Method of using SD information encryption to realize quick SD and AP connection in uncorrelated WIFI environment

Abstract

The invention discloses a method of using SD information encryption to realize quick SD and AP connection in an uncorrelated WIFI environment. A third-party mobile terminal MT is also included. The method comprises steps: the SD virtualizes a pseudo AP; the MT actively scans nearby APs, the pseudo AP is identified through a near-distance wireless identification technology, MAC of the SD is acquired, and the MAC is sent to the AP; the AP uses the MAC to encrypt self device information to form a data flow, and the data are embedded in broadcasting frames to form a broadcasting packet to be sent; after the SD receives the broadcasting packet, the self MAC is used for decryption, the device information of the AP is extracted, correlation with the AP is thus carried out, and quick connection is completed. The third-party mobile terminal MT is delicately used as a medium to acquire the MAC information of the SD, the information thus serves as a key to encrypt the self device information of the AP, the AP can limit a receiving party while actively broadcasting the self device information, an error connection condition during an intelligent networking process can be avoided completely, the operation is accurate and reliable, and the security is high.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for realizing fast connection between SD and AP by using SD information encryption in an unrelated WIFI environment. Background technique [0002] With the continuous rise of the Internet and the increasingly prominent mobile demand, the demand for wireless interconnection is also becoming stronger. Among the existing wireless communication technologies, the bluetooth communication technology has a small coverage area, and the infrared communication technology is greatly affected by the environment, and the effect of penetrating walls is not ideal. Due to its wide application, WIFI communication technology is gradually accepted by enterprises and families. In the traditional standard-based IEEE802.11, the wireless network specification is defined: one wireless point acts as the AP (Access Point) mode, and other wireless points act as the STA (STAtion) mod...

AI Technical Summary

Problems solved by technology

[0003] However, for some special smart devices, such as SD (Smart Devices) without input devices, serial ports, and touch screens, if they want to communicate with APs, the existing technical solutions are helpless.

On the other hand, when users use absolutely safe and reliable SD devices to connect to APs, they hope to obtain a faster and more efficient connection solution than the existing technical solutions, but there is no reasonable, fast and efficient solution in the current market

Moreover, in the networking application of smart home, there may usually be many SDs, which will lead to some false networking situations, but this is not what the designer wants to see, so this is also a problem that needs to be solved
