It is real below in order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention
Example combination attached drawing is applied to Information Authentication method of the invention, system, the composition of storage medium, structure, connection relationship, specific works
Process and working principle, effect and effect are specifically described and are specifically addressed.
Below with the main broadcaster in background technique by server issue lottery information, and it is corresponding connect with server set
Standby actual conditions for receiving the lottery information and being verified are described in detail.
Fig. 1 is the step schematic diagram of the Information Authentication method in the embodiment of the present invention.
As shown in Figure 1, the Information Authentication method of the present embodiment has step S1-S
Step S1 obtains the computing capability grade L of equipment, by following two process:
Step S1-1 acquires the facility information of client.Firstly the need of the facility information of acquisition client, mainly it is to look at
Active client is what equipment to be belonged to, such as mobile device, what mobile phone model is, by model we then
It is known that the computing capability of the equipment, to prepare for the calculation times that subsequent server issues verifying field.So
The better equipment of computing capability, then calculation times identical for verifying field, then the better equipment of ability then calculates more
Fastly.After client logs on live streaming Platform Server, then facility information deviceinfo can be recorded.This implementation
Example is illustrated by taking the acquisition of Apple Inc.'s ios device information as an example, specific as follows:
struct utsname systemInfo；
The structure variable for defining a systemInfo first, for storing the facility information obtained.
Then the facility information of IOS is obtained by the interface function uname of calling system offer, wherein interface uname
It is defined as follows:
uname(struct utsname*name)
It is passed to parameter utsname wherein to obtain the information of equipment.
It is implemented as follows:
Uname(&systemInfo)；
The present embodiment stores the letter got by calling Uname and the incoming variable systemInfo defined before
Breath.Then the information that its corresponding character string systemInfo.machine stores equipment is obtained.
NSString*deviceString=[NSString stringWithCString:systemInfo.machine
encoding:NSUTF8StringEncoding]；
The categorical data of a character string is converted it by the interface stringWithCString of NSString
DeviceString is then ultimately stored in deviceString.
Such as it obtains Iphone6 equipment then, and that deviceString is obtained is iPhone6,1, if equipment is
Iphone7, the then facility information that gets are stored into deviceString, and that obtain is iPhone7, and 1.
So far, the type information of client device is just completed by the step.
Step S1-2, live streaming platform define the level to the computing capability of equipment.Live streaming platform can collect most of set
Standby information, and each facility information is classified according to its calculated performance, then calculated performance it is relatively high equipment it is then fixed
Justice be it is high-grade, calculated performance it is low be then defined as inferior grade, such as can calculated performance to equipment according to 5 grades points
Class, such as ios equipment, iphonex is the equipment that calculated performance is best instantly, then is defined as 5 grades, for
Iphone8 then performance can a poor line, then be defined as 4 grades, 3 grades be then defined as iphone7, iphone6 can then be determined
Justice is 2 grades, for iphone5 and following, is defined as 1 grade.Similarly the equipment of android can also be carried out similarly
Classification.A classification table to ios and android equipment finally so is store in server, corresponding by the table is closed
System, arbitrary equipment can obtain the corresponding computing capability grade L of the equipment.
So far, just completed by the step server equipment is classified and obtained a device signal with
The correspondence table of computing capability grade L.
Step S2 divides M batch to notify multiple equipment in different moments, and the notification information of corresponding each equipment includes pair
The computing capability grade L answered, the batch sequence D for examining field and the notification information relative to earliest first batch.
When main broadcaster starts prize drawing, then server needs the equipment held to all users of direct broadcasting room transmission to announce the winners in a lottery
Message, in order not to cause same time owner to receive barrage prize drawing while sending prize drawing message, then server can be at one
Between notify all users in batches in section, rather than notified simultaneously.
The specific steps notified in batches include:
Selected time T is divided into M parts；
The corresponding all equipment of server is also divided into M parts；
Within first T/M time, the equipment that the notification information is sent to first part of first batch, then according to batch
Secondary sequence is sent to other equipment until being sent.
Specifically in the present embodiment, all users are notified within 1 second total time:
Server can divide room user equally first, and every 200 milliseconds are spaced as one, then 1 second is then
1000 milliseconds, user is divided into 5 equal portions, is identical number if it is 1-4 equal portions, and the 5th deficiency, is also still divided into 5
Part.
