Detailed Description
The embodiments of the present invention will be described in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 shows a flow chart of a packet packing method for data transmission provided by the present invention, and referring to fig. 1, the method is applied to a mobile terminal, and includes the following steps:
11. acquiring a first data packet sent by intelligent equipment, wherein the first data packet is generated based on equipment identification of the intelligent equipment;
12. calling a first SDK packaging interface to analyze the first data packet to obtain an equipment identifier of the intelligent equipment;
13. calling a second SDK packaging interface to package the equipment identifier to obtain equipment binding information;
14. generating a second data packet according to the equipment binding information and the distribution network information, and sending the second data packet to the intelligent equipment;
the first SDK packaging interface and the second SDK packaging interface are constructed based on the specification files of equipment manufacturers.
As to steps 11 to 14, it should be noted that, in the present invention, after the intelligent device enters the distribution network state, the intelligent device establishes communication with the mobile terminal, and transmits the device identifier to the mobile terminal. The mobile terminal judges whether a non-inductive distribution network is supported or not through the equipment identifier, and if the non-inductive distribution network is supported, the distribution network information and the equipment binding information are transmitted to the intelligent equipment. The intelligent device acquires the distribution network information to be connected with the router, then is connected with the cloud end through the router, and transmits the device binding information. The cloud interacts with the mobile terminal, the equipment binding information is verified, and equipment right confirmation is completed.
In the above description, the smart device needs to send the device identifier to the mobile terminal. In order to avoid that the intelligent equipment manufacturer informs the mobile terminal manufacturer of the format of the equipment identifier in advance, the method needs to package the equipment identifier on the intelligent equipment, wherein an SDK packaging interface is adopted to package the equipment identifier, the equipment identifier is packaged into a data packet (namely the first data packet mentioned in the step), and then the data packet is sent to the mobile terminal.
In the present invention, an SDK, a Software Development Kit, refers to a collection of Development tools used by a Software engineer to build application Software for a particular Software package, Software framework, hardware platform, operating system, etc.
In the invention, two SDK packaging interfaces, namely a first SDK packaging interface and a second SDK packaging interface, are provided and configured by an intelligent terminal manufacturer in the mobile terminal. The first SDK packaging interface and the second SDK packaging interface are constructed based on the specification files of equipment manufacturers.
The data packet received by the mobile terminal is obtained by processing the equipment identifier by adopting the first SDK packaging interface. The first SDK packaging interface is used for carrying out reverse processing on the received data packet so as to obtain the equipment identification of the intelligent equipment.
Therefore, the mobile terminal receives the data packet sent by the intelligent equipment, and the first SDK packaging interface is called to analyze the first data packet to obtain the equipment identifier of the intelligent equipment.
In the above description, the mobile terminal needs to feed back, to the smart device, device binding information for the smart device, where the device binding information is used for determining the right of the cloud and the mobile terminal to the smart device.
The intelligent device manufacturer is prevented from informing the mobile terminal manufacturer of the format of the device binding information in advance. The method of the invention needs equipment binding information to be packaged, wherein, an SDK packaging interface is also adopted to package the equipment binding information, and then the equipment binding information and distribution network information (SSID and password of a router) are packaged into a data packet (namely the second data packet mentioned in the step), and then the data packet is sent to the intelligent equipment.
In the invention, in order to distinguish the working property of the SDK packaging interface, the second SDK packaging interface is used for packaging the equipment identifier to obtain the equipment binding information.
Therefore, the mobile terminal calls the second SDK packaging interface to package the equipment identification to obtain the equipment binding information.
The method for packaging data transmission enables the mobile terminal and the intelligent equipment to have a uniform SDK packaging interface, can transmit the equipment identification and the equipment binding information between the mobile terminal and the intelligent equipment by using the same standard interface, avoids the mobile terminal from acquiring and processing each intelligent equipment field and binding information field, realizes the compatibility with the equipment data format requirements of different intelligent equipment manufacturers, and keeps the equipment field and the binding information field of the intelligent equipment manufacturers secret.
