We are changing the world

Our vision

We see cryptography as a technology for fixing the faults that computers have had since they were first built. Computers were built to copy data, not to keep it secret. Properly implemented cryptography can achieve that.

What we’re doing

We are working on bringing cryptographic technologies for security and privacy from research to real life. We advise our customers on their transition to a quantum-safe future. We design and implement post-quantum components for our own products and the systems of our customers.

How we’re doing it

We have researched fundamental PQC technologies and solutions since 2017. This allows us to address the post-quantum transition in many industries and systems. We continue to research new technologies and work with standards bodies and regulators to ensure that our offerings are efficient and rely on proven standards where available.

Preparing for quantum-safe systems

The world of cryptography will go throught a tectonic shift.
A reasonably powerful quantum computer, if built, may solve the hard mathematical problems on which our current cryptography relies on.

Post-Quantum Cryptography (PQC) is a new set of algorithms for which no attacks are yet known on quantum or standard computers. PQC does not rely on the hardness of finding prime factors of very large integers or finding discrete logarithms. PQC does not require a quantum computer, it can be implemented and run on commodity devices and servers today.

In most systems, migrating to post-quantum cryptography will be a software upgrade.

Our offering

Migration to post-quantum cryptography: We identify cryptographic assets, systems and products to upgrade them to quantum safe versions.
Achieving cryptographic agility: We build cryptographic systems to make their use of cryptography modular, ensuring that they can be kept up to date as new standards and certifications start to apply.
Designing protocols for complex systems: We design and implement cryptographic systems for document encryption, authentication, digital signatures, privacy preservation and internet voting.
Building systems with modern cryptography: We offer design and engineering services to develop systems using secure multi-party computation, zero knowledge proofs, homomorphic cryptography and more.
Guidance and roadmaps: We partner with governments and industry to develop cryptographic policies and set in structured roadmaps.
Assessment and evaluation: We perform theoretical and practical analysis of schemes, protocols and systems using protocol analysis, formal methods and code reviews.

Proven track record

Post-quantum cryptography transition for Estonian e-governance

Three strategic contracts were awarded to Cybernetica by the Estonian government to lead the transition of national e-governance systems to post-quantum cryptography (PQC). The project safeguards Estonia's core digital infrastructure, including eID solutions, the X-Road platform, and the internet voting system, against quantum computers capable of breaking conventional algorithms such as RSA and elliptic curve cryptography. The work encompasses a national PQC roadmap, a quantum-risk assessment of the Population Register, and an updated lifecycle research report on cryptographic algorithms. This programme positions Estonia ahead of the EU's 2030–2035 quantum-transition deadlines, with Cybernetica at the helm.

Privacy-preserving satellite collision avoidance using secure multiparty computation

A privacy-preserving satellite collision avoidance system enables operators to jointly assess collision probability without exposing sensitive orbital data. Built on Sharemind MPC, Cybernetica's secure multiparty computation platform, the system allows encrypted data from multiple parties to be analysed without any single party accessing the others' inputs. First prototyped under the DARPA PROCEED programme in 2015, the work has continued through the ShareSat project supported by the European Space Agency, allowing operators to share computed collision risk, but not satellite trajectories or technical specifications, protecting commercial and national security interests while contributing to safer orbital operations.

Zero-knowledge proof system for privacy-preserving vehicle location compliance

A zero-knowledge proof (ZKP) system for location and mobility verification was designed and prototyped under the US DARPA SIEVE programme. The project enabled individuals to prove compliance with mileage and territory-based requirements, such as electric vehicle subsidy conditions, without disclosing their GPS trail to any third party. The system comprised a local-storage GPS tracker, a smartphone app computing trip aggregates, and a ZKP module generating cryptographic proofs verifiable without revealing the underlying location data. Built on Cybernetica's ZK-SecreC toolkit and demonstrated at the Pentagon Demo Day in 2023, the solution shows how cryptography can enable regulatory compliance while preserving individual privacy.

Threshold cryptography-based key protection for EU Digital Identity Wallets

A software-based, distributed Wallet Secure Cryptographic Application (WSCA) architecture for the European Digital Identity Wallet was developed, addressing secure cryptographic key management at EU-wide scale. The solution is based on Cybernetica's SplitKey threshold cryptography architecture, which distributes private key operations so that no single point of compromise can expose user credentials. It supports hundreds of key pairs per wallet, decoupled authentication, and post-quantum cryptographic algorithms. Operational proof comes from the Smart-ID system, serving 3.5 million users at the eIDAS "high" assurance level. Cybernetica is also contributing to CEN/CENELEC TC224 WG17 to establish a formal Protection Profile for distributed WSCAs, enabling independent evaluation and confident procurement by EU member states.

Building awareness

We help spread the word about post-quantum cryptography through various channels and events, including our own Future Cryptography conference, where researchers, practitioners, and enthusiast come together to discuss the latest developments in the field.

We invest in education, teaching classes to students, supervising works and engaging the public. In 2025, we partnered with the OpenSSL Foundation to promote transition to post-quantum cryptography with the Post-Quantum Trails board game.
