Description
Technical Field
The invention relates to a method, in particular to a method for realizing pairing of a power modem through internet access communication.
Background
The modem network is generally used by two or more devices in a networking way. Because signals are transmitted on a power line, the power line belongs to an open network, and the problem of safety easily occurs in non-encrypted transmission. The solution is to pair the devices with each other, the paired devices are in the same private network, know the encryption and decryption modes with each other, and the information can be transmitted safely through encryption. The only basis for judging whether two devices are in the same private network is whether the two devices have the same network identification number nmk (network multimedia key). Pairing is traditionally accomplished using a key press to trigger. When a new device is to join the network, the user needs to respectively press pairing keys on the device which has joined the network and the device which is to join the network to realize pairing. The pairing process is as follows: firstly, a pair of electric cat devices to be paired is powered on and started, and when one electric cat (numbered A) presses a pairing button, the electric cat device sends a string of signals with fixed identification codes through a power line, and the string of signals lasts for a certain time. If other power cats (number B) on the power line network also press the pairing button during the duration, the two power cats complete the handshake pairing through a series of handshake protocols. The two devices have their own NMK before pairing, and as a result of pairing, they negotiate the same NMK. When a third power modem needs to join the private network, the pairing process is the same.
The existing pairing method has the following disadvantages
1. The safety is not high enough, after the power cat A presses the pairing button, other power cats can have a period of validity for pairing with the power cat A, and if other people (such as neighbors) nearby have intentionally or unintentionally pressed the pairing button just within the period of validity, the neighbor power cat device and the power cat A can form a private network. This can lead to a risk of data leakage.
2. Due to the particularity of the power line network, the power line network approaches an open network within a limited spatial distance. In factory production, since many devices are in the same power line network, crosstalk is easily caused by the pairing process in the production process. Specifically, when power cats a1 and B1 are pairing, power cats a2 and B2 may also be pairing. The production is intended to pair a1 and B1, a2 and B2, but a1\ B1 and a2\ B2 are not in the same private network, but because on the same production line, it is easy to generate a situation where a1 and a2 or B2 are paired together, the final production line has to have the pairing process implemented serially. The pairing of A1 and B1, and then the pairing of A2 and B2 cannot be performed simultaneously, resulting in low production efficiency.
When the power cats A1 and B1 are successfully paired, and A2 and B2 are successfully paired, the two private networks are not mixed together in production line. The production line workers are also difficult to judge whether the true pairing is correct or not, and can only check through means such as equipment management webpage checking and the like, so that the production efficiency is low, and the error probability is increased.
