Technical field
The present invention relates to information communication and Applied cryptography field more particularly to a kind of one-to-many document distribution method, set
Standby and storage device.
Background technology
Mobile phone has become important internet interface under the mobile Internet epoch, enhancing and people with cell-phone function
Demand raising, mobile phone receive content gradually from simple word to picture, video transition, give mobile Internet life increase
Color is many.But the data traffic generated also increases compared with the epoch of simple text significantly, between high data traffic and flow rate
Contradiction also more highlights.
The various limitations of flow have expedited the emergence of the development of wireless telecommunications, as network technology and cell-phone customer terminal are for wireless
The demand of communication is growing day by day, more and more wireless communication protocols occurs, global WiFi industries has directly been driven to present fast
Surge long situation, and WiFi is in a kind of technology application of the Internet era as short range wireless transmission, with its exclusive advantage
Receive the concern of all circles.But it is limited by equipment coverage area and number of devices, in certain mobile office places or open air
Place does not apply to simultaneously.So how to realize and client is allowed to realize the very fast data in hotspot coverage in the state of no public network
Transfer function, while provide to the security management and controls of data and still an open question instantly.
Have now for no main solution of public network contextual data transmission problem：Mobile phone QQ is passed soon, and eggplant passes soon etc.
Using applications such as USB data transmission and Bluetooth data transfer, mobile phone QQ are passed soon, and eggplant passes soon, it is necessary to receive the side wound of file
WLAN is built, can only realize one-to-one data transmission, it is impossible to realize one-to-many data transmission；USB data transmission, Zhi Neng
It is transmitted between PC and mobile phone terminal or PC and PC, it is impossible to carry out data transmission between mobile phone and mobile phone；Blue-teeth data passes
Defeated, using one-to-one pattern, rate is slow, and efficiency is low.
Therefore, in the environment of no internet is in, but when needing with more people's shared files, according to existing technology,
You need ceaselessly to open connection, and with more people for transmitting being needed to be connect one by one, disconnecting, the operations such as connecting, these are numerous and diverse
Operation bring great inconvenience, and extremely inefficient, in summary various, there is an urgent need for safely and efficiently transmit file at present.

Step 2：Client connects the Wi-Fi hotspot；
Step 3：Using attribute encryption technology, the file that server end calls file manager to send selection adds
It is close, generate attribute private key, and client access control policy is set；
Step 4：Server end obtains the information of all clients, especially IP by accessing server-side database
Then location is distributed attribute private key according to the identity of different clients；
Step 5：Using Socket socket communication technologies, the secure communication mechanism of one-to-many two-way interactive is established, is serviced
The file is transferred to the client in IP lists by device end；
Step 6：Client receives file, and is decrypted according to the attribute private key received, checks file.
Further, in step 1, the Wi-Fi hotspot is that server end obtains WiFi management by WiFiManager
Service, and Wi-Fi hotspot information is created, and reflected by Java and call setting hot spot using WiFiConfiguration.
Further, in step 3, using attribute encryption technology, the server end sets file access permission.
Further, in step 3, encryption attribute realizes that process is：First using an implicit security parameter as input,
Common parameter PK and master key MK is exported, is initialized；Then it is to belong to encrypt message M, common parameter PK and access structure A
Property encryption in SMS4 algorithms input parameter, output encryption message M encrypted ciphertext CT of A；And with common parameter PK and master
Input parameters of the key MK as SMS4 algorithms, output attribute private key SK；Finally with ciphertext CT, common parameter PK and attribute private key
Input parameters of the SK as SMS4 algorithms, if attribute set S meets a kind of one-to-many file distributing of access structure, to ciphertext
It is decrypted；Wherein, access structure A is built-up on the basis of global property set, and ciphertext CT includes access structure A,
SK is the attribute private key of attribute set S.
Further, in step 4, the connection of Wi-Fi hotspot is that the client is opened by WiFiManager
Then the Wi-Fi hotspot information that the server end creates is added and is attached by WiFi.
Further, in step 4, the connection verification process of Wi-Fi hotspot is：Pass through NetworkInterface first
All network interfaces are traversed, the IP address of the client is obtained, obtains HostIP；Then by inquiring with having recorded MAC
The file of location obtains the MAC Address of the client；IP, MAC of the client and remark information are finally transferred to unlatching
The server end of Wi-Fi hotspot, and store in its database.
Further, in step 4, the information of the client includes IP, MAC and remark information of the client.
A kind of storage device, store instruction and data are used to implement a kind of one-to-many document distribution method.
