Abstract

A method for encrypting rolling code of a digital key for a vehicle performs a three handshake matches between a key transmitter and a vehicle receiver, thereby eliminating mask theft to obtain the rolling code because the two need to perform multiple matches such as time matching and device ID matching. This improves the safety of the rolling code without adding new codes or designing new encryption programs, thereby improving safety while reducing usage costs.
