Specific embodiment
The embodiment of the present application provides a kind of believable method of verifying client and relevant apparatus, for increasing live streaming platform
The verification efficiency of server, and the load pressure of live streaming Platform Server is effectively relieved.
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, those skilled in the art's every other implementation obtained without making creative work
Example, shall fall in the protection scope of this application.
Referring to Fig. 1, for the flow chart of the possible verifying believable method of client of one kind provided by the embodiments of the present application,
It specifically includes:
101, Platform Server is broadcast live and client negotiates indentification protocol；
It is understood that needing each client to live streaming platform all to carry out asymmetric calculation in the embodiment of the present application
The verifying of method, in practical application, client specifically includes H5 client, Android, IOS, pc client, therefore for convenient for straight
It broadcasts Platform Server to verify different clients, needs to be identified the type of client in indentification protocol, i.e., it is different
Client type its corresponding ident value must be different.It specifically, can be by creating enumerated variable in the embodiment of the present application
It enumerates all client types, is accomplished by
Enum eClientType{
EClientType_H5=0,
EClientType_Android=1,
EClientType_Ios=2,
EClientType_PC=3,
}
That is, being then the client type of h5 when the value of eClientType is 0；When the value of eClientType is 1, it is then
The client type of Android；It is then the client type of IOS when the value of eClientType is 2；The value of eClientType
It is then the client type of PC when being 3.It should be noted that in practical application, identify the type of client mode have it is more
Kind, uint32_t type (32 integers) can be used for example to indicate the type of client, or by letter with
Number in conjunction with mode identify the type etc. of client, specifically herein without limitation.
It is understood that the verifying language for the client that different platforms is taken is different, i.e., each platform
Conversed analysis cost for hacker is different, for example, for H5 then relative to hacker for can be easier, for PC and
Android then can be more complex, then hacker deliberately distorts client type parameter and more simple around use in order to prevent
Verification algorithm, for example, client type is deliberately passed to parameter from legal 1 setting using the client of Android by hacker
It is 0, i.e. eClientType=0, so that the client that live streaming Platform Server is currently a h5 is cheated, so that verification algorithm
It is more easily reverse and crack.In view of this, in the embodiment of the present application, quotient's indentification protocol of live streaming Platform Server and client association
In then need in addition it is independent increase a client type hiding field.Specifically, one is increased in indentification protocol
The hiding field uint32_t encryptType of encryption passes through block encryption algorithm (tiny in a kind of possible embodiment
Encryption algorithm, TEA) original client type is encrypted, specific function representation is as follows:
EncryptType=Tea.encrypt (type, KEY)；
Wherein Tea.encrypt is used to indicate the encryption interface of TEA algorithm；Type is for indicating original client class
Type；KEY is used for the key for indicating to use when encryption, wherein live streaming Platform Server and client negotiate to use same key
It is encrypted and decrypted, encryptType is for indicating encrypted client type.Therefore client can be by original type
It is contained in indentification protocol with encrypted encryptType and is all reported to live streaming Platform Server together.
Therefore, in the embodiment of the present application, live streaming Platform Server and client negotiate indentification protocol, so that live streaming platform
Server verifies true client type according to the indentification protocol, and then determines that whether preliminary the client is credible.Specifically,
In the embodiment of the present application, indentification protocol can specifically include following information:
Type@=VerifyReq/client@=type2/data@=encryptType
Wherein, type@=VerifyReq is for indicating that the information is indentification protocol；Client@=type is for indicating former
The client type of beginning；Data@=encryptType is for indicating encrypted client type.
Therefore Platform Server is broadcast live after the indentification protocol for receiving client transmission, can according to type and
EncryptType 2 verifies whether client is forged.Accordingly, live streaming Platform Server by TEA enciphering and deciphering algorithm into
Row decryption, specific implementation function are as follows:
Type2=Tea.decrypt (encryptType, KEY)；
Wherein, encryptType is for indicating encrypted client type；KEY is for indicating live streaming Platform Server
The key used when the encryption and decryption negotiated with client；Type2 is used to indicate the client type after decryption.It is after decryption, then right
It is whether more consistent with the value of type than type2, it is verified if consistent, illustrates that client has carried out puppet if inconsistent
It makes, so that Platform Server is broadcast live can go out the client that client is a forgery with Direct Recognition.
