Description
Technical field
The present invention relates to internet communication, be specifically related to a kind of advertisement accurate method to designated equipment.
Background technology
In current mechanics of communication, existing digital signage is client-server pattern, and the benefit of this pattern is system
One management, unified resource.But drawback is, in the situation operational excellence that terminal is a small amount of, once many will cause to server
The biggest pressure, even server are delayed machine.Although can be solved by distributed type assemblies, but this also increases to operator
Many expenses, bring great economic pressures to operator.
MQTT communications protocol is limited for a large amount of computing capabilitys, and is operated in the long-range biography of low broadband, insecure network
Sensor or the agreement of communication control design, it has the property that
1) use publish/subscribe massage pattern, it is provided that the news release of one-to-many, release application program coupling；
2) the message transmission to load contents shielding；
3) TCP/IP is used to provide network to connect；
4) there are three kinds of news release service quality:
" the most once ", news release is completely dependent on bottom TCP/IP network.Information drop-out or repetition can occur.This rank can
For following situation, environmental sensor data, it doesn't matter to lose a read record, sends because the most also having second time.
" at least one times ", it is ensured that message arrive, but message repeat it may happen that.
" for once ", it is ensured that message arrives once.This rank can be used for following situation, in charge system, message
Repeat or loss can cause incorrect result.
Small-sized transmission, expense the least (head of regular length is 2 bytes), agreement exchange minimizes, to reduce network flow
Amount；
According to the characteristic of mqtt, selecting mqtt agreement to intercut message is an ideal method.
DES (Data Encryption Standard) is packet symmetric cryptographic algorithm.The packet that DES have employed 64 is long
Degree and the key length of 56, the input of 64 is obtained the output of 64 by it through a series of conversion.Deciphering then employs phase
With step and identical key.The key length of DES is 64, due to the n-th * 8 (n=1,2 ... 8) be check bit, therefore real
Border participates in a length of 56 of encryption, and key space contains 2^56 key.
DES algorithm utilizes repeatedly combination replacement algorithm and transposition algorithm, dispersion and the interaction of entanglement, establishment in plain text
Becoming the highest ciphertext of Cipher Strength, its encryption and deciphering are same algorithms.
DES algorithm, is a kind of product ciphers, and it mainly have employed the letters such as displacement, replacement, mould two addition on algorithm structure
Number, calculates by the way of round function iteration and works.
DES algorithm also can use data replacement technique, mainly has initial permutation IP and inverse initial permutation IP^-1 two kind
Type.DES algorithm uses the purpose of in-place computation to be that all forms and all data of original plaintext are all upset rearrangement.And
In wheel encryption function, data will all upset rearrangement, simultaneously in terms of data form, by original 32 bit data format, expand
Generated is 48 bit data format in order to meet S box group to data length and the requirement of data format specifications.
One group of data message, after a series of nonlinear transformation, is difficult to therefrom derive its process calculated and make
Nonlinear combination；If but this group data message uses linear transformation, calculating to be easy for many.At DES algorithm
In, the calculating process belonging to nonlinear transformation only has S box, and remaining data calculates and conversion is all belonging to linear transformation, so
The security intensity that it is critical only that S box of DES algorithm security.Additionally, S box and displacement IP cooperate, define the strongest robust
Dividing and attack and anti-linear attacking ability, wherein resisting differential attacking ability is more higher.
Summary of the invention
The present invention is directed to the problems referred to above, it is provided that the accurate method of a kind of advertisement to designated equipment.
The technical solution used in the present invention is: the accurate method of a kind of advertisement to designated equipment, comprises the following steps:
S1, selects the resolution of advertising scenarios；
S2, is dragged to corresponding position control to be configured, and arranges the attribute needed for control；
S3, preserves advertising scenarios, generates the HTML5 page；
S4, packing is compressed into a ZIP file；
S5, examination & verification is issued and by MQTT protocol propelling information to terminal；
S6, terminal deciphering message also downloads the advertisement ZIP file of compression；
S7, terminal decompresses and plays advertisement.
Further, described step 5 also includes:
S51, connection MQTT:
Generate connection string: specifying IP address and the port numbers of MQTT distribution of Message Agent main frame, port numbers default value is
1883；Connection attribute is set, including client computer mark, subscribe to type, send alive messages interval time；
Create MQTT client objects；
S52, to acting on behalf of topic of subscription: subscription is by MQTT object handles, including two array parameters, i.e. topic of subscription array,
Service quality array；
S53, gives out information to digital signage: directly use the api function publish that MQTT provides, it is desirable to provide theme, disappear
The parameters such as breath, service quality；
S54, receives the message from agency: for making application receive the message of subscription, creates a readjustment and processes function, and
At MQTT client registers；
With MqttSimpleCallback interface create simple interface object, and realize connectionLost,
Tri-methods of deliveryComplete and messageArrived；
When the connection with agency surprisingly terminates, just call connectionLost method；If this occurs, then this side
Method attempts to reconnect to agency；If connectionLost method cannot reconnect, then can notify visitor by throw exception
Family machine reconnects unsuccessfully；
The message of messageArrived method notice system topic of subscription has arrived client；
Whether deliveryComplete method representation sends and completes；
S55, needs des encryption before news release.
Further, described step S6 also includes: after digital signage subscribes to message, and agency issues what digital signage was subscribed to
Theme, digital signage receives the message of issue and deciphers.
Further, described step S7 also includes: to correlative code encryption and deciphering.
Advantages of the present invention:
The method of the present invention is simple to operate, reduces the pressure of server, alleviates the service fee of operator, discharge clothes greatly
