Sopra Steria, one of the leading European players in the technology sector, has announced the integration of post-quantum hybrid cryptography into its security solution Datasphere. This strategic move aims to stay ahead of the impact of quantum computing on global cybersecurity.
The company emphasizes that this development represents a major leap in protecting sensitive data, especially at a time when the rapid advancement of computing power threatens to render traditional cryptographic algorithms obsolete, which today ensure the confidentiality and integrity of information.
Why Post-Quantum Cryptography Matters
Experts agree that the advent of quantum computing will jeopardize current encryption algorithms, including those underpinning security in banking, defense, telecommunications, and critical infrastructure. In this context, post-quantum cryptography (PQC) is no longer optional but an urgent necessity.
Datasphere, already used by civil, industrial, and defense organizations, offers features such as document tagging and marking, data encryption, and attribute-based access control. Now, with the hybrid post-quantum layer, the solution combines classical algorithms with schemes resistant to quantum threats, providing:
- Sustainable protection of sensitive data against future threats.
- Compliance with NIST recommendations, which promote the transition to hybrid post-quantum schemes.
- Interoperability with international standards, including those defined by NATO and European cybersecurity agencies.
- Flexibility in the transition, allowing organizations to continue using existing infrastructures while progressing toward fully post-quantum environments.
A Step Toward European Digital Sovereignty
This integration also aligns with a strategic goal: strengthening digital sovereignty. As Thierry Lempereur, Director of Defense and Security at Sopra Steria, states:
“With this evolution, we are preempting future threats today. The hybrid post-quantum cryptography integrated into Datasphere enhances our clients’ digital sovereignty while providing a pragmatic and interoperable solution. It’s a crucial step for the long-term protection of data, which is a strategic resource at the core of any organization.”
International Context and Next Steps
The race for post-quantum cryptography is influenced by initiatives such as the NIST (USA), which in 2022 selected the first standardized algorithms resistant to quantum attacks, and by NATO, which is promoting guidelines for its member countries to strengthen their communication and defense systems.
In Europe, adopting hybrid schemes is considered the most realistic path to ensure a secure transition, balancing interoperability with protection against threats that, although still emerging, are inevitable.
With this announcement, Sopra Steria establishes itself as a European leader in sensitive data security and provides governments, strategic businesses, and defense entities with a tool to navigate the coming decade of transition toward the post-quantum paradigm.
FAQ
What is post-quantum hybrid cryptography?
It’s an approach that combines classical encryption algorithms with those that are resistant to quantum computer attacks, ensuring protection against both current and future threats.
Why is this important for businesses and governments?
Because current encryption systems, like RSA or ECC, could be broken by quantum computers, risking strategic data in sectors like banking, defense, or healthcare.
What advantages does the hybrid model offer over a direct migration?
It enables compatibility with existing infrastructures, reducing costs and risks during the transition while ensuring robust protection.
What role does Europe play in this transition?
The European Union and NATO are promoting common standards for quantum security. Solutions like Datasphere strengthen European strategic autonomy by reducing dependence on external providers.
