In one embodiment, as shown in fig. 2, a data synchronization method in a networking environment is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
The wireless Mesh network has evolved into an effective solution suitable for various wireless access networks such as a broadband home network, a community network, an enterprise network, a metropolitan area network and the like by virtue of multi-hop interconnection and Mesh topology characteristics. Data synchronization between Mesh devices can enable the MESH routing to be more intelligent, service perception is more flexible, and the Mesh devices have more flexible service perception capability and processing capability. Meanwhile, the intelligent wireless router can be used for conveniently connecting other wireless devices, the router serves as an intelligent home data inlet, unified networking can be conducted on the intelligent home, the data interfaces are combined with the cloud, and after the intelligent router has storage and computing capabilities, the home devices can be remotely controlled to work, so that the intelligent router is not only a network access device, but also a management device and a safety device.
Mesh networks, i.e. "wireless Mesh networks", are "multi-hop" (multi-hop) networks, Mesh being a wireless network technology. The wireless Mesh router forms an ad hoc network in a multi-hop interconnection mode, and provides WMN networking with higher reliability, wider service coverage and lower early investment cost. The WMN is a special form of the mobile Ad Hoc network, and is a high-capacity high-speed distributed network. The general architecture of WMN consists of three different types of radio network elements: gateway routers (routers with gateway/bridge functionality), Mesh routers (access points) and Mesh clients (mobile or otherwise). The Mesh client is connected to the wireless Mesh router in a wireless connection mode, and the wireless Mesh router forms a relatively stable forwarding network in a multi-hop interconnection mode. A common Mesh networking adopts a client/server technical model, a Mesh master device runs at a server side, and a Mesh slave device runs at a client side and is mainly used for synchronizing parameters of wifi.
Specifically, the master device running at the server may receive a registration request sent by the slave device, where the registration request carries device information corresponding to the slave device. The master device is a Mesh master device, the slave device is a Mesh slave device, the Mesh master device runs on a server side, and the Mesh slave device runs on a client side. The registration request means that the slave device registers its device information and its service information to the corresponding resource management device. The device information refers to identification information related to the device, such as a device model number, a serial number, and the like. The device information may include information such as the device model, the device manufacturer (e.g., Microsoft), the operating system and version (e.g., iOS 12.0.1), the device owner, the device name, the device serial number, and the IMEI. The master device in the Mesh-based networking environment is taken as an example for explanation. And the Mesh master device is started, opens a TCP2000 port and waits for external connection. The Mesh slave device is started, after the corresponding IP address is obtained through the WAN port, the Mesh slave device is connected with the TCP2000 port of the Mesh master device, the Mesh slave device initiates a registration request to the Mesh master device, meanwhile, the Mesh slave device sends the device information of the Mesh slave device to the Mesh master device, and the Mesh master device is requested to send the corresponding configuration information. When the Mesh master device receives the registration request and the device information sent by the Mesh slave device, the Mesh master device responds to the confirmation message corresponding to the Mesh slave device and indicates that the information sent by the slave device is received.
And step 204, judging whether the slave equipment is legal or not according to the equipment information.
After the master device receives the registration request sent by the slave device, the master device may determine whether the slave device is legal according to the device information of the slave device carried in the registration request. Whether the equipment is legal or not means whether the equipment information and the service information of the equipment conform to the configuration information set in the current resource management equipment or not, namely whether the identity of the equipment is verified or not is illegal. Specifically, after the Mesh master device, i.e., the Mesh master device, receives the registration request sent by the Mesh slave device, i.e., the Mesh slave device, the Mesh master device may respond to the confirmation message corresponding to the Mesh slave device, indicating that the information sent by the Mesh slave device has been received. Further, the mesh host and the mesh slave establish link keep-alive, start the link keep-alive and verify whether the master device and the slave device are on-line. That is, the master device first checks the physical link status corresponding to the slave device. If the physical link is normal, the mesh host checks whether the mesh slave is legal. The device information comprises information such as MAC information, a factory building mark and a product model, and the mesh host can judge whether the slave device is legal or not according to the preset configuration information and the information such as the MAC information, the factory building mark and the product model in the device information. In addition, the mesh host can also send the registration request to a third-party user terminal to confirm whether the mesh slave is legal or not, and the third-party user terminal judges whether to issue corresponding configuration information or not. And if the mesh host receives a message which is sent by the user terminal and confirms that the mesh slave is legal, the mesh host adds the mesh slave into a local legal list of the mesh host.
