Title: METHOD AND DEVICE FOR DETECTING A RELAY ATTACK
Abstract:
The invention relates to a method for detecting and preventing a relay attack on a transaction that can be carried out by means of contactless data transfer between a data carrier (10) and a terminal (20). A transaction signal transmitted by the data carrier to the terminal in order to carry out the transaction comprises supplementary information, which enables the terminal to detect a relay attack. The transaction can relate in particular to the unlocking of a motor vehicle.
