Design and implement of the Bitcoin payment system based on IC card

Abstract

IC card with its high security,portability and other virtues has become a most widely used payment tool in the financial field.In order to cope with increasingly wide application of the Bitcoin,this research designs Bitcoin payment system based on the IC card in order to improves its safety and convenience.The master key encryption is used to indirectly encrypt password and account private key,avoiding using simple password to cause the reduced safety of private key encryption.Using hierarchical deterministic address will enhance the anonymity of the IC card account.The uniquely determined transaction signature random number scheme based on the key and message will achieve Bitcoin private key secure storage based on IC card and secure payment of Bitcoin transactions.