Optionally, in practical application, as subsequent continuous iteration updates, algorithm can be updated, with patching bugs
And improve the safety of algorithm.And for the client of mobile terminal, since some users do not timely update, so in the presence of
The case where early version and new version client exist simultaneously, then live streaming Platform Server then needs the different editions to client
Do compatible processing.Therefore in the embodiment of the present application, a version number field can also be increased in indentification protocol, so that live streaming is flat
Platform server can determine the corresponding indentification protocol version of client according to the version number field.In practical application, it can be used
32 integer variables of one uint32_t indicate version number that indentification protocol uses, such as Uint32_t nVersion
=1 indicates first version, and version number 1, nVersion=2 is defined if subsequent upgrade version indicates second version.
Specifically, indentification protocol can specifically include following information in the embodiment of the present application:
Type@=VerifyReq/version@=nVersion/；
Wherein, type@=VerifyReq is for indicating that the information is indentification protocol；Version@=nVersion is used for
Indicate the corresponding indentification protocol version of client.
Therefore, hacker is verified by distorting new client using old indentification protocol in order to prevent, and live streaming is flat
The table that a client release corresponds to agreement can be generated in platform server, corresponding so as to inquire each client release
The version of indentification protocol illustrates to be tampered if mismatching, and directly assert that client is an illegal client.Tool
Body is accomplished by using the map container of normal data library template (standard template library, STL) and stores visitor
The corresponding relationship of family end type, client release and indentification protocol version specifically defines a map array to distinguish difference
Client type if any 4 kinds of clients, then define Map wherein there is several client types then to define corresponding array size
<int, int>mapVer [4], wherein mapVer [0] is used to store the information of client H5, and mapVer [1] is for storing client
The information of Android is held, mapVer [2] is used to store the information of client IOS, and mapVer [3] is for storing client rs PC
Information.In order to allow live streaming Platform Server to determine the client release and each client release pair of each client publication
The indentification protocol version answered, therefore such configuration information, specific function table can be initialized when Platform Server starting is broadcast live
Up to can be such that
mapVer[int].insert(pair<int,int>(x,y))；
Wherein mapVer [int] is used to indicate the type of client, and x is used to indicate the version number of client, and y is for indicating
Corresponding indentification protocol version number, for ease of understanding, below will for example, for example, mapVer [1] .insert (pair <
int,int>(12,1))；For indicating the client type of one Android of insertion, wherein the client of corresponding Android
Version is 12, and corresponding indentification protocol version is 1；Similar, mapVer [2] .insert (pair<int, int>(13,
2))；For indicating the client type of one IOS of insertion, the client release of corresponding IOS is 13, corresponding verifying
Protocol version is 2.It is understood that if subsequent also add other kinds of client or client publication new version, it can
To increase client and the corresponding version number of agreement referring to similar mode.
Therefore, when reporting client current authentication protocol version in indentification protocol when client, platform service is broadcast live
Device then can inquiring client terminal reported data it is whether legal, specifically, live streaming Platform Server judged by writing an interface
The legitimacy of client reported data, for example, Boo CheckVerifyVersion (uint32_t type, uint32_t
appver,uint32_tver)；Wherein, CheckVerifyVersion is used for the judgement interface for indicating to write；uint32_t
Type is for indicating corresponding client type；Uint32_t appver is used to indicate the version number of client；uint32_t
Ver is for indicating the indentification protocol version number that client reports.If judging the indentification protocol version that interface judges that client reports
When number indentification protocol corresponding with the version number of the client type stored and client in map container version number's difference, then say
Bright client is forged, so that Platform Server is broadcast live can go out the client that client is a forgery with Direct Recognition.
To sum up live streaming Platform Server determines the content in indentification protocol by negotiating indentification protocol with client, can be with
Whether preliminary identification client is believable client.
102, live streaming Platform Server sends verifying instruction to client；
In order to further verify the confidence level of client, in the embodiment of the present application, live streaming Platform Server also passes through verifying
The calculation power probe value of client verifies whether client is credible, i.e., live streaming Platform Server can be set according to the calculation power of client
It counts different topics and is issued to client and calculated.It, can be to the problem that live streaming Platform Server issues for client
It carries out that calculated result is calculated and is reported to live streaming Platform Server.It is to be understood that platform is broadcast live in the embodiment of the present application
All topics that server issues all are that the data of the position M issued to live streaming Platform Server encrypt, and obtain encrypted result
Or one M encrypted result data, i.e. calculated result.2 arts are devised in complexity the embodiment of the present application of topic
Language, one is anchor, and one is drift.In the calculated result for the position M that wherein meaning of anchor refers to, designated position be must satisfy directly
Broadcast the numerical requirements of Platform Server.Such as length is in 32 calculated results for being, it is then the definition of anchor that the 1st, which must be 3,.