And step 206, if the slave equipment is legal, issuing corresponding configuration information to the slave equipment, and creating a linked list corresponding to the slave equipment. The linked list is used for storing data reported by the slave device, and the configuration information is encrypted by using a negotiated target key.
The master device may determine whether the slave device is legal according to the device information of the slave device carried in the registration request. And if the slave equipment is determined to be legal, the master equipment sends corresponding configuration information to the slave equipment and creates a linked list corresponding to the slave equipment. The linked list is used for storing data reported by the slave device, and the configuration information is encrypted by using a negotiated target key. Specifically, the mesh master can create and maintain a linked list for storing the data sent by the mesh slave, and after the master and the slave register successfully, the mesh master can store the data reported by the mesh slave in the corresponding linked list. The configuration information is used for indicating the slave device to update the corresponding configuration according to the configuration information, and the negotiated target key is that after the mesh slave device is connected with the TCP2000 port of the mesh host device, the mesh host device and the mesh slave device can perform a key negotiation process in advance through the TCP2000 port to obtain the negotiated target key.
And step 208, if the slave equipment is illegal, returning a result of failed registration to the slave equipment.
The master device may determine whether the slave device is legal according to the device information corresponding to the slave device carried in the registration request. And if the slave equipment is determined to be illegal, the master equipment returns a result of failed registration to the slave equipment. That is, when the mesh host determines that the slave device is illegal, the master device sends error information to the corresponding slave device, and prompts that the registration fails, that is, the slave device is an illegal user or an illegal device.
In this embodiment, by receiving a registration request sent by a slave device, the registration request carries device information corresponding to the slave device. And judging whether the slave equipment is legal or not according to the equipment information. And if the slave equipment is legal, issuing corresponding configuration information to the slave equipment, and creating a linked list corresponding to the slave equipment. The linked list is used for storing data reported by the slave device, and the configuration information is encrypted by using a negotiated target key. And if the slave equipment is illegal, returning a result of failed registration to the slave equipment. Therefore, the encryption and decryption of the related operations of data synchronization under the networking environment are realized through the target key negotiated in advance by the master device and the slave device, and the data synchronization efficiency can be effectively improved while the data synchronization safety is ensured.
In one embodiment, as shown in fig. 3, the step of generating the negotiated target key includes:
And when the slave equipment is determined to be legal, the master equipment sends the corresponding configuration information to the corresponding slave equipment and creates a linked list corresponding to the slave equipment. Wherein the configuration information is encrypted using the negotiated target key. The master device may negotiate the generation of the target key with the slave device in advance. Specifically, the master device may receive a negotiation request of the key generation manner sent by the slave device, where the negotiation request carries the key generation manner supported by the slave device itself. The master device selects a target key generation mode from the key generation modes supported by the slave device, and returns the target key generation mode to the slave device. The target key generation mode is used for indicating the slave equipment and the master equipment of communication to calculate and obtain a target key according to a Diffie-Hellman key exchange algorithm. The Diffie-Hellman KEY Exchange Algorithm refers to a method of ensuring that a shared KEY securely traverses an insecure network, called the Diffie-Hellman KEY Exchange protocol/Algorithm (Diffie-Hellman KEY Exchange/agent Algorithm). The mechanism is ingenious in that two parties requiring secure communication can determine a symmetric key by the method, and then can encrypt and decrypt by the key. Therefore, the encryption capability negotiation between the master device and the slave device is realized, and a preferable encryption mode can be provided for the related operation during data synchronization for transmission.
In one embodiment, as shown in FIG. 4, the step when a configuration change is detected includes:
And step 404, if the configuration information is not the same, sending the changed configuration file to the slave device, wherein the changed configuration file is used for indicating the slave device to update the corresponding configuration information.
