Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The topic encrypted content being related in the application for ease of understanding, below briefly introduces to encryption principle, please join
Fig. 1 is read, information encryption can be divided into three classes: symmetric cryptography, asymmetric encryption and one-way hash encryption.
Symmetric cryptography refers to that encryption and decryption use the same key (or can mutually calculate).Symmetric cryptography
It is generally used for the occasion that information needs secure exchange or storage, such as Cookie encryption, communication encryption, common symmetric cryptography are calculated
Method has DES algorithm, RC algorithm etc..The advantages of symmetric cryptography is that algorithm is simple, and encryption and decryption is high-efficient, and overhead is small, suitable pair
Mass data is encrypted；The disadvantage is that encryption and decryption uses the same key, need to face how the exchange key of safety
Problem, if key is lost, all encryption information will be easy to be cracked, and by taking DES algorithm as an example, what is generated is close
Key only has 56, and encryption strength is not high, further, since DES algorithm full disclosure, the guarantor that safety places one's entire reliance upon to key
Shield, it is necessary to there is reliable channel to distribute key.
Asymmetric encryption refers to encrypting and what decryption used is not the same key, one of them is open to the external world, claims
Make public key, another only has the owner to know, is referred to as private key.It must can just be unlocked with private key with the information of public key encryption, instead
It, must can just be unlocked with the information of private key encryption with public key.Asymmetric encryption techniques are generally used for safe information transmission, number
Occasions, the common algorithms such as signature have RSA Algorithm etc..The advantages of asymmetric encryption is that code key distribution is convenient；The disadvantage is that encryption and
Decrypting process is computationally intensive, and encryption/decryption speed is slow.For reduce calculation amount, when transmit information, frequently with symmetric encryption method with
The mode that asymmet-ric encryption method combines, i.e. information are encrypted using DES session key, then using RSA key encryption dialogue
Key and informative abstract after other side receives information, are made a summary with different key decryption session key and cross-check information.It is thus real
Showing DES for encrypting in plain text, RSA is used for the encryption of DES key, and des encryption speed is fast, it is suitble to the longer message of encryption, and
RSA can solve the problem of DES encryption key distribution.
One-way hash encryption, which refers to, carries out hash calculating by the information to any input length, obtains the defeated of regular length
Information out, common one-way Hash algorithm have MD5, SHA etc..It the characteristics of using one-way hash encryption, can be to arbitrary size
It inputs information and carries out encrypting storing.For carrying out encrypting storing to password, the password that user inputs in registration is not protected directly
It is stored to database, but one-way hash encryption is carried out to password, the ciphertext of generation is saved in the database, when user steps on again
When record, input information carries out password authentification, and the information of user's input obtains the close of input information after similarly hashing calculating
Text compares the ciphertext saved in the ciphertext and database that input information, if unanimously, password authentification success.Unidirectionally
Hash encryption the advantages of be Hash computation processes be it is irreversible, i.e., can not be counted by the output information to regular length
It calculates to obtain input information；The disadvantage is that same Encryption Algorithm can generate identical output information for identical input information,
The attack pattern of look-up table, reversed look-up table and rainbow table can be used in people, cracks input information.
In order to increase the safety of uni-directional hash calculating, salt figure can be used in hashing algorithm, salt figure is equivalent to encryption
Key.By taking MD5 as an example, MD5 belongs to hash algorithm one kind, which can run the numerical value of random length, generates one
A 128 hashed values (hash value), MD5 itself be it is irreversible, but it is identical input information generate hashed value
Be it is identical, this make people can use leakage password database it is counter inquired, for the defect of MD5, can be used
Salt figure further increases its safety, one group of character string that salt figure is randomly generated, may include random upper and lower case letter,
Number and character, digit can be different according to requiring, and after salt figure, identical input information may finally generate difference
Output information, allow for standard cipher library in this way and do not existed, considerably increase people crack input information difficulty.When
So, the above salt figure that is introduced into MD5 algorithm is that one in present embodiment applies example, and in practical applications, salt figure is same
Sample can be applied to other algorithms.
Live streaming answer is substantially a kind of live scene for introducing answer interaction, compared to common net cast system
System, increases instructor in broadcasting's platform and answer server in live streaming answering system, and instructor in broadcasting's platform sends phase according to the live scene at main broadcaster end
Answer instruction is closed, answer server distributes topic to the movable viewer end of answer is participated in, and after viewer end answer finishes topic
Answer is collected as a result, answer server can also compare topic correct option and the answer being collected into result, to judge to see
Whether many ends answer correctly, and the viewer end answer situation of statistics is sent to main broadcaster end.It in this application, is guarantee answer service
Device can distribute topic information in time, and collect answer as a result, topic relevant information and live video in answer activity is broadcast live
Stream is to separate transmission, and answer server by utilizing instant communication protocol transmits topic relevant information, and main broadcaster end utilizes biography
The live video agreement (including but not limited to RTMP, HDL and HLS protocol) of system pushes live video stream.
