Step 401, determining plaintext according to the address of the gateway device and the total time of the current time group.
In an example implementation, the low order 0-3 bytes of the plaintext are the preset universal sync word 0x6deb98e8, the low order 4-7 bytes are the total number of times of the current time group, the 8-13 bytes are the address of the gateway device, and the remaining 14-216 bytes are all 0.

The inputs of the aes-128 encryption engine are a key with the length of 16 bytes and a plaintext with the length of 16 bytes, and the generated output is a ciphertext with the length of 16 bytes, which belongs to hardware encryption. Of course, the first scrambling code may also be obtained by encrypting by other encryption engines, which is not particularly limited in the embodiment of the present application.
In the embodiment of the application, the plaintext is determined according to the address of the gateway equipment and the total time of the current time group, the plaintext and the network key of the gateway equipment are input into the preset encryption engine to obtain the first scrambling code, and the first check code can be further determined through the determined first scrambling code.

In an example implementation, the first scrambling code may be bitwise exclusive-ored with a current original PDU field of the gateway device, calculated as a scrambled PDU field.
The current original PDU field is the communication basic data of the peripheral device and the gateway device, namely, the normal communication between the peripheral device and the gateway device can be carried out after the communication basic data exists in the peripheral device.
The gateway device sends the first check code, the address of the gateway device and the total time of the current time group to the peripheral device, and simultaneously sends the disturbing PDU field to the peripheral device, namely the source packet sent by the gateway device to the peripheral device comprises the first check code, the address of the gateway device and the total time of the current time group and also comprises the disturbing PDU field.
When the peripheral equipment determines the second check code and judges that the second check code is the same as the first check code, after the network access operation of the peripheral equipment for the gateway equipment is completed, the peripheral equipment continues to determine a second scrambling code according to the network key of the peripheral equipment, the address of the gateway equipment in the information source packet and the total time of the current time group in the information source packet, and determines the current original PDU field according to the second scrambling code and the scrambling PDU field. The method for determining the second scrambling code is the same as the method for determining the first scrambling code by the gateway equipment, and the plaintext is determined first, and then the second scrambling code is obtained according to the plaintext and the network key of the peripheral equipment. The method for determining the current original PDU field is the same as the method for obtaining the scrambled PDU field by the gateway equipment, and the second scrambling code and the scrambled PDU field are subjected to bit exclusive OR calculation to obtain the current original PDU field.
After the peripheral device calculates the current original PDU field, the current original PDU field is stored, so that normal communication interaction can be carried out between the gateway device and the peripheral device.
In the embodiment of the application, after the network access operation is performed, the current original PDU field is determined according to the disturbing PDU field in the information source packet and stored, so that the peripheral equipment can perform normal communication with the gateway equipment after the network access.
On the basis of the network access communication method of the above embodiment, the embodiment of the present application further provides a network access communication method, as shown in fig. 5, where the method further includes the following steps.
Step 501, determining a first signal synchronization word according to a first scrambling code.
After performing network access operation and storing the current original PDU field, the gateway device can perform data interaction with the peripheral device, and at this time, the gateway device sends a synchronization data packet to the peripheral device, where the synchronization data packet includes request data and a first signal synchronization word. The first signal synchronous word is intercepted from the first scrambling code.
Step 502, a first signal syncword is sent to a peripheral device.
After receiving the synchronous data packet, the peripheral equipment compares the first signal synchronous word in the synchronous data packet with the second signal synchronous word obtained by the peripheral equipment through calculation, if the first signal synchronous word is the same as the second signal synchronous word, the peripheral equipment performs data interaction with the gateway equipment, namely, the peripheral equipment determines response data according to the request data in the synchronous data packet and sends a response packet carrying the response data to the gateway equipment, and after receiving the response packet, the gateway equipment sends a response confirmation packet to the peripheral equipment.
In the embodiment of the application, the method for obtaining the second signal synchronization word by the peripheral device is the same as the method for obtaining the first signal synchronization word by the gateway device.
In the embodiment of the application, after network access operation and current original PDU field storage are performed by the peripheral equipment, normal communication data interaction between the peripheral equipment and the gateway equipment is performed according to the first signal synchronization word and the request data.
On the basis of the network access communication method of the embodiment shown in fig. 5, the embodiment of the present application further provides a network access communication method, as shown in fig. 6, in the step 501, a first signal synchronization word is determined according to a first scrambling code, and the method further includes the following steps.
In step 601, a first byte section of a predetermined length is selected from the low order bits of the first scrambling code.
In an example implementation, starting from the low order bits of the scrambling code, 4 bytes may be taken as the first byte section.
Step 602, according to a preset validity condition, validity checking is performed on a first byte section with a preset length.
Wherein, the preset validity condition is: without at least 6 consecutive 0's or 1's, each byte value cannot be equal, no more than 24 value flips, and at least 2 value flips for the upper 6 bits.
If the validity check is not passed, step 603, reselecting a second byte section of a preset length different from the first byte section of the preset length from the first scrambling code until the second byte section of the preset length passes the validity check, and taking the second byte section of the preset length as the first signal synchronization word.
If the first byte section does not meet the preset validity condition, the validity check is not passed, 4 bytes from the lower 2 bits of the scrambling code are selected as second byte sections, the validity check is continued, and if the validity check of the second byte sections is passed, the second byte sections of the 4 bytes are used as first signal synchronous words. If neither the first byte section nor each second byte section selected from the first scrambling code passes the validity check, a common syncword is used, which may be, for example: 0x6deb98e8.
The application embodiment realizes the determination of the first signal synchronization word according to the first scrambling code by checking the validity of the byte section in the first scrambling code.

In step 805, if the second signal synchronization word is the same as the first signal synchronization word, the peripheral device performs data interaction with the gateway device.
If the second signal synchronous word is the same as the first signal synchronous word, the peripheral equipment determines response data according to the request data in the synchronous data packet, and sends a response packet carrying the response data to the gateway equipment.