The mesh host creates and maintains a linked list for storing the data sent by the mesh slave, and after the host and the slave are successfully registered, the mesh host stores the data reported by each mesh slave in the corresponding linked list. When the mesh host detects the configuration change, namely an administrator or a user terminal with the configuration change authority changes the configuration, the mesh host detects whether the local configuration data is the same as the data in the created linked list or not in a polling mode. And if not, the mesh host sends the changed configuration file to the corresponding slave equipment, wherein the changed configuration file is used for indicating the slave equipment to update the corresponding configuration information. For example, after the mesh master and the mesh slave 01 are successfully registered, when the mesh master detects a configuration change, that is, when an administrator or a user with a configuration change authority changes the configuration of the mesh slave 01, the mesh master detects whether local configuration data is the same as data in a created linked list of the mesh slave 01 in a polling manner. If the configuration information is not the same as the configuration information, the mesh master sends the changed configuration file to the corresponding mesh slave 01, so that the mesh slave 01 updates the corresponding configuration information. Therefore, the data synchronization security is ensured, and meanwhile, the resources consumed in data synchronization can be reduced. In addition, a json format is adopted during data exchange, machine analysis and generation are easy, network transmission efficiency can be effectively improved, expansibility of synchronous data is supported, new data nodes and services can be added, and new service scenes can be conveniently expanded.
In one embodiment, as shown in fig. 5, the step of determining whether the slave device is legal according to the device information includes:
In step 504, if the device information is not found, it is determined whether the device information meets the conditions of the preset legal device.
After receiving the registration request sent by the slave device, the master device may determine whether the slave device is legal according to the device information corresponding to the slave device carried in the registration request. Specifically, the master device may search a legal device list locally corresponding to the master device according to the device information. If not, further judging whether the equipment information meets the conditions of the preset legal equipment. And if so, determining that the slave equipment is legal, and adding the slave equipment into a legal equipment list locally corresponding to the master equipment. For example, after the mesh host receives the registration request sent by the mesh slave 01, the mesh host may determine whether the mesh slave 01 is legal or not according to the device information corresponding to the mesh slave 01 carried in the registration request. Specifically, the mesh master can search in a legal device list locally corresponding to the mesh master according to the device information corresponding to the mesh slave 01. If the information is not found, whether the device information corresponding to the mesh slave 01 meets the conditions of the preset legal device needs to be further judged. The mesh host can judge whether the slave equipment is legal or not according to the MAC information, the plant identification, the product model and other information in the equipment information. And if so, determining that the mesh slave 01 is legal, and adding the mesh slave 01 into a legal device list locally corresponding to the master device. In addition, the mesh master can search in a legal device list locally corresponding to the mesh master according to the device information locally corresponding to the mesh slave 01, and if the device information locally corresponding to the mesh slave 01 is searched in the legal device list locally corresponding to the mesh master, the mesh slave 01 is determined to be legal, and the mesh slave 01 is added into the legal device list locally corresponding to the master device. Therefore, the encryption and decryption of related operations of data synchronization in the networking environment are realized through the target key negotiated in advance by the master device and the slave device, meanwhile, a state machine can be designed according to the networking and data synchronization process, and the program running efficiency is improved.
In one embodiment, the device information is sent to the user terminal to confirm whether the slave device is legitimate.
After receiving the registration request sent by the slave device, the master device may determine whether the slave device is legal according to the device information corresponding to the slave device carried in the registration request. The master device may also send the device information corresponding to the slave device carried in the registration request to the user terminal to confirm whether the slave device is legal. For example, the mesh host may send the registration request to the third-party user terminal to determine whether the mesh slave is legal, and the third-party user terminal determines whether to issue the corresponding configuration information. And if the mesh host receives a message which is sent by the user terminal and confirms that the mesh slave is legal, the mesh host adds the mesh slave into a local legal list of the mesh host. Therefore, the encryption and decryption of the related operations of data synchronization under the networking environment are realized through the target key negotiated in advance by the master device and the slave device, and the data synchronization efficiency can be effectively improved while the data synchronization safety is ensured.
In one embodiment, as shown in fig. 6A, a data encryption method in a networking environment is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
And step 604, selecting a target key generation mode from key generation modes supported by the slave device, and returning the target key generation mode to the slave device, wherein the target key generation mode is used for instructing the slave device to generate a corresponding first public key and a corresponding first private key according to the target key generation mode.
And 606, generating a corresponding second public key and a second private key according to the target key generation mode.
And step 610, according to the target key generation mode, calculating the first public key and the second private key stored locally to obtain a target key.