And the definition floated is then that must satisfy 4 this numerical value in M calculated result to occur, and does not need to specify special position.By
It is many in the complexity that the complexity of anchor is apparently higher than drift, at the same in order to enhance the difficulty in computation of verification result can specify it is multiple
Anchor, and carry out subtle adjustment then if necessary and drift can be used to carry out, therefore can have more by using such mode
The big ranged space determines that live streaming Platform Server issues the complexity of topic.For ease of understanding, the topic for simple difficulty 1 of illustrating
Mesh is as follows: a data must be 5 in the calculated result at live streaming Platform Server given client end；The topic of difficulty 2 is as follows:
It must be 5 that a data in the calculated result at Platform Server given client end, which is broadcast live, and must have a number in result
Word is 4；More more highly difficult topic then can be such that first in the calculated result at live streaming Platform Server given client end
It must be 9 that position data, which must be the 5, and the 2nd bit value,.Same live streaming Platform Server also can specify the number of multiple drifts
According to.Therefore in the embodiment of the present application, the topic of various difficulty can be designed, and drift can be used to finely tune difficulty in topic
Degree.
Therefore live streaming Platform Server sends verifying instruction to client, wherein verifying instruction is used to indicate client generation
Length is the verifying requirement that the calculated result of M need to meet, and verifying instruction includes the live streaming Platform Server that length is (M-N)
Current time stamp, random data of the length for N, the location information of anchor point, the numerical value P of anchor point float numerical value Q a little, wherein anchor point
To be P in the value of the specified location of calculated result, designated position is the location information of anchor point, and drift point is to wrap in calculated result
Q is included, and M is greater than N.For ease of understanding, in the embodiment of the present application, live streaming Platform Server sends the tool of verifying instruction to client
The realization of body function can be such that
Type@=VerifyReq/Timestamp@=1540132018/RandData@=
@=4/ a12bcd980763acddeab879/anchor1pos@=1/anchor1value@=5/drift1；
Wherein, type@=VerifyReq then indicates that this instruction is the association that the verifying topic that Platform Server issues is broadcast live
Discuss content；@=1540132018 item Timestamp indicate the current time stamp information of live streaming Platform Server, and the length is 10
Bit length；RandData@=a12bcd980763acddeab879 then indicates the random data that live streaming Platform Server generates, length
Degree is 22 bit lengths；Anchor1pos=1 item indicates that the location information of first anchor point is first numerical value；anchor1value@
The occurrence of the numerical value of first anchor point of=5 expressions must be 5；@=4 item drift1 indicate that drift value is 4, i.e., finally calculate
It is 4 that result data, which must have a value,.In this example, only one anchor value and a drift value, in practical application, there may be more
A anchor value such as ancho r2pos, anchor2value etc. or multiple drift value such as drift2, drift3 etc. are not done specifically herein
It limits.
103, client generates encryption KEY according to user information；
104, client splices the current time stamp of random data and client, obtains the encryption number that length is M
According to；
105, client generates the calculated result for meeting verifying and requiring according to encryption data and encryption KEY；
In the embodiment of the present application, after client receives verifying instruction, i.e., the length that live streaming Platform Server issues is N's
Random data and length are the current time stamp of the live streaming Platform Server of (M-N), i.e., after one section M data to client,
Client encrypts data, and is constantly iterated encryption to the result of encryption, and every encryption once can all be sentenced
Whether the data of disconnected encrypted result meet the requirement result of live streaming Platform Server.Client carries out the data of the position M of input
What is obtained after encryption is also one 32 encrypted results.It must be very fast and encryption data to meet calculating primary encryption
Length will not change, therefore in the embodiment of the present application, can choose and use blowfish algorithm as the calculation for calculating power verifying
Method.
To obtain calculated result, client first needs to calculate an encryption KEY according to user information, implements
Function can be such that
KEY=SHA512.Create (Timestamp+UserId+DeviceID+RoomId)；
Wherein, SHA512.Create is the calculating interface of HASH algorithm SHA512, and Timestamp is for indicating client
