Abstract

The invention discloses an intelligent household appliance remote control method based on a PKI system, which relates to the field of remote control of intelligent household appliances. The method comprises the steps that: firstly, a to-be-controlled intelligent household appliance is subjected to personalized setting; the intelligent household appliance decrypts ciphertext data sent by a control terminal and further accesses a wireless local area network; under coordination of a cloud server, and by taking a device certificate as a root of trust, a binding relation between the control terminal and the intelligent household appliance is established; and finally, the intelligent household appliance is controlled through the control terminal. In the intelligent household appliance remote control method based on the PKI system, functions, such as network identity recognition, network communication secrecy keeping, communication data tampering prevention and communication subject non-repudiation, are realized through a PKI key system technology, the data used in a communication process are all transmitted in a ciphertext mode, security of the data is guaranteed by strength of an encryption algorithm used, thus, problems, such as tampering of the communication data and information leakage, are avoided, and various security risks in the existing intelligent household appliance remote control method are solved.

Description

technical field [0001] The invention relates to the field of remote control of smart home appliances, in particular to a method for remote control of smart home appliances based on a PKI system. Background technique [0002] Smart home appliances have interconnection functions such as remote monitoring and remote control that traditional home appliances do not have. While continuously improving the intelligence and convenience of home appliances, they also provide the possibility of remote intrusion. For example, hackers make the alarm system invalid through intrusion attacks; or after mastering the control of smart home appliances through intrusion, they order the smart home appliances to run continuously, let them run at a higher power than the rated power for a long time, and even destroy them. [0003] In the existing remote control technology solutions for smart home appliances, due to the need for continuous data exchange, a large amount of plaintext data needs to be t...