In the further method of the present invention, the explanation is mainly given to the processing procedure of obtaining the device binding information by calling the second SDK encapsulation interface to encapsulate the device identifier, specifically as follows:
generating a binding information structure body according to the equipment identifier;
generating a first ciphertext according to the first symmetric key, the first initialization vector and the binding information structure body; the first symmetric secret key is randomly configured by the intelligent equipment, and the first initialization vector is randomly generated in a symmetric encryption algorithm;
and packaging according to the first ciphertext and the first initialization vector to obtain the equipment binding information.
In this regard, it should be noted that, in the present invention, a second SDK encapsulation interface provided by the smart device vendor is called to generate a binding information structure for device binding based on the smart device vendor specification and the device identifier, and then a set of initialization vectors (i.e., first initialization vectors) is randomly generated.
And then, symmetrically encrypting the binding information structure body by using a symmetric key (namely a first pair of key) and an initialization vector sent by the intelligent equipment to generate a ciphertext (namely a first ciphertext), splicing the generated ciphertext and the initialization vector through an algorithm, and packaging the ciphertext and the initialization vector into equipment binding information.
According to the method, the binding information structure body for binding the equipment generated based on the manufacturer specification and the equipment identification of the intelligent equipment is encrypted and spliced through the SDK packaging interface, so that the equipment binding information transmitted between the mobile terminal and the intelligent equipment through the same standard interface is obtained, and the intelligent equipment can use the information conveniently.
In the further method of the present invention, the explanation of the processing procedure for generating the second data packet according to the device binding information and the distribution network information is mainly as follows:
generating a shared secret key according to the first symmetric secret key and the first public key;
generating a combined data packet according to the equipment binding information and the distribution network information;
generating a second ciphertext according to the shared secret key, the second initialization vector and the combined data packet;
and packaging according to the second ciphertext, the first public key and the second initialization vector to obtain a second data packet.
In contrast, in the present invention, after obtaining the device binding information, the mobile terminal needs to send the device binding information and the distribution network information to the intelligent device, so that the intelligent device is connected to the router according to the distribution network information, and further connected to the cloud. Here, the device binding information and the distribution network information need to be encapsulated and packaged to obtain a data packet, and then the data packet is sent to the intelligent device.
The mobile terminal firstly generates a group of public and private key pairs for key exchange randomly through a key generation algorithm, namely a first public key and a first private key.
And generating a shared secret key by using the first symmetric secret key and the first public key, and then generating a combined data packet by using the equipment binding information and the distribution network information, wherein the combined data packet represents that the equipment binding information and the distribution network information are used as one data packet.
And symmetrically encrypting according to the shared secret key, the second initialization vector and the combined data packet to generate a second ciphertext. And then, a second data packet is obtained by packaging according to the second ciphertext, the first public key and the second initialization vector.
In the further method, as the distribution network information is in the configuration format of the router, the data transmission can be realized by reasonably encrypting and packaging the distribution network information and the equipment binding information under the condition that the intelligent equipment has the distribution network requirement.
In the further method of the present invention, the explanation is mainly given to the processing procedure of calling the first SDK encapsulation interface to analyze the first data packet to obtain the device identifier of the intelligent device, which is specifically as follows:
performing packet processing on the first data packet to obtain an equipment field and a mobile terminal definition field;
performing inverse splicing processing on the equipment field to obtain a third ciphertext and a third initialization vector;
decrypting the third ciphertext to obtain a first symmetric secret key, a third initialization vector and a first plaintext;
performing inverse splicing processing on the first plaintext to obtain a second public key and an equipment identification structural body;
and obtaining the equipment identifier according to the equipment identifier structural body.
To this end, it should be noted that, in the present invention, the first data packet is obtained by the intelligent device encapsulating and packaging the device identifier by using the first SDK encapsulation interface, and for this reason, the mobile terminal invokes the same first SDK encapsulation interface to perform the reverse operation on the first data packet, so as to obtain the device identifier.
Table 1 shows the structure content of the first packet. Table 2 shows the structural content of the second packet.
