Central bank digital currency technical guideline
The German Federal Office for Information Security (BSI) published a technical guideline (TR) describing requirements that ensure a high level of IT security for the backend systems that support the operation of a central bank digital currency (CBDC) ecosystem. The CBDC ecosystem consists of the backend systems operated by the central bank, the frontend functionality made available to end users by wallet providers, exchange points, which may be operated by third parties other than the central bank, and, potentially, additional service providers. If implemented, the CBDC ecosystem constitutes a critical infrastructure, and the TR aims to ensure that it is made resilient to a wide range of attacks. In addition to implementing the goal of security-by-design, this TR also considers some privacy aspects.
