SplitKey – unique technology

Cryptographic Solution
SplitKey technology is based on proven principles of public key cryptography, digital signature schemes, and PKI. Public key cryptography works on the concept of key pairs:

  • the public key is bound with the verified identity of the user
  • the private key is confidential and protected, e.g. inside a
  • smart-card, which is under sole control of the user

Digital signing
SplitKey ensures that only the user can sign or approve a transaction, due to the user retaining one piece of their private key which never leaves theirdevice. SplitKey complies with the European QSCD (Qualified Signature Creation Device) requirements and PSD2 (Payment Services Directive).

Access authentication
SplitKey provides secure but simple authentication for accounts that require superior online security. Banking sites, trading platforms, government department sites, or any online portal can protect its users’ accounts by ensuring that only the user has control of their private key.

Patented technology
The technology applied in the SplitKey product is patented as a European patent no. 3529948.


Knowledge and biometrics based authentication and signing solution

SplitKey+ builds on Cybernetica’s 4 and 5-digit PIN knowledge-based solution for authentication and signing.
By combining threshold cryptography and liveness testing with face recognition, SplitKey+ adds a level of security that gives confidence and reduces risk.

Working with our liveness testing partners, we can offer a LoA High for both PIN and biometrics, with the additional option of pattern. Service providers can select which combination and when these methods are used.

Authenticate with PIN and sign with biometrics, or prompt PIN and biometrics for authentication and PIN2 for signing. Any combination of PIN, pattern and biometric based liveness testing can be utilised.

SplitKey CSP

Cybernetica is expanding its SplitKey product line to compliment the emerging European Union Digital Identity Wallet (EUDIW) ecosystem.

  • Cryptographic service provider based on SplitKey

  • For mobile platforms that do not have a suitable hardware-based Trusted Execution Environment or Secure Enclave chip

  • Hardware agnostic

Advanced cryptographic services for digital identity wallet applications

SplitKey was designed in 2016 for the needs of software-based eID means, providing eIDAS1-compliant “high” level authentication and QSCD-level electronic signatures. We used threshold-cryptography-based algorithms and achieved unique security properties for a software-based solution.

Now, we have taken the same idea and developed an advanced, ready-to-integrate software module for wallets, which provides the following security features:

  • Private key generation and signature creation

  • RSA algorithm support, ECDSA/EdDSA and PQC on the roadmap

  • Integration with identity proofing (RA) and X.509 certification (CA)

  • User’s sole control of cryptographic material, PIN verification and clone detection

  • Common Criteria EAL4+ certification ready, aligned with EN 419 241-2 (rQSCD PP)


Cybernetica offers a consulting service for digital identity to advise and analyse the current landscape and provide meaningful input for the journey ahead.

Harnessing the strength of our PhD’s, Research Institute and being one of the original architects of e-Estonia, we have a strong pedigree to assist and guide your digital identity transformation.
