Embodiment Construction

[0031] 1. One user opens the application program on the mobile terminal and sets it to server mode. At this time, the client application program performs the following operations (such as figure 1 shown):

[0032] a. Generate a WiFi connection key and encrypt it into ciphertext with the encryption program in the software;

[0033] b. Extracting the program identification and the key in ciphertext form to form an SSID number;

[0034] c. Detect whether the system WiFi is turned on, and if it is not turned on, turn on the WiFi module;

[0035] d. Check whether the system WiFi is in the AP working mode. If not, set the WiFi to the AP mode, and set the SSID to the SSID number in step b.

[0036] 2. Client mode The user of the handheld device turns on the client mode, and at this time the corresponding mobile terminal application program performs the following operations (such as figure 2 shown):

[0037] a Check whether the system WiFi is turned on, if not, turn on the WiFi m...

Abstract

The invention belongs to the transmission technical field of wireless network and specifically relates to a method for safely building WiFi connection by SSID in application program. The method uses the open API of mobile operation system, controls and manages WiFi module by program and configures SSID to automatically build WiFi connection by the application program, and exchanges data in safe manner. The method is characterized in that SSID comprises program identifiers and SSID connecting key; the SSID connecting key is encrypted by encrypting program and a process (authorization from user should be acquired after automatically building the WiFi connection, or else, the connection will be removed) is confirmed by the connection to improve the safety.

Description

technical field [0001] The invention belongs to the technical field of wireless network transmission, and in particular relates to a method for securely establishing a WiFi connection by using an SSID in an application program. Background technique [0002] With the development of hardware technology, the application rate of WiFi in mobile terminals continues to increase. At the same time, with the popularization of mobile terminals (tablet computers, smart phones, e-readers, etc.), applications that rely on information exchange between mobile terminals are also increasing. For example, the exchange of multimedia information between mobile terminals, the exchange of electronic business cards between mobile terminals, etc. [0003] At this stage, WiFi-based data exchange between mobile terminals roughly has the following forms: [0004] 1. Commonly connected in a wireless local area network through wireless routing equipment, this method requires each mobile terminal to have...
