With use case #09 we intend to connect the PSNC datacenter in Poznań and banking datacenter that provide critical digital banking services for citizens. PSNC site is also main Point Of Presence of PIONIER network (Polish National Research and Education Network), GEANT network and other international PSNC and PIONIER partners. Banking datacenter site is one of the PSNC metro area POZMAN sites. The banking sector relies heavily on advanced, fast digital services delivered to end users and between the bank data centers themselves. Large amounts of confidential data is being sent, backed up and synchronized between various banking institutions and divisions. Digital trading platforms are delay and speed sensitive. The services and communication channels between banking institutions are to be secured with advanced QKD network layer infrastructure. The nodes will be deployed in Poznan between PSNC data centers and data centers that host services for the banking sector. The investigated impact will includemaximum possible key exchange rate, delay introduced for the services and management overhead of QKD network layer, number of interconnected, synchronized and secured by QKD network layer systems/platforms, distance vs key rate vs optical power. It is proposed to investigate also concept of “quantum money” and possible implementation in exemplary transactions.
All these services are to be secured and further enhanced with QKD network layer infrastructure and its impact is to be evaluated. The nodes will be deployed in Poznan between PSNC data centers and banking data centers. These use cases introduce specific requirements for the data security and potential QKD integration. The QKD network services must run on various hardware and software platforms. Impact on services and infrastructure will be investigated. The route have 8 km in distance. A QKD system will be installed along with an encryptor to ensure that network traffic, services, may relay on secure connection and critical messages forwarded to the PIONIER and POZMAN Network Operator Center.
