Network distribution method and system
This application relates to the field of communications technologies, and discloses a network distribution method and system. A first electronic device sends a first probe request, and a second electronic device sends a first probe response after receiving the first probe request. The first electronic device establishes a first connection to the second device by using temporary networking data in the first probe response. The second electronic device transmits network distribution data of a master access point to the first electronic device through a temporary network of the first connection. The first electronic device and the second device then establishes a second connection through the temporary network in an encrypted manner. Therefore, network security of the first electronic device and the second electronic device is high.
