Embodiment 1

[0031] like figure 1 As shown, the embodiment of the present invention provides a method for encrypted communication, including a first communication device having a first NFC module.

[0032] The method comprises the steps of:

[0033] Step S101. Touch the first NFC module to establish NFC communication with the first communication device.

[0034] The method also includes a second communication device with a second NFC module, the second NFC module touches the first NFC module, and through the communication between the second NFC module and the first NFC module, the second communication device and the first communication device Establish NFC communication.

[0035] Step S102, according to the NFC communication, obtain key information required for encrypted communication with the first communication device.

[0036] After the second communication device establishes NFC communication with the first communication device, the second communication device reads the key informat...

Embodiment 2

[0047] like figure 2 As shown, the embodiment of the present invention provides a method for encrypted communication, including a first communication device having a first NFC module.

[0048] The method comprises the steps of:

[0049] Step S101. Touch the first NFC module to establish NFC communication with the first communication device.

[0050] The method also includes a second communication device with a second NFC module, the second NFC module touches the first NFC module, and through the communication between the second NFC module and the first NFC module, the second communication device and the first communication device Establish NFC communication.

[0051] Step S102. According to the NFC communication, key information required for encrypted communication with the first communication device is sent to the first communication device.

[0052] After the second communication device establishes NFC communication with the first communication device, the second communi...

Embodiment 3

[0063] like image 3 As shown, in order to realize the encrypted communication method of the first embodiment above, the embodiment of the present invention also proposes an encrypted communication system, including a first communication device 1 with a first NFC module 11 and a second NFC module 21 The second communication device 2 .

[0064] The second NFC module 21 touches the first NFC module 11 , and according to the NFC communication, the second communication device 2 establishes NFC communication with the first communication device 1 .

[0065] The second NFC module 21 touches the first NFC module 11 , and through the communication between the second NFC module 21 and the first NFC module 11 , the second communication device 2 establishes NFC communication with the first communication device 1 .

[0066] The second communication device 2 acquires key information required for encrypted communication with the first communication device 1 .

[0067] After the second comm...

Abstract

The invention relates to the communication field and particularly relates to a method and system for encrypting communication. The method for encrypting communication comprises steps of contacting with a first NFC module, establishing NFC communication with a first communication device, obtaining cipher key information which is needed in encryption communication with the first communication device according to the NFC communication and establishing encryption communication with the first communication device according to the cipher key information. The method and system for encrypting communication uses NFC to perform short-distance communication to transmit cipher key information and avoids a fact that the cipher key information is captured by a third party during a process of transmitting the cipher key information due to the short distance in order to encrypt communication and effectively protect classified information.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for encrypting communication. Background technique [0002] In the prior art, the encryption communication method between the main control device and the node is as follows: the two first establish non-encrypted communication for communication connection, the main control device sends the key to the node, after the node receives the key, it maintains the original communication type, and communicates with the main control device. control devices for encrypted communication. [0003] Since the communication distance between the main control device and the node is relatively long during encrypted communication, there is a risk of being acquired by a third party when transmitting the key. If the key is obtained by a third party when the key is transmitted, the encrypted communication between the main control device and the node will be deciphered by the third party, and...