User in first 200 milliseconds is not delayed, user receive server announce the winners in a lottery notice message when,
Delay field in message field is 0, if user is notified at second 200 milliseconds, delay field is then
It is 1, similarly if it is what is notified at the 5th 200 milliseconds, delay field is then 4.It can finally lead in 1 second server
Know that all clients room main broadcaster has issued message of announcing the winners in a lottery.And it is opposite that its notification information can be carried in message field
In the batch sequence D of earliest first batch.
Specifically, notifying that the message announced the winners in a lottery is in the present embodiment:
@=2/ type@=lotterystart/rid@=345/timedelay
Such as type@=lotterystart/ mark is to start the message of prize drawing in text message.
@=345 item message field rid identify room number.
@=2 item message field timedelay identify batch sequence D of the prize drawing message relative to earliest first batch,
I.e. the information is in the 3rd 200 milliseconds of notices, and the batch relative to earliest first batch is ordered as 2.
In order to avoid hacker by design code robot or relies on the equipment of function admirable come the prize drawing of brush barrage, service
Device can also issue some data, to improve the safety and randomness of algorithm, server, which issues data, can then accomplish each use
Family is different, and each moment is replaced.
In addition, the present embodiment uses for reference the proof of work algorithm in block chain: in block chain, the life of each new block
Chengdu be have certain workload calculate correctly as a result, who first calculates correct result who then generates new block,
To be awarded.The present invention also verifies client using the algorithm of workload, so that each prize drawing barrage is all
It is the proof for needing to carry out workload, to avoid the script of hacker a large amount of and send the justice of prize drawing and influence prize drawing user
Property, the proof of work of notification information can also adjust according to delay.It is implemented as follows:
A, increase random data in message of announcing the winners in a lottery.
In order to ensure client each time proof of work algorithm safety, prevent it from getting by enumerating
Correctly it is worth, increases a random data in the message of announcing the winners in a lottery that the present embodiment issues each by server, this data is
The character string of 32 bit lengths, and each user can be different random data, each moment also can be it is different with
Machine data, so that client is unable to get the rule of data generation, so that result can not be directly obtained around calculating.
It is implemented as follows:
ServerRandData [32]=rand ()；
Wherein then calling system function rand () generates random number data herein.
The message of announcing the winners in a lottery for wherein starting prize drawing is:
@=2/ type@=lotterystart/rid@=345/timedelay
Then become after then adding random data:
Type@=lotterystart/rid@=345/timedelay@=2/ServerRandData=
ac2536bcac84523697412acdeabdabc123
To increase random data field: ServerRandData=
ac2536bcac84523697412acdeabdabc123。
B, increase device levels data in message of announcing the winners in a lottery.
When client logs on to live streaming Platform Server, current facility information can be reported, server foundation reports
Facility information inquires the grade of the equipment, so that computing capability grade L is handed down to client.These level information then corresponds to
The calculated performance of equipment.Why consider that the computing capability grade of equipment is that fairness, better equipment calculate more in order to balance
Fastly, so server issues different difficulty in computation according to device levels.
Type@=lotterystart/rid@=345/timedelay@=2/ServerRandData=
@=2/ ac2536bcac84523697412acdeabdabc123/level
To increase@=2 computing capability grade L:level of equipment.
So far, just completed by the step server client prize drawing message in carry out at times notify client
End, and increase interval field i.e. notification information of delay in the message relative to the batch sequence D of earliest first batch, inspection
Test the computing capability grade L of field and equipment.
Step S3, equipment and server, which are established, to be communicated and generates shared key.
Fig. 2 is that the detailed process schematic diagram for communicating and generating shared key is established in the embodiment of the present invention.
Establishing communication and generating the process of shared key includes following sub-step:
S3-1, when equipment logs on to server, server generates a pair of of public key and private according to the user information of the equipment
Key.
When client logs on to live streaming platform, Platform Server is broadcast live at this time then can generate one according to the user information
To code key.Simultaneously in order to which the key information for ensureing each user is inconsistent, improve the threshold cracked, then by the account of user and
Random data is as private key information, to ensure that each private key for user is inconsistent.The present embodiment then uses asymmetric rsa encryption
Algorithm next life public key and private key in a pair.Generating random number can be used in specific then private key, and public key then calls RSA cryptographic algorithms
Corresponding public key can be generated in interface function, and private key and public key are the relationships uniquely matched, and actual operating process includes:
A generates random data
Randdata=rand ()；
One section of random data Randdata is generated by calling system function rand.
