Method and system for networking

A method for networking, performed by a router, comprising:

• performing communication detecting by a NFC sensing device in the router;
• and
• in response to detecting that a terminal enters an effective communication range of the NFC sensing device, interacting with the terminal via the NFC sensing device, so that the router or the terminal obtains key information, wherein the key information is configured for networking the router and another router;
• wherein the method further comprises:
• encrypting networking information based on the key information;
• broadcasting the encrypted networking information;
• in response to receiving a networking request sent by the another router, determining whether key information included in the networking request passes verification;
• and
• in response to determining the key information included in the networking request passes verification, performing networking connection to the another router, wherein the networking request is triggered in response that the networking information is successfully decrypted by the another router based on the key information.

A system for networking, comprising:

• a first router with a first NFC sensing device, wherein the first NFC sensing device is configured to sense whether a terminal enters a first effective communication range of the first NFC sensing device;
• a second router with a second NFC sensing device, wherein the second NFC sensing device is configured to sense whether the terminal enters a second effective communication range of the second NFC sensing device;
• the terminal, configured to in response to entering the first effective communication range, interact with the first NFC sensing device, so that the first router or the terminal obtains key information;
• and in response to entering the second effective communication range, writing the key information into the second NFC sensing device;
• wherein the first router and the second router are networked by using the key information;
• wherein the first router is configured to:
• encrypt networking information based on the key information;
• broadcast the encrypted networking information;
• in response to receiving a networking request sent by the second router, determine whether key information included in the networking request passes verification;
• and
• in response to determining the key information included in the networking request passes verification, perform networking connection to the second router, wherein the networking request is triggered in response that the networking information is successfully decrypted by the second router based on the key information.
