G+D Filia® – cash for the digital age
G+D Filia® is our commitment to supporting central banks, commercial banks, fintechs, merchants, and other players in overcoming the roadblocks to CBDC. Filia® follows a token-based approach and tackles some of the most challenging requirements for a CBDC. The Filia® system consist of eight components so that stakeholders benefit from a modular system.
Embrace innovation and growth
Existing members of the currency cycle play a vital role in G+D’s hybrid-deployment model of a value-based CBDC solution. Here, the creation and issuance of data files that represent monetary value take place in a highly secure offline environment at the central bank, while distribution is carried out by commercial banks or other financial service providers. Payment service providers can integrate Filia® into their own offerings – as part of a larger payment ecosystem – to enable new business models, and to foster growth and innovation in an open system.
Universal accessibility to digital payment
Filia® can be utilized through smartphones, smart cards, smartwatches, and other forms of digital wallets, without the need for a bank account, the disclosure of private data, or consumer fees. It can be used for payments in areas with no power supply or internet connection - even without a mobile network. This helps central banks fulfill their mandate of issuing a digital form of legal tender that can be used independently while guaranteeing widespread benefits for both businesses and the general public.

Security powered by secunet: Filia®’s PKI
With Filia®, central banks can generate digital tokens that represent a value, which can be stored and transferred easily via digital wallets – a truly convenient complement to cash. Convenience must come with security, however. Just as banknotes are protected by haptic, optic, and other security features against counterfeiting, a central bank digital currency (CBDC) must also be secured against fraud and misuse. Germany’s leading cybersecurity company, secunet Security Networks AG, affiliated with the G+D Group, fulfills this function for Filia®.
Protecting digital infrastructures is one of secunet’s missions. From developing the security architecture, to creating the public key infrastructure (PKI) concept, and securing authentication during payment through its own eID PKI suite, secunet has been integral to every step of Filia®’s journey. Its remit extends from preventing duplication and counterfeiting of digital wallets, to consulting on the design of the central ledger of a central bank. Crucially, it has dealt with the security around leaving token-based currency on smart cards, and securing them with cryptography. secunet’s roster of clients includes the German Federal Police, EU border control, and numerous government and corporate clients.
