This invention discloses an encrypted communication method and storage medium for an active system, applicable to the field of communication technology. During encrypted communication between the active controller and the receiving glasses, the active controller sends a dog-feeding array within a specific time period of one transmission cycle of the left and right eye opening / closing control signals, rather than sending the array throughout the entire transmission cycle.

This process primarily increases the difficulty of security verification by transmitting the dog-feeding array within a specific time period, thereby improving the security of encrypted communication between the active controller and the receiving glasses to a certain extent.
