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

摘要

The present invention relates to a portable card security processing methods,It is using Internet communication networks and system and payment terminal device and passes through a computer-readable record media it is characterized in that one plan of storage for this purpose,The card of a portable internet network used according to the invention for safety of payment processing system,Payment terminal private key is extracted in one predetermined terminal-side digital signal processor is related to production one from the payment process data of security application module(Request data is checked and approved in the payment of profession)'s,Payment process related data(Payment authorization request specializes in data)With a certificate of extraction,It contains VAN server public keys and payment terminal public keys from end edge security application module,Generate a scheduled random secret key and certificate copy,Including digital signal processor and payment terminal public keys payment processing-related data(The data of payment authorization request profession)Encryption and the encryption of random secret key VAN server public keys and encrypted electronic signature and certificate copy include payment terminal public keys payment processing-related data(The data of payment authorization request profession),And the random secret key of increased series connection VAN server public keys encryption,Then light based on the Internet media MAC layer and PHY layers,It arrives portable internet protocol stack,It is stored in the high level of mobile IP storehouse mobile Internet communication network payment terminal of transmission; In PHY layers of removal and based on after the portable consumer of the MAC layer in wireless Internet heaps, one payment terminal transmits, change Mobile Internet Protocol heap to Internet protocol heap, the Internet protocol heap of a change of transmission is to the VAN server portable internet networks for passing through a communication network; Receiving Internet protocol heap to pass through portable internet network,The digital signal processor and payment terminal public key certificate of encryption,A payment process related data,Including(The data of payment authorization request profession),After disclosing transmission with the VAN servers for restoring a random secret key encryption key,VAN server private keys are extracted from the predetermined server side of Secure Application Module,Pass through VAN server private keys,It reads through decoding random secret key,Random secret key,Its digital signal processor and payment terminal public key certificate for being encrypted by decryption,A payment process related data,Including(The data of payment authorization request profession),With the payment process related data of decoding decryption,It is in digital signal processor(Payment authorization request when verifying the validity of an expert data)On,And validity is verified,Payment process related data is decrypted using saying(The data of payment authorization request profession)VAN servers are for executing a scheduled payment process process; It is characterized by comprising a. To which driving is used to handle the attack in e-payment in a communication network vulnerable to safety high speed wireless Internet, has an advantage to keep payment terminal and advanced end-to-end security between the VAN servers for the wireless Internet for being positioned at high speed. ;Movably, internet, safety, book keeping operation,