TABLE 1
TABLE 2
The following explains the generation process of the second data packet by using a specific example, which specifically includes the following steps:
after receiving a first data packet sent by the intelligent device, the mobile terminal analyzes a packaged device field F1 by adopting a first SDK packaging (SDK1) interface, an SDK1 integrates a data analysis algorithm, firstly, reverse splicing processing is carried out to obtain an initialization vector iv3 and a ciphertext E1, the ciphertext E1 is decrypted by using symmetric secret keys K1 and iv3 to obtain a plaintext C1, after reverse splicing processing, a public key N1 and a device identification structure S1 of device end key exchange are obtained, an device identification structure S1 is analyzed to judge whether the device supports a noninductive distribution network, and a judgment result and the public key N1 are used as standard output of the SDK1 interface and fed back to the mobile terminal.
Referring to fig. 2, the mobile terminal receives the determination result, if the smart device does not support the non-inductive distribution network, the mobile terminal does not process the first data packet, if the smart device supports the non-inductive distribution network, the mobile terminal invokes a second SDK encapsulation interface (SDK2) provided by the smart device manufacturer to generate a set of binding information structure S2 for device binding according to the specification of the smart device manufacturer, and while invoking, the SDK2 synchronously transmits the binding information structure S2 to the cloud of the smart device manufacturer for backup through the mobile terminal. The mobile terminal simultaneously generates a group of initialization vectors iv1 randomly, S2 is symmetrically encrypted by using symmetric keys K1 and iv1 at the device end, and generated ciphertexts E2 and iv2 are spliced and encapsulated into device binding information F2 through an algorithm.
The mobile phone end encrypts the connected distribution network information R1 (SSID, password, channel, etc. of the router) and the device binding information F2 encapsulated by the SDK2 through a key exchange algorithm to generate an encrypted data packet G2.
Generating a shared key K2 by a key generation algorithm according to a symmetric key K1 and a public key N1, then generating a ciphertext E3 by the shared key K2, an initialization vector iv2 and a data packet G2, and then packaging according to the ciphertext E3, the public key N2 and the initialization vector iv3 to obtain a second data packet.
Fig. 3 shows a flow chart of a packet packing method for data transmission provided by the present invention, referring to fig. 3, the method is applied to an intelligent terminal, and includes the following steps:
31. packaging the equipment identification of the intelligent equipment by adopting a first SDK packaging interface to generate a first data packet, and sending the first data packet to the mobile terminal;
32. acquiring a second data packet sent by the mobile terminal, and analyzing the second data packet by adopting a second SDK packaging interface to obtain distribution network information and equipment binding information;
33. establishing connection with a cloud terminal through a router according to the distribution network information, and sending the device binding information to the cloud terminal;
the first SDK packaging interface and the second SDK packaging interface are constructed based on the specification files of equipment manufacturers.
With respect to step S31 and step S32, it should be noted that, in the present invention, after the intelligent device enters the distribution network state, the intelligent device establishes communication with the mobile terminal and transmits the device identifier to the mobile terminal.
In order to avoid that the intelligent device manufacturer informs the mobile terminal manufacturer of the format of the device identifier in advance, the intelligent device encapsulates the device identifier by using an SDK encapsulation interface, packages the device identifier into a data packet (i.e., the first data packet mentioned in the step), and then sends the data packet to the mobile terminal.
In the invention, two SDK packaging interfaces, namely a first SDK packaging interface and a second SDK packaging interface, are provided and configured by an intelligent terminal manufacturer in the mobile terminal. The first SDK packaging interface and the second SDK packaging interface are constructed based on the specification files of equipment manufacturers.
The processing of the first data packet and the generation of the second data packet by the mobile terminal are described in detail in the above description, and are not described herein again.
And the mobile terminal feeds the second data packet back to the intelligent equipment, and the intelligent equipment analyzes the second data packet by adopting a second SDK packaging interface to obtain distribution network information and equipment binding information.
And then, the intelligent device establishes connection with the cloud terminal through the router according to the distribution network information and sends the device binding information to the cloud terminal.
