2.2 Anti-tamper Techniques to Thwart Attacks on Smart Meters—Detecting case tamper attacks using inductive switches: Designing PCB Inductors and Selecting a Target Metal

Details

Date: April 12, 2017

The LDC0851 inductive-based case tamper detection implementation compares the inductance of a reference coil and a sense coil to determine a case tamper event.  The reference and sense coils can be created by fabricating the coils onto a PCB.  This module covers how to create these PCB inductors using WEBENCH and how to optimize the resulting coils.  In addition, details on how to select a target metal would also be provided in this section. 

This is the second of three modules for the “Detecting case tamper attacks using inductive switches” section of the “Anti-tamper Techniques to Thwart Attacks on Smart Meters” training series.
