energy, telecommunications, and space systems environments.

Our approach combines diagnostics, architecture, implementation, and technical support to gradually replace vulnerable algorithms with quantum-safe capabilities. This strengthens long-term resilience, protects strategic information, and ensures interoperability with legacy systems and new platforms.

We design digital identity solutions, robust authentication, and secure electronic signatures for environments where trust, traceability, and integrity are essential. We protect critical validation, access, and authorization processes in organizations that handle sensitive information, command chains, distributed systems, and high-value assets.

We integrate advanced cryptographic mechanisms and governance models that strengthen the lifecycle of credentials, certificates, and digital signatures. The result is a more reliable infrastructure for critical operations, secure information exchange, and compliance with regulatory requirements and technological sovereignty.

We develop hybrid encryption architectures that combine classical technologies with advanced quantum-resistant security capabilities to protect highly sensitive links. We design solutions for fiber networks, private networks, optical channels, and distributed environments that require high availability, low latency, and maximum operational reliability.

Quantum-safe solutions that integrate post-quantum cryptography, key protection, and resilience mechanisms tailored to critical infrastructure, all without disrupting existing operations. These solutions are particularly relevant in ground-to-space scenarios, control centers, government networks, and essential services.

We help public and private organizations adapt their security strategies to new requirements for compliance, cryptographic resilience, and data protection in the quantum context. We assess exposure, criticality, and regulatory obligations to align technological evolution with national and international regulatory frameworks.

Our approach strengthens data sovereignty, cryptographic governance, and control over infrastructure, communications, and strategic assets. This enables organizations to anticipate regulatory risks, strengthen audits, and ensure an orderly transition to security models prepared for future threats.

and Technologies We Use

Why implement it now?

01/

Migration can't wait

The transition to quantum-resistant cryptography requires time, prioritization of assets, and adaptation of legacy systems. The more critical the infrastructure and the longer the data’s lifespan, the less room there is to delay decisions regarding migration and cryptographic resilience.

02/

Data is already being collected today

The “Harvest Now, Decrypt Later” model makes long-term protection a priority. Strategic information, encrypted communications, and sensitive assets can be intercepted today and decrypted in the future, compromising operations, intellectual property, and technological sovereignty.

03/

Continuity must be ensured

Adopting quantum-safe models is not just about implementing new algorithms; it is about ensuring continuity, interoperability, and operational reliability during the transition. Preparing now helps reduce risk, avoid reactive migrations, and protect essential services in critical environments.

04/

Being proactive gives you an edge

Organizations that integrate PQC, QKD, and advanced intelligence capabilities early on strengthen their security posture and response capabilities. Taking a proactive approach not only reduces future exposure but also improves compliance, data sovereignty, and technological readiness for high-stakes scenarios.
