Title:
PROTECTION METHOD, SMART LOCK, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/029920
Kind Code:
A1
Abstract:
The present application relates to a protection method, a smart lock, and a computer readable storage medium. The method confirms a smart lock is subjected to an electromagnetic attack (for example, a high-voltage electromagnetic attack) by means of a two-level detection mechanism; one level of the detection mechanism considers the smart lock is subjected to a suspected attack by means of detecting that a number of trigger events is greater than or equal to a first preset value in a first period; when the first level of the detection mechanism detects a suspected attack, the second level of the detection mechanism acquires multiple light intensity values and detects that an amplitude of change amplitude of the light intensity values exceeds a preset threshold within a preset duration, thereby confirming the intelligent lock is subjected to an electromagnetic attack (for example, a high-voltage electromagnetic attack). After the two-stage detection mechanism confirms that the smart lock is subjected to an electromagnetic attack, the smart lock enters a protection mode for active protection, thereby preventing false unlocking, and simultaneously protecting each peripheral device from being damaged, thereby increasing security.
