Title

Possible Network Infrastructure Securely Transferring Data Having Value, such as CBDCs

Abstract

Central Bank Digital Currencies (CBDCs) are planned in many countries (central banks) and implemented in some countries. CBDCs issued as legal tender by central banks must guarantee both security and anonymity. This paper discusses network infrastructure requirements for securely transmitting digital assets having value themselves like CBDCs. For this purpose, a method to implement an infrastructure to securely transmit CBDCs using Public Key Infrastructure (PKI) is discussed.