The method comprises the following specific steps: after the intelligent device receives the transmitted second data packet, the data packet is decrypted through a key exchange algorithm to obtain distribution network information and device binding information, and then the device binding information is analyzed to obtain a binding information structure. The intelligent device logs in the cloud end through the distribution network information connection router, transmits the binding information structure body to the cloud end, and checks the binding information structure body sent to the cloud end by the mobile terminal to complete binding.
The method for packaging data transmission enables the mobile terminal and the intelligent equipment to have a uniform SDK packaging interface, can transmit the equipment identification and the equipment binding information between the mobile terminal and the intelligent equipment by using the same standard interface, avoids the mobile terminal from acquiring and processing each intelligent equipment field and binding information field, realizes the compatibility with the equipment data format requirements of different intelligent equipment manufacturers, and keeps the equipment field and the binding information field of the intelligent equipment manufacturers secret.
In the further method of the present invention, the explanation is mainly given to a processing procedure of encapsulating the device identifier of the smart device by using the first SDK encapsulation interface to generate the first data packet, which is specifically as follows:
generating an equipment identification structural body according to the equipment identification;
generating a first plaintext according to the second public key and the equipment identification structural body;
generating a third ciphertext according to the first symmetric key, the third initialization vector and the first plaintext;
generating a device field according to the third ciphertext and the third initialized vector;
and generating a first data packet according to the equipment field and the mobile terminal definition field.
In this regard, it should be noted that, in the present invention, the smart device configures the device identifier into the device identifier structure according to the specification file. And then, encrypting the equipment identification structure body by using a public key in a public and private key pair which is randomly generated to generate a plaintext. The plaintext is then used to generate a ciphertext based on the symmetric key and the initialization vector. And generating a device field by the ciphertext and the previous initialization vector, generating a first data packet by the device field and the mobile terminal definition field, and sending the first data packet to the mobile terminal.
The following explains the generation process of the first data packet by using a specific example, which specifically includes the following steps:
referring to fig. 4, after the smart device enters a distribution network mode, a public and private key pair N2 and D2 for key exchange is randomly generated through a key generation algorithm and stored, a public key N2 and unique identification structure body data of the device defined by a device manufacturer are spliced through a certain algorithm to generate a plaintext C1, the splicing algorithm is formulated by the smart device manufacturer, and the smart phone manufacturer does not need to know the splicing algorithm.
The manufacturer of the intelligent device generates a group of symmetric encryption keys K1 in advance and stores the keys in the intelligent device, and the keys need to be kept secret and cannot be leaked. A group of initialization vectors iv1 is generated through a random number algorithm, C1 is symmetrically encrypted through symmetric keys K1 and iv1, ciphertexts E1 and iv1 generated through encryption are spliced through an algorithm to generate an intelligent device field F1, then a first data packet is generated through the device field and a mobile terminal definition field, and the first data packet is sent to the mobile terminal.
In the further method of the present invention, the explanation is mainly given to the processing procedure of analyzing the second data packet by using the second SDK encapsulation interface to obtain the distribution network information and the device binding information, which is specifically as follows:
performing packet processing on the second data packet to obtain a second ciphertext, a first public key and a second initialization vector;
decrypting the second ciphertext to obtain a shared secret key, a second initialization vector and a combined data packet;
and performing sub-packet processing on the combined data packet to obtain equipment binding information and distribution network information.
After receiving the second data packet transmitted by the mobile phone, the smart device first decrypts the second data packet through a key exchange algorithm to obtain a ciphertext E3, a public key N2, and an initialization vector iv 3. The ciphertext E3 is then decrypted to obtain the shared key K2, the initialization vector iv2, and the data packet G2.
Processing the data packet G2 by adopting an SDK packaging interface to obtain distribution network information and equipment binding information, analyzing the equipment binding information to obtain a symmetrically encrypted initialization vector iv2 and a symmetrically encrypted ciphertext E2, and decrypting the ciphertext E2 by using the symmetric keys K1 and iv1 to obtain an equipment binding information structure S2. The intelligent device logs in the cloud end through the distribution network information connection router, transmits the binding information structure body to the cloud end, and checks the binding information structure body sent to the cloud end by the mobile terminal to complete binding.