B is according to room number and generating random number its Md5 value as private key
ClientPrivatekey=Md5.Create (UserId+TimeStamp+randdata)
By call the interface Md5.Create of Md5 function come to User ID and random data and current time stamp information with
And random number is spliced together and calculates its Md5 value, to obtain private key data.
C calculates public key
ClientPublickey=RSA.CreatePair (ClientPrivatekey)；
Public key then calls the generation of RSA to match key interface RSA.CreatePair to generate.
To which final server then generates a pair of of public key and private key information.
So far, just completed by the step the user that live streaming Platform Server is each login generate a pair of of private key and
Public key information.
S3-2, when equipment logs on to server, equipment generates one according to the timestamp of field and login time is examined
To public key and private key.
When client logs on to live streaming Platform Server, server client can generate a pair of of public, private key letter thus
Breath, while client also oneself can generate a set of public, private key information, client then will use random data and timestamp next life
At private key, to ensure that different clients are different private key and public key as far as possible.Actual operating process includes:
A generates random data
Randdata=rand ()；
One section of random data Randdata is generated by calling system function rand.
B timestamp and generating random number its Md5 value are as private key
The interface that ServerPrivatekey=Md5.Create (Randdata+timestamp) passes through calling Md5 function
Md5.Create calculates its Md5 value to be spliced together to random data and current time stamp information, to obtain private key number
According to.
C calculates public key
ServerPublickey=RSA.CreatePair (ServerPrivatekey)；
Public key then calls the generation of RSA to match key interface RSA.CreatePair to generate.
To which End-Customer end then generates a pair of of public key and private key information.
After receiving the public key information that live streaming Platform Server issues at this time, then it is flat the public key information of oneself to be sent to live streaming
Platform server.
So far, it is achieved that client generates a pair of of public key and private key information by the step.
S3-3, server and each equipment intercourse public key and realize that key is shared and establishes communication.
Platform Server is broadcast live and client exchanges respective public key information, to generate a shared code key, and visitor
The shared code key that family end and server generate is the same value.Actual operating process includes:
A exchanges public key
Platform Server is broadcast live, the public key ServerPublickey of server is sent to client.Client by oneself
Public key ClientPublickey be sent to live streaming Platform Server.
B is broadcast live platform and generates shared code key
Use ShareKey=RSA.CreateShareKey (ClientPublickey, ServerPrivatekey) generation
Code is realized；
C client generates shared code key.
Use ShareKey=RSA.CreateShareKey (ServerPublickey, ClientPrivatekey) generation
Code is realized；
It with the value for 2 ShareKey of shared key that client generates is consistent to which the shared key of platform generation be broadcast live
's.
By these three sub-steps of S3-1 to S3-3, equipment and server are established and communicate and generate shared key.
Step S4, the equipment receives the corresponding notification information, and the inspection field is input to preset calculation
Calculated result is calculated in method, enters when the number N of the predetermined value in calculated result meets N=L+M-D in next step.
Client receives the notification information of corresponding lottery information, and calculates verifying field.
When client receive server issue start prize drawing announce the winners in a lottery message after, need first to calculate verifying field, lead to
Certain algorithm is crossed, the message drawn a lottery could be sent after being verified field.The algorithm of proof of work is then used herein.
The present embodiment is to need to calculate HASH value to random data, while calculating HASH after client receives random data
The data that client can generate one 32 when value, which are spliced together, to be calculated, and needs to ensure the HASH result of calculating
In, start and must satisfy the requirement of server for 0 number N, then 0 number is more, then the calculative time can also get over
It is more.
If the requirements are not met, then client can change 32 data generated again, until meeting the requirements.
So in the message that starts to draw a lottery that server issues, the grade of equipment the high, and the performance calculated is better, and client then needs
The number N that the beginning of corresponding calculating is 0 is more, while when message of announcing the winners in a lottery issues, the time of delay is longer, then beginning is 0
It is fewer to calculate number.
Calculate the calculation formula that client (equipment connecting with server) needs to calculate the number N that HASH result is 0
Are as follows:
N=L+M-D；
Wherein L is the computing capability grade of equipment, and higher grade, and the number that required calculating hash value is 0 is more.
Wherein M is the number that the total time T sent in batches that will be selected is divided into.
