Embodiment

Below in conjunction with accompanying drawing, the present invention is described in more detail:

The invention provides a kind of configuration network system automatically, it is characterized in that: comprise focus AP, user side;

Concrete configuration process is as follows:

Embodiment:

1, user, for focus AP arranges a password or password of hotspot device default setting, is encrypted this password according to certain algorithm, then the word string of encrypting is connected as SSID with fixing focus prefix.Fixed CP refers to a string character, be used for that identification contains this prefix SSID takes is what cryptographic algorithm, be convenient to the encryption string that terminal recognition decrypts after prefix and automatically connect networking, shape is as " < Fixed CP >< password encryption string > ".

2, user side is not in the case of the network of having preserved all connects, start automatic configuration network function: first search for focus AP, select best one of ambient network signal, if focus AP name is when appointing Fixed CP, to from hotspot name, parse and encrypt string, and then this encryption string is decrypted according to the algorithm of agreement, obtain the password that arranges of this focus AP.

3, the password by SSID and deciphering is from being dynamically connected this focus.

Cryptographic algorithm can ensure the private ownership of network, avoids disabled user to connect.Complicated enciphering and deciphering algorithm is by the fail safe of Strengthens network.Selecting best one of ambient network signal, is to be automatically connected to the similar focus in next door for fear of user side.Focus AP can, by mac address filter is set, can stop the connection from similar user side Client.The MAC Address of user side Client has not setting to user, avoids programming to cheat use mac address filter by MAC Address.

First with reference to figure 1, figure comprises focus AP, user side and internet 8.Focus AP is the router that is not limited to have WIFI function, and wireless user's end is for having the mobile device of WIFI function, by WIFI module (RX 3, TX 9) and antenna (14,13) communicate separately.Focus AP is directly connected by netting twine with internet 8, once user side and focus AP successful connection, the resource on just can access the Internet 8.

It is for generating focus password that the password of focus AP is produced device 4, encryption equipment 5 is for the password generating is encrypted by the algorithm of agreement, AP processor 6 completes the calculating of cryptographic algorithm, and the Fixed CP of the encryption string calculating and agreement is spliced into focus SSID, and this configuration is saved in focus AP memory 7.

User side is started shooting first and is searched network around, and by several character strings before in comparison focus SSID, i.e. Fixed CP, judges whether with the Fixed CP of appointing.If coupling, decoder 12 adds the decipherment algorithm that uses Fixed CP instruction string and decodes being contained in password in SSID.User side processor 10 completes coupling, the parsing of password encryption string and the calculating of decipherment algorithm of Fixed CP.Subsequently, use this Fixed CP to be connected focus AP with password, once successful connection, Fixed CP and password will be saved in user side memory 11.

With reference to figure 2, focus AP generates the whole flow process of SSID with Crypted password.Focus AP mono-opens, focus AP will generate unencrypted password at random or according to hotspot device UUID, then, this password will be encrypted according to the cryptographic algorithm of agreement, again the password of encryption and the Fixed CP of appointing are merged into SSID, preserve this SSID and be connected for user side with password.

Fig. 3 has set forth the process of user side 2 automatic interconnection networks.User side 2 is started shooting, and whether the network that first judgement has been preserved can connect, if can connect, and the network that is certainly dynamically connected and preserves; If can not connect, start automatic configuration feature.Search is focus AP around, filter out the best focus AP of signal, judge whether this focus has fixing prefix, if having an appointment the Fixed CP of reserving, from focus SSID, take out the password string of encrypting, password string according to the algorithm for encryption of Fixed CP instruction is decoded, be connected focus by the password after deciphering with SSID, complete automatic interconnection network, if the Fixed CP of not appointing, can certainly be dynamically connected without network, user can select manual connection.

A simple enciphering and deciphering algorithm, such as this Fixed CP of prefix decipherment algorithm in secret is that 4 16 systems turn 8 10 systems, supposes that Fixed CP is prefix_ so, and the password of setting is that 03120811, SSID is prefix_3c8b.

The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
