Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0031] The mobile phone security payment method based on the wireless channel of the present invention sets the mobile phone terminal and the key terminal separately, and the key terminal includes a certificate IC and a microcontroller, and the microcontroller has a built-in transponder and identification information of the key terminal; the low-frequency signal can be sent out by setting the mobile terminal base station chip, the payment process of this method is as follows, see also figure 1 ( figure 1 In the process, only when each step is executed correctly can the next step be executed, and if unsuccessful, the communication will be closed).
[0032] 1) When the mobile phone payment function is activated, the base station chip at the mobile phone terminal immediately sends out low-frequency signals at intervals, and the low-fr...

The invention discloses a mobile phone security payment method and system based on a wireless channel, which includes a mobile phone terminal and a key terminal, and a certificate IC and a microcontroller are arranged on the key terminal, and the certificate IC and the microcontroller are bidirectionally connected. There is a base station chip on the mobile phone side, and a low-frequency antenna and a low-frequency wireless communication module on the key side. The low-frequency antenna is connected to the microcontroller and the certificate IC in two directions through the low-frequency wireless communication module. The base station chip can send out low-frequency signals containing identification information, which can be captured by low-frequency antennas, and the corresponding identification information is stored in the microcontroller. The key end of the present invention obtains energy through low-frequency wireless induction, and transmits corresponding encrypted data at the same time to confirm the data communication link key with the host, and starts the low-frequency or / and high-frequency wireless communication mode to realize the wireless communication between the certificate IC and the host, It is convenient and fast to use, has higher reliability, is difficult to crack physically, and has high security.
Description
technical field [0001] The invention relates to a mobile phone payment method and system, in particular to a mobile phone security payment method based on a wireless channel and a payment system designed based on the method, belonging to the technical field of wireless communication. Background technique [0002] With the continuous development of mobile phone functions, mobile payment, as an emerging payment method, has gradually become popular and accepted by young people. Mobile payment makes it possible for consumers to make on-site real-time, non-contact, and small-amount payments through mobile phones, which better meets consumers' needs for mobile payment. At present, there are mainly three mobile payment implementation schemes: mobile phone-based NFC (Near Field Communication, near field communication) scheme, e-NFc (mobile phone-FISIM card integration) scheme, and SIM Pass (single-chip mobile payment solution) scheme. Compared with the previous two schemes, the SIM...