D is that the notification information sorts relative to the batch of earliest first batch, and embodiment is the lottery information issued
Delay is divided into M grade, is delayed more, then its calculative 0 number is fewer.
The method operation that scheduled hash is calculated is as follows:
Clientdata=00000000000000000000000000000001
Hashresult=Md5.Create (Clientdata+ServerRandData)；
After obtaining calculated result, whether has to the beginning of result judgement hashresult and meet the number that HASH result is 0
N, if conditions are not met, then need to convert Clientdata, the algorithm of transformation be carry out it is incremental.
Clientdata=00000000000000000000000000000002
Hashresult=Md5.Create (Clientdata+ServerRandData)；
This determines again, if meet, and so on, until the result of calculating meets the number of N.
Fig. 3 is the detailed process schematic diagram that the present invention is Information Authentication step in embodiment.
Step S5, by calculated result using shared key encrypting and transmitting to server, and by the server authentication calculating
As a result whether match with pre-stored result, be verified if matching.Specifically include sub-step below:
Calculated result is generated prize drawing message by step S5-1, client device.
The Hashresult result for needing to increase Clientdata and calculating in the prize drawing message field of client occurs
To server, server can then verify the whether correct of client calculating.
The lottery information of transmission are as follows:
Type@=lottery/rid@=345/Clientdata@=
00000000000000000000000000000002/ashresult@=/
00ac23d6a5c14e2a3acbe32125478993/ wherein, ashresult@=/
00ac23d6a5c14e2a3acbe32125478993/ is to calculate result.
Step S5-2, client are reported to server after being encrypted lottery information.
Client is reported to server after generating lottery information again after encrypting data using sharekey, and
It will use safer Encryption Algorithm herein, in above-mentioned these three steps of step S3-1 to S3-3, equipment and server
It establishes and communicates and generate shared key sharekey.
Client is reported to server after being encrypted the message of prize drawing, this reports process real by code below
It is existing:
EncryptData=Aes.Ecnrypt (" type@=lottery/rid@=345/Clientdata@=
00000000000000000000000000000002/Hashresult@=/
00ac23d6a5c14e2a3acbe32125478993/",sharekey)；
The data wherein encrypted are then the message of announcing the winners in a lottery that client reports, wherein the key encrypted is then being total to using negotiation
Enjoy sharekey.
So far, client is just completed by the step report encrypted result.
Step S5-3, server authentication client calculated result.
After server receives the calculated result that client reports, then result can be decrypted and be verified, verify client
Whether the calculated result at end is correct, if can correctly participate in prize drawing, otherwise server is considered an illegal request
To brush prize drawing.Specific verification process is as follows:
The notification information received from equipment is decrypted using public keys by step S5-3-1.Server is to data
It is decrypted, is completed using following code:
Data=Aes.decrypt (EncryptData, sharekey).
Step S5-3-2 is checked whether there is from the data that decryption obtains and is examined field and calculated result, if without if
Determine the data be it is invalid, verifying cannot be passed through, if any, enter in next step.Particularly as being server from decryption
It has seen whether there is Clientdata and Hashresult in obtained data data, has been considered illegal if not, verified
Not pass through.
Step S5-3-3 further judges the inspection field and whether corresponding with the server equipment of issuing of calculated result
Field, calculated result is examined to match, if matching, is verified, otherwise cannot pass through verifying.
Server will record the random data issued to each client, then server also has recorded client quilt simultaneously
Batch sequence D of the delay delay i.e. notification information of the i.e. lottery information of information of issuing a notice relative to earliest first batch,
To which server can calculate in the hash result of client 0 number N according to N=L+M-D, then server then judges
Whether 0 number N meets the requirements in Hashresult, is considered illegal if being unsatisfactory for, if it is satisfied, further clothes
Whether the calculated result that business device can calculate client is correct.
Serverhashresult=md5.create (Clientdata+ServerRandData)；
Judge what the pre-stored result serverhashresult of server and client were reported by the above code
Whether hashresult is consistent, and explanation is illegal if inconsistent.
From algorithm as can be seen that this paper server only needs once to be calculated, and client is wanted to calculate satisfaction
0 number asked needs constantly to convert Clientdata and repeatedly calculates hashresult.
So far, it includes to calculate what is made according to lottery information to client that server is just completed by the step
As a result request lottery information carries out the power process of legitimate verification judgement.