Topic distribution method provided by the present application is applied in live streaming answering system, is stored in above-mentioned live streaming answering system
Complete the topic information ciphertext of encryption.
Live streaming answer activity start before, be broadcast live platform in encryption server can be used symmetric cryptography, it is asymmetric plus
The Encryption Algorithm such as one or more of this three of close, one-way hash encryption combination encrypt topic information in plain text, this
Apply to this with no restriction.It include item content, topic option and topic correct option in above-mentioned topic information plaintext.Live streaming
Platform is sent to answer server, the storage of answer server after completing relevant encrypted work, by the topic information ciphertext of generation
Deposit above-mentioned topic information ciphertext.It is important to note that above-mentioned topic information ciphertext includes that topic problem ciphertext and topic are answered
Case ciphertext two parts, wherein topic problem ciphertext can specifically include item content ciphertext and topic option ciphertext.In the application
In, answer server and encryption and the decrypting process for being not involved in topic information, live streaming platform impertinence mesh number are encrypted, and
Be establish topic number and the mapping relations of topic information ciphertext, and above-mentioned mapping relations are sent to answer server so that
It obtains answer server and can be numbered according to topic and feed back corresponding topic information ciphertext.It is important to note that same letter
When breath is repeatedly encrypted, if using identical key and identical Encryption Algorithm in ciphering process, the ciphertext generated
It is also identical.Since in actual live streaming answer activity, general in topic information only includes tetra- options of A, B, C, D, institute
The form of expression with topic correct option is usually some letter in A, B, C, D, and the table of the correct option of different topics
Existing form may be identical, such as all be " A ", if this results in live streaming, platform uses identical key and identical encryption
Algorithm encrypts the topic correct option of different topics, identical topic answer ciphertext may be generated, in such case
Under, by analysis topic answer ciphertext and the topic correct option announced, can determine alphabetical A, letter b, letter C and
The corresponding relationship of alphabetical D and ciphertext.
For example, the correct option of topic 1 and the correct option of topic 5 are all A, live streaming platform uses identical key
The correct option of topic 1 and the correct option of topic 5 are encrypted with identical Encryption Algorithm, it is clear that generated after encrypting twice
Topic answer ciphertext be identical.Assuming that the ciphertext generated after encrypting to alphabetical " A " is " &5@3 ", people pass through collection
The correct option " A " announced after ciphertext " &5@3 " and answer, can determine alphabetical " A " by above-mentioned key and it is above-mentioned plus
The ciphertext generated after close algorithm for encryption is " &5@3 ", in this way during subsequent answer, when a certain problem purpose topic of discovery is answered
Case ciphertext is " &5@3 " when, it can determine that the correct option of the topic is " A ", it is clear that this is unfavorable for the guarantor of topic correct option
It is close.
In one embodiment, it when live streaming platform encrypts topic information in plain text, can correctly be answered in topic
Random number is added in case.For example, the correct option of topic 1 and the correct option of topic 5 are all A, live streaming platform to topic just
When true answer is encrypted, random number " 451319ah " can be added after the correct option (i.e. alphabetical " A ") of topic 1,
Random number " dgk42ui " is added after the correct option (i.e. alphabetical " A ") of topic 5, the performance shape of the correct option of such topic 1
Formula has reformed into " A451319ah ", and the form of expression of the correct option of topic 5 has reformed into " Adgk42ui ", it is clear that even if straight
It broadcasts platform to encrypt " A451319ah " and " Adgk42ui " using identical key and identical Encryption Algorithm, generate
Ciphertext be also different, can thus be duplicated to avoid topic answer ciphertext, so improve topic correct option guarantor
Close property.Correspondingly, live streaming platform also needs to establish topic number after live streaming platform adds random number in topic correct option
With the mapping relations of random number, sent so that platform is broadcast live during subsequent decryption and can be numbered according to topic to decryption side
Corresponding random number, the topic information after guaranteeing decryption can be interpreted correctly in plain text.
It is important to note that one group of character string that random number can be randomly generated, including but not limited to capital and small letter
Letter, number and character, random number can add before topic correct option or after topic correct option, the application couple
The concrete form of random number with no restriction, need to only guarantee the form of expression difference of topic correct option after addition random number.
In another embodiment, it when live streaming platform encrypts topic information in plain text, can be directed to different
Topic uses different keys, this can also be duplicated to avoid topic answer ciphertext, and then improves the guarantor of topic correct option
Close property.Correspondingly, live streaming platform also needs to establish topic volume after live streaming platform uses different keys for different topics
Mapping relations number with key are sent so that platform is broadcast live during subsequent decryption and can be numbered according to topic to decryption side
Corresponding key guarantees that topic information ciphertext can be properly decrypt.
