(English Abstract)
PKI Internet banking is used to have users register their public keys with the banking server together with the identity information, and verify the signature for both user and transaction authentications by using the registered public keys. Although the Blockchain-based financial systems such as Bitcoin adopt similar digital signature-based authentication scheme, there is no server that participants can register public keys with because they perform P2P payment transactions. The purpose of this paper is to identify the advantages and disadvantages of the Blockchain-based payment transactions by analyzing the differences between the most common PKI Internet banking and Blockchain payment systems. Based on the analysis, this paper suggests the issues that need to be enhanced from the aspects of architecture and security in order for Blockchain payment transaction systems to be applied universally.
