Embodiment
The embodiment of the present invention is described in more detail below in conjunction with schematic diagram.According to description below and
Claims, advantages and features of the invention will become apparent from.It should be noted that accompanying drawing is using very simplified form and
Using non-accurately ratio, only for the purpose of facilitating and clarifying the purpose of the embodiments of the invention.
The embodiments of the invention provide a kind of storage method of wifi passwords, according to the title of a wifi hotspot and described
The user cipher of wifi hotspot generates a Crypted password, and the Crypted password is stored in a storage medium.
Specifically, for wifi wpa-psk authentication modes or wpa2-psk authentication modes, the Crypted password
For a pairing master key (PMK, Pairwise Master Key), the Crypted password is stored in the storage medium, i.e.,
PMK is stored in the storage medium.Wherein, wpa is Wi-Fi Protected Access abbreviation, and it is wireless for protection
The system of computer network (Wi-Fi) safety, there is two standards of WPA and WPA2.Psk is Pre-shared Key abbreviation, and it is released
Justice is wildcard.
Further, the PMK is is generated using hash principles according to the title and user cipher of the wifi hotspot
, it is the user cipher that counter can not release the wifi hotspot according to the PMK, there is irreversibility.Obtained that is, working as
The storage medium access limit other people obtain be stored in the PMK in the storage medium when, being can not basis
The PMK is counter release the wifi hotspot be used for password, i.e., can not obtain the user cipher of the wifi hotspot, improve
The security of the user cipher of wifi passwords.
Further, applicants have found that, currently, for wifi wpa-psk authentication modes or wpa2-psk
For authentication mode, when with the wifi hotspot establish connection during, be first from storage medium read storage
The user cipher of wifi hotspot, a PMK is then generated according to the title of wifi hotspot and user cipher, generated further according to the PKM
Other required keys are connected with the wifi hotspot, so as to realize the connection between the wifi hotspot.And above-mentioned
During, it is most according to PMK described in the title dynamic generation of the user cipher and wifi hotspot that are stored in the storage medium
Time-consuming, in Android platform, take around 60 milliseconds or so.
When wifi is during opening, the title and user cipher of the wifi hotspot that can be stored before dynamically be given birth to
Into PMK, if the wifi hotspot quantity stored before is more, it is necessary to which the PMK calculated quantity can also increase, so as to cause
Wifi toggle speed greatly extends.For example, it is 10 to add the wifi hotspot stored before, then need to calculate 10 PMK,
The time needed is about 600 milliseconds, and Consumer's Experience is bad.
And in embodiments of the present invention, due to storing inherently PMK on said storage, then be described
During wifi hotspot establishes connection, it is only necessary to the title with the wifi hotspot of storage is read from the storage medium
Corresponding PMK, then directly established and connected with the wifi hotspot according to the PMK.
A kind of wifi connection methods are provided in embodiments of the present invention, as shown in figure, start to be connected to one when just
During the wifi hotspot not connected before individual, comprise the following steps that.
Step S11：Input the user cipher of the wifi hotspot.
For wifi hotspot that is searching but not connecting, the user cipher of the wifi hotspot is inputted first.
Step S12：One Crypted password is generated according to the title of the wifi hotspot and user cipher, and the encryption is close
Code is stored in a storage medium.
Step S13：Established and connected according to the Crypted password and the wifi hotspot.
The Crypted password, the encryption are generated according to the title and user cipher of the wifi hotspot using hash principles
Password is PMK, and the PMK is stored in the storage medium, is then directly established according to the PMK with the wifi hotspot
Connection.
When the Crypted password is obtained with other AESs, rather than, it is necessary to first enter to the Crypted password during PMK
Row decoding, to obtain the user cipher of the wifi hotspot, then using hash principles according to the title of the wifi hotspot and
User cipher generation PMK after decryption, establishes further according to the PMK and the wifi hotspot and connects.
In this method, store on said storage be not plaintext version user cipher, it is but encrypted
Crypted password, when other people of the acquisition storage medium access limit are obtaining encrypted Crypted password, it can not also obtain
The user cipher of the wifi hotspot is obtained, improves the security of wifi passwords.
The embodiment of the present invention additionally provides a kind of wifi connection methods, has been connected before needing to reconnect
During wifi hotspot, as shown in Fig. 2 comprising the following steps.
Step S21：Read wifi configuration files.
Step S22：Wifi hotspot is obtained from the wifi configuration files.
Step S23：Crypted password corresponding with the title of the wifi hotspot is read from a storage medium.
The Crypted password is the PMK generated using hash principles according to the title and user cipher of the wifi hotspot.
Step S24：Established and connected according to the Crypted password and the wifi hotspot.
Directly established and connected with the wifi hotspot according to the PMK, without the title according to wifi hotspot and user
Cryptographic calculations obtain PMK, when the number of the wifi hotspot stored before is more, also can directly using be stored in it is described storage be situated between
The PMK of each wifi hotspot in matter is directly established with corresponding wifi hotspot and connected, and greatly reduces the time of wifi connections,
Improve Consumer's Experience.
Further, the embodiment of the present invention additionally provides a kind of wifi attachment means, as shown in figure 3, including：One input module
101st, a computing module 102, a memory module 103 and a connection establishment module 104；Wherein, the input module 101 is used for
Input the user cipher of a wifi hotspot；The computing module 102 is used for title and user cipher according to the wifi hotspot
Generate a Crypted password；The memory module 103 is a storage medium, for storing the Crypted password；The connection is established
Module 104, which is used to be established according to the Crypted password and the wifi hotspot, to be connected.
The Crypted password is the PMK generated using hash principles, and the connection establishment module can be direct according to the PMK
Establish and connect with the wifi hotspot.
In embodiments of the present invention, the storage medium includes but is not limited to a FLASH flash memories.
To sum up, in the storage method of wifi passwords provided in an embodiment of the present invention, wifi connection methods and device, according to
The user cipher of the title of one wifi hotspot and the wifi hotspot generates a Crypted password, and the Crypted password is stored in
In one storage medium.Obtain the read-write power of the storage medium other people after the Crypted password is obtained, can not also obtain
The user cipher of the wifi hotspot, improve the security of the password of wifi hotspot.Further, can be close according to the encryption
Code is directly established with the wifi hotspot and connected, and during wifi connections, reduces title and use according to wifi hotspot
The process of Crypted password described in the cryptographic calculations of family, the time that connection is established with the wifi hotspot is reduced, improve wifi companies
The speed connect, and then improve Consumer's Experience.
The preferred embodiments of the present invention are above are only, any restrictions effect is not played to the present invention.Belonging to any
Those skilled in the art, in the range of technical scheme is not departed from, to the invention discloses technical scheme and
Technology contents make the variation such as any type of equivalent substitution or modification, belong to the content without departing from technical scheme, still
Belong within protection scope of the present invention.
