METHOD FOR PROCESSING SECURITY OF CARD PAYMENT BY USING MOBILE INTERNET COMMUNICATION NETWORK AND RECORDING MEDIUM

摘要

A method for processing security of card payment by using the mobile Internet network and a recording medium thereof are provided to keep high security between a payment terminal placed in the vulnerable high speed mobile Internet and a VAN(Value Added Network) server when the high speed mobile Internet is used for processing the card payment. A payment terminal generates payment processing data(830). The payment terminal extracts a public key corresponding to a VAN server from a security application module of a payment terminal side and encodes the payment processing data with the public key(835). The payment terminal stores the encoded payment processing data to an upper layer of a mobile Internet protocol stack, and transmits the encoded payment processing data to the mobile Internet network by adding mobile Internet based MAC(Media Access Control) and physical layers to the mobile Internet protocol stack(865). The VAN server receives the Internet protocol stack through the mobile Internet network and recovers the encoded payment processing data. The VAN server extracts a private key from the security application module of a server side and decodes the encoded payment processing data with the private key. The VAN server processes payment by using the decoded payment processing data.
