Abstract

The invention discloses a safe control method and system of equipment in a local area network and an apparatus. The method comprises the following steps: when first equipment in a local area network is running in a first safety-level mode, detecting whether the first equipment is attacked illegally; if detecting that the first equipment is attacked illegally, conducting secret key negotiation with a server to obtain a first authority secret key, and conducting encryption on interaction information between the first equipment and the server by applying the first authority secret key; and sending broadcast messages of running in a second safety-level mode to other pieces of equipment in the local area network, wherein the safety level of the second safety-level mode is higher than that of the first safety-level mode so that the equipment running in the first safety-level mode in the local area network is switched to run in the second safety-level mode. According to the method, interactivity among the equipment in the local area network is realized, other pieces of equipment can be effectively reminded once one piece of equipment is attacked, and thus the safety protection efficiency of the equipment in the local area network is improved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method, system and equipment for safely controlling equipment in a local area network. Background technique [0002] With the development of Internet technology, in many application scenarios, terminal devices can communicate in a local area network. For example, in a smart home application scenario, household air conditioners and other devices can communicate with related servers in a home local area network. [0003] However, in recent years, security incidents of smart devices have occurred frequently. For example, a smart car has been hacked due to the program, allowing the attacker to remotely control the vehicle, such as remotely controlling the vehicle to unlock, whistle, and flash lights. Therefore, how to improve the security protection efficiency of devices in the LAN has become an urgent problem to be solved. Contents of the invention [0004]...
