Embodiment Construction

[0033] The content of the present invention will be further described below in conjunction with specific embodiments. It should be noted that in the embodiments described below, the servers are all cloud servers (Elastic Compute Service, ECS). Cloud servers are computing services with elastically scalable processing capabilities, and their management methods are more complex than traditional physical servers. Simple and efficient. Cloud servers can quickly build more stable and secure applications, reduce the difficulty of development and maintenance and overall IT costs, but this cannot be used to limit the scope of protection requested by the claims of the present invention. Other physical servers that can realize the functions of the present invention are included in this within the scope of the invention claims.

[0034] figure 1 A method for encrypting NFC communication is shown, and this embodiment is described from the perspective of NFC (Near Field Communication) equ...

Abstract

The invention provides an NFC encryption method. The method comprises the following steps that first identifying information of an NFC device of the other party is sent to a server; a secret key returned by the server after the matching relation is determined according to the first identifying information is received; the secret key is decrypted through encrypted codes stored in an NFC device of this party to obtain an initial secret key; the initial secret key is used for decrypting data which are sent by the NFC device of the other party and received by the NFC device of this party, or the initial secret key is used for encrypting data sent by the NFC device of this party. According to the NFC encryption method, the whole NFC process is subjected to two-way encryption through the server in combination with the identifying information of the NFC devices, and therefore the problem of insecurity of NFC is effectively solved; the complexity of encryption is improved in a secondary encryption mode, so that NFC is more reliable.

Description

【Technical field】 [0001] The invention relates to the technical field of NFC communication, in particular to an NFC communication encryption method and system. 【Background technique】 [0002] Near Field Communication (NFC) is a short-range high-frequency radio technology that operates at a frequency of 13.56 MHz within a distance of 20 cm. There are three transmission speeds: 106kbps, 212kbps and 424kbps. At present, NFC has become the ISO / IEC IS 18092 international standard, ECMA-340 standard and ETSI TS 102 190 standard. [0003] NFC near field communication technology is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. NFC-enabled devices can exchange data in active or passive mode. In passive mode, the device that initiates NFC communication, also known as the NFC initiating device (master device), provides a radio frequency field (RF-field) throughout the communication process, and it can choose one of ...
