Abstract

An automatic wireless network linking method with a security configuration includes: providing an access point with a floating service set identifier and a shared key. The floating service set identifier has a prefix name. Next, a host system is provided to execute a setting and linking application to automatically scan the access point with the prefix name and obtain the floating service set identifier of the access point. Both the access point and the setting and linking application perform an operation process to generate a dynamic key. The dynamic key is converted into a wireless network encryption algorithm. Finally, the host system links to the access point to perform wireless communication, and uses the wireless network encryption algorithm to encrypt and decrypt data. Thereby, the time required for setting up the wireless network platform is reduced.

Claims

1. An automatic wireless network linking method with a security configuration, comprising:

providing an access point with a floating service set identifier and a shared key, wherein the floating service set identifier has a prefix name and a random number identifier, the random number identifier being generated by a random number generator when the access point starts up and is an active variable;

providing a host system to execute a setting and linking application for automatically scanning the access point with the prefix name and obtaining the floating service set identifier and the shared key of the access point, so that the setting and linking application shares the same shared key with the access point;

performing an operation process to operate the floating service set identifier with the shared key to form a dynamic key via both the access point and the setting and linking application, wherein the dynamic key is converted into a wireless network encryption algorithm; and

forming a wireless link between the host system and the access point and using the wireless network encryption algorithm to encrypt and decrypt data.

2. The automatic wireless network linking method with a security configuration as claimed in claim 1, wherein the floating service set identifier further comprises a device name for inputting the name of the access point to form a passive variable;

thereby, the floating service set identifier includes the prefix name, the random number identifier, and the device name, and the generated floating service set identifiers are different from each other due to the active variable and the passive variable.

3. The automatic wireless network linking method with a security configuration as claimed in claim 1, wherein a physical address, a user name, and a password are added into the operation process to be assembled with the floating service set identifier and operate with the shared key to form the dynamic key.

4. The automatic wireless network linking method with a security configuration as claimed in claim 3, wherein the physical address is a physical address of a wireless network interface of the access point.

5. The automatic wireless network linking method with a security configuration as claimed in claim 1, wherein the operation procedure is a message digest-5, a digital encryption standard, an advanced encryption standard, or any other kind of mathematical algorithm.

6. The automatic wireless network linking method with a security configuration as claimed in claim 1, wherein the wireless network encryption algorithm is a wired equivalent privacy (WEP), a Wi-Fi protected access—

pre-shared key, or a Wi-Fi protected access2—

pre-shared key.

7. An automatic wireless network linking device with a security configuration, comprising:

an access point having a floating service set identifier and a shared key, wherein the floating service set identifier has a prefix name and a random number identifier, the random number identifier being generated by a random number generator when the access point starts up and is active variable; and

a host system used for executing a setting and linking application to automatically scan the access point according to the prefix name and obtaining the floating service set identifier and the shared key of the access point;

wherein the setting and linking application and the access point have the same shared key, both the access point and the setting and linking application perform an operation process to operate the floating service set identifier with the shared key to form a dynamic key and convert the dynamic key into a wireless network encryption algorithm;

thereby, the host system links to the access point to perform a wireless communication via the wireless network encryption algorithm.

8. The automatic wireless network linking device with a security configuration as claimed in claim 7, wherein the floating service set identifier further comprises a device name for inputting the name of the access point to form a passive variable;

thereby, the floating service set identifier includes the prefix name, the random number identifier, and the device name, and the generated floating service set identifiers are different from each other due to the active variable and the passive variable.

9. The automatic wireless network linking device with a security configuration as claimed in claim 7, wherein a physical address, a user name, and a password are added into the operation process to be assembled with the floating service set identifier and operate with the shared key to form the dynamic key.
