Embodiment 1

[0051] figure 1 The structure of the communication system provided by Embodiment 1 of the present invention is shown, and for convenience of description, only the parts related to the embodiment of the present invention are shown.

[0052] In the embodiment of the present invention, the communication system includes: a master control terminal and a controlled terminal communicatively connected with the master control terminal, the controlled terminal generates a first serial number after receiving the authentication request sent by the master control terminal, and sends a response command to the master, the master generates a second serial number according to the first serial number, and sends command data to the controlled terminal, and the controlled terminal generates the second serial number and the first serial number according to the command data Numbers are compared, and when the second serial number differs from the first serial number by a first preset value, the comm...

Embodiment 2

[0058] figure 2 It shows the implementation flow of the communication method provided by Embodiment 2 of the present invention, image 3 It is an interaction sequence diagram of the communication method provided by the embodiment of the present invention, which is described in detail as follows:

[0059] In step S110, an authentication request sent by the master is received.

[0060] In the embodiment of the present invention, the authentication request includes authentication information, and the authentication information may include information such as the identification of the master control terminal, a communication protocol format of the authentication information, and a key.

[0061] In step S120, after the authentication is passed, a response command is sent to the master, and the response command carries a first serial number.

[0062] In the embodiment of the present invention, the step of passing the authentication specifically includes:

[0063] Judging whether...

Embodiment 3

[0079] Figure 4 It shows the implementation process of the communication method provided by the third embodiment of the present invention, which is similar to the second embodiment, except that, before the step of receiving the authentication request sent by the master control terminal, the method further includes:

[0080] In step S210, when the historical communication protocol fails, send failure information to the control terminal, where the failure information includes re-authentication information.

[0081] In the embodiment of the present invention, the historical communication protocol is a general communication protocol adopted when the master control terminal communicates with the controlled terminal. The general communication protocol can be a network communication protocol (TCP, UDP, HTTP, etc.), wireless or wired communication protocol.

[0082] In this embodiment of the present invention, the failure of the historical communication protocol includes that the ne...

Abstract

The invention is applicable to the field of smart home, and provides a communication method, device and system, a readable storage medium and a computer device. The method comprises the following steps: receiving an authentication request sent by a main control end; after the authentication is passed, sending a response command to the main control end, wheein the response command carries a first serial number; receiving command data sent by the main control end, judging whether a second serial number carried in the command data is different from the first serial number by a first preset valueor not, and obtaining the second serial number through the first serial number and the first preset value; and if the judgment result is yes, responding to the command data. By dynamically changing the unique sequence value, the anti-attack capability of the intelligent equipment is provided, illegal data packets can be filtered out, and the security and the user experience are improved.

Description

technical field [0001] The invention belongs to the field of smart home, and in particular relates to a communication method, device, system, readable storage medium and computer device. Background technique [0002] With the development of the Internet of Things, smart homes have been widely used. Existing smart home devices can communicate with mobile terminals such as mobile phones or tablets through the network, so as to realize the management and control of smart home devices. Wi-Fi networking for remote control, providing users with convenience and a higher experience. [0003] However, because the current general network uses a general network protocol, and the general network protocol is easy to be cracked, which brings risks to the security of user information and equipment. The current security risks mainly come from two aspects: 1. Due to the breach of the network protection wall or the leakage of the key, a large number of illegal network data packets attack the...
