Analysis Of Apple Pay Payment Security

With the fast developing of the society,contactless payment are popular among people.Due to the contactless payment,people save a lot of time when shopping.However,this new technique doesn't require password when paying but only dip the card near the shop reader.Therefore,the security of this new payment is heated debate among people.The existing contactless payment detection system has some problems.For example,it is not fit for Apple Pay,and the results of decoding is not accurate.Also the cardholder has to depart from his card during testing.In order to solve those problems,a new testing system was proposed pointing to Apple Pay.This new testing system is composed of four modules:tag discovered module,data processing module,communication module,and instruction processing module.Tag discovered module and communication module take advantage of NFC technology and work as server,talking to data processing module in a secure way.Data processing and instruction processing modules can solve the risks on departing the card from cardholder.Meanwhile,the data processing module modified the tag decoding algorithm and instruction processing module corrected EMV transaction payment protocol.Finally,this Apple Pay detection system was implemented.The collection of data during the Apple Pay transaction was successfully compared with the data for EMV contactless payment cards.We analyzed the security between these two popular payment methods.The results shows that Apple Pay can reduce the risk for Relay attack and the communication time is set for short.Also it took advantage of tokenization technology.However,it exposed its vulnerability on the lack of checking invalid transaction requests.