The master device may receive, through a preset first port, a negotiation request of a key generation manner sent by the slave device, where the negotiation request carries a key generation manner supported by the slave device itself. The preset first port may be a TCP port. Further, the master device selects a target key generation method from key generation methods supported by the slave device itself, and returns the target key generation method to the slave device. The target key generation mode is used for indicating the slave device to generate a corresponding first public key and a corresponding first private key according to the target key generation mode, and the slave device sends the corresponding first public key generated according to the target key generation mode to the master device. Meanwhile, the master device may also generate a corresponding second public key and a second private key according to the negotiated target key generation manner. After the master device receives the first public key sent by the slave device through the first port, the master device may perform hybrid operation on the first public key and the second private key stored locally to obtain a corresponding target key. In addition, the master device also sends the second public key generated according to the negotiated target key generation method to the slave device, and after receiving the second public key sent by the master device, the slave device may perform a hybrid operation on the second public key and the first private key stored in the slave device according to the target key generation method to obtain the corresponding target key. The target key is used for encrypting and decrypting communication data between the master device and the slave device.
Specifically, as shown in fig. 6B, it is a flowchart of data synchronization in a Mesh networking environment. Fig. 6C is a flowchart of data synchronization software in a Mesh-based networking environment. And starting the Mesh master device, namely the Mesh host, opening a TCP2000 port and waiting for external connection. And the Mesh slave equipment, namely the Mesh slave machine is started up, acquires the IP address through the WAN port and is connected with the TCP2000 port of the Mesh host machine. Further, the mesh slave sends a request for a key generation mode negotiation to the mesh host, and sends a key generation mode (DH algorithm) supported by the mesh slave to the mesh host. After the mesh host receives the key generation mode set sent by the mesh slave, the mesh host selects a key generation mode (DH algorithm) also supported by the mesh host from the key generation mode set supported by the mesh slave, and responds the selected key generation mode (Diffie-Hellman key exchange algorithm) to the mesh slave, namely, the two parties complete the negotiation of the key generation modes. Further, the mesh slave side generates a first public key and a first private key by adopting a negotiated Diffie-Hellman key exchange algorithm, namely a DH algorithm, and sends the first public key of the mesh slave and the device information of the mesh slave to the mesh host. After the mesh host receives the first public key sent by the mesh slave through the TCP2000 port, the mesh host also generates a second public key and a second private key corresponding to the mesh host by adopting a negotiated DH algorithm, and returns the second public key to the mesh slave. And the mesh host calculates the first public key of the mesh slave and the second private key of the mesh host to obtain a corresponding shared key. And after receiving the second public key of the mesh host, the mesh slave side calculates the second public key of the mesh host and the first private key of the mesh slave to obtain a shared key, namely the negotiation process of the target key is finished. The mesh slave machine and the mesh host machine adopt the negotiated shared secret key to encrypt and decrypt communication data, and the encryption mode during message transmission is an AES mode. The AES, i.e., Advanced Encryption Standard (AES), also called Rijndael Encryption method, is a block Encryption Standard adopted by the federal government in the united states. Therefore, through a Diffie-Hellman key exchange algorithm, two parties needing communication determine a symmetric key by adopting a negotiated DH algorithm mode, and encrypt and decrypt by using the key, so that the shared key can be ensured to safely pass through an insecure network, the encryption capability negotiation between the master equipment and the slave equipment is realized, and an optimal encryption mode can be provided for related operations during data synchronization for transmission.
In an embodiment, before receiving, through the first port, a negotiation request of a key generation method sent by the slave device, the method further includes a step of binding the first port of the master device with the IP address, which specifically includes:
the first port of the master device is bound with the IP address in advance to obtain a corresponding binding relationship, and the binding relationship is used for enabling each slave device to automatically acquire the IP address.
The slave device acquires the IP address in a DHCP mode, and establishes connection with the first port of the master device according to the IP address.
Before the master device receives the negotiation request of the key generation mode sent by the slave device through the preset first port, the first port of the master device may be bound with the IP address in advance to obtain a corresponding binding relationship, and the binding relationship is used for enabling each slave device to automatically acquire the IP address. And each slave device acquires the IP address in a DHCP mode and establishes connection with the first port of the master device according to the IP address. The preset first port may be a TCP port. DHCP (Dynamic Host Configuration Protocol) is a network Protocol of a local area network, and means that a server controls a segment of IP address range, and a client can automatically obtain an IP address and a subnet mask allocated by the server when logging in the server. Specifically, the Mesh master device is started up, opens the TCP2000 port, and waits for external connection. And the Mesh slave device is started up, acquires the IP in a DHCP mode through a WAN port and is connected with a TCP2000 port of the Mesh host. Therefore, the encryption capability negotiation between the master device and the slave device is realized, and a preferable encryption mode can be provided for the related operation during data synchronization for transmission.
