Problems solved by technology
[0006] Furthermore, a shortcoming of current NFC devices is that, for NFC device users, when users transmit data to different NFC receiving devices they contact, they cannot independently choose to transmit data information of different contents, and can only transmit the data information in their NFC modules in the same way. All the data and information of the NFC receiving device cannot be treated differently for different NFC receiving devices. It is not convenient to preserve and protect the specific data information that some NFC receiving devices need to keep secret, and it is difficult to achieve the security protection of data information.

Embodiment Construction
[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0032] Such as figure 1 Shown, the encrypted transmission method of NFC equipment data of the present invention, comprises:
[0033] Step 1. Divide an NFC data message into at least one segment of sub-data to correspond to different NFC receiving devices;
[0034] Step 2, for different NFC receiving devices, respectively adopting different encryption keys to encrypt each section of the sub-data;
[0035] Step 3, sending each of the encryption keys to each NFC receiving device corresponding to each segment of the sub-data;
[0036] Step 4. Send the NFC data information to the NFC receiving device, and the NFC receiving device that has received the NFC data information decrypts its own corresponding sub-data through the received encryption key to ob...

The invention discloses an encryption transmission method and system of NFC (Near Field Communication) device data. The method and the system are characterized by dividing NFC data information into a plurality of sections of subdata, encrypting the plurality of sections of subdata by using different keys, informing different NFC receiving devices of all encrypting keys on account of effects or functions of different subdata, so that the NFC receiving devices can only decrypt corresponding subdata by using the known keys when NFC information of different application environments interact, but cannot decrypt other subdata because the devices do not have the corresponding keys; furthermore, the security of data onformation in an NFC transmitting device can be ensured when NFC communication is carried out between the NFC transmitting device and the NFC receiving devices; the specific data information to be secured by the NFC receiving devices can be protected.
Description
technical field [0001] The invention relates to the field of information security, in particular to a data encryption transmission method and system based on an NFC device. Background technique [0002] With the development of Internet technology, the security of data information is becoming more and more important. Data authentication equipment, such as the hardware digital certificate carrier USB KEY, has the functions of personal identity authentication and data encryption and decryption, and has been widely used in various businesses in the fields of online banking and e-government. [0003] In the prior art, the data authentication device is mainly connected to a personal computer terminal (computer) through a USB interface to complete the data authentication process. However, with the development of the mobile Internet, mobile terminal devices (such as mobile phones, especially smart phones) have gradually been applied to personal office, online banking payment and ot...
