The target intelligent device may be any intelligent device in an implementation environment, and the intelligent gateway may be any intelligent gateway in the implementation environment. As shown in fig. 3, the network allocation method of the intelligent device includes:

step 301, the target intelligent device broadcasts a network allocation request. The distribution network request includes a target device identification of the target smart device.

In this embodiment of the present application, when the target intelligent device enters the network configuration state, the network configuration request may be broadcasted, so that the intelligent gateway receives the network configuration request and provides the network configuration service for the target intelligent device.

For example, the target intelligent device may broadcast the probe request message under the condition of entering the network configuration state, so that the intelligent gateway receives the probe request message, analyzes the probe request message, and obtains the network configuration request carried by the probe request message.

And 302, the intelligent gateway generates a target device key by adopting an installation password generation method according to the target device identifier.

In this embodiment of the present application, after receiving a network allocation request broadcast by a target intelligent device, the intelligent gateway may generate a target device key by using an installation password generating method according to a target device identifier.

And the third party equipment transmits the reference key information to the intelligent gateway in an out-of-band transmission mode so as to restrict the object of the intelligent gateway which can provide the distribution network service by utilizing the reference key information. And, because the reference key information indicates that the device distribution network key of the distribution network object is ciphertext data, but not plaintext data of the device identifier of the distribution network object. Therefore, the information security of the reference key information is effectively ensured, and the monitored risk is reduced.

It should be noted that, the implementation manner of generating the target device key of each intelligent device by the third party device is the same as the implementation manner of generating the target device key by the intelligent gateway. Therefore, the third party device adopts the installation password generating method according to the device identifier of each intelligent device, and the description of the implementation manner of generating the target device key of each intelligent device by adopting the installation password generating method according to the target device key of the target intelligent device by the intelligent gateway can refer to the following description, which is not repeated in the embodiment of the present application.

For example, the intelligent device of the wireless access point target geographic area corresponding to the intelligent gateway is preset manually. The third party device can collect the intelligent devices in the target geographic area, namely the device identifiers of the connectable intelligent devices, further generates a target device key of each intelligent device by adopting an installation password generation method according to the device identifier of each intelligent device, and establishes a reference key table which records reference key information. The third party device writes the reference key table into the target database in an out-of-band transmission mode, so that the intelligent gateway can read the reference key information from the target database.

The third party equipment adopts an installation password generating method according to the equipment identification, and the process of generating the equipment distribution network key comprises the following steps: and generating a device distribution network key through a hash function according to the device identification.

Accordingly, the process of generating the target device key by the intelligent gateway according to the target device identifier by using the installation password generation method may include step S11. In step S11, the intelligent gateway generates a target device key through a hash function according to the target device identifier.

In a second alternative implementation, the installation password generation method is a key generation method supported by the instrumentation Code technology. The third party equipment adopts an installation password generating method according to the equipment identification, and the process of generating the equipment distribution network key comprises the following steps: an initial key value and a salt value are determined based on the device identification. And generating a device configuration key with the length of the reference key by adopting a key derivation method according to the initial key value, the salt value, the reference iteration number and the reference key length.

In an alternative implementation, the third party device randomly generates an initial key value based on the device identification of the smart device, and determines the device identification of the smart device as the salt value. Thus, the randomness of the generated device distribution network key of the intelligent device can be ensured.

In another alternative implementation, the device identification of the smart device includes: first data and second data. The third party equipment determines the first data in the equipment identifier of the intelligent equipment and splicing data of the reference random number as an initial key value; and determining second data in the device identification of the intelligent device as a salt value.

For example, the third party device determines the PIN of the smart device as an initial key value and the MAC address of the smart device as a salt value.

Accordingly, the intelligent gateway adopts the installation password generating method according to the target device identifier, and the process of generating the target device key can include steps S21 to S22.

In step S21, an initial key value and a salt value are determined from the target device identification.

In an alternative implementation, the intelligent gateway randomly generates an initial key value according to the target device identification, and determines the device identification of the intelligent device as the salt value.

In another alternative implementation, the target device identification includes: first data and second data. The intelligent gateway determines the spliced data of the first data in the target equipment identifier and the reference random number as an initial key value; and determining the second data in the target equipment identifier as a salt value.

In yet another alternative implementation, the target device identification includes: first data and second data. The intelligent gateway determines first data in the target equipment identifier as an initial key value; and determining the second data in the target equipment identifier as a salt value.

Corresponding example, the smart gateway determines the PIN of the target smart device as the initial key value and the MAC address of the smart device as the salt value.

In step S22, a key derivation method is used to generate a target device key with a length equal to the reference key length according to the initial key value, the salt value, the reference iteration number and the reference key length.

Alternatively, the key derivation method can be a cryptographic derivation algorithm such as KDF, HKDF, PBKDF2, bcrypt, scrypt or Argon 2. Specifically, for example, the key derivation method may be a HMAC-SHA 256-based cryptographic derivation algorithm to ensure good entropy distribution and security.

Illustratively, the key derivation method is exemplified by a KDF key derivation algorithm. And the intelligent gateway generates a target equipment key by adopting a key derivation method according to the initial key value, the salt value, the reference iteration number, the reference key length and the first formula. The first formula satisfies: k=kdf (x 1, x2, x3, x 4). K represents the target device key. x1 represents the initial key value of the target smart device. x2 represents the salt value of the target smart device. x3 represents the reference iteration number. x4 denotes a reference key length.

The reference key length may be a length of transmission data specified by a related transmission protocol of the smart device and the smart gateway. For example, a bluetooth connection is used between the smart device and the smart gateway. The reference key length may be 128 bits, i.e. 16 bytes, of transmission data specified by the bluetooth transmission protocol. The value of the reference iteration number can be set in a self-defined manner. The larger the value of the reference iteration number is, the higher the security of the equipment distribution network key generated based on the reference iteration number is. Illustratively, the reference iteration number may be 1000, 1500, 2000, or the like.

In some embodiments of the present application, the device distribution network key in the reference key information may be updated periodically. The equipment distribution network key of the distribution network object corresponding to the intelligent gateway can be updated periodically, so that the safety of the equipment distribution network key is ensured, and the distribution network safety is further ensured.

Alternatively, in different update periods of the reference key information, the initial key values corresponding to the smart devices are the same, and the salt values are the same. Or in different updating periods of the reference key information, the initial key value and the salt value corresponding to the intelligent device are different.
