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
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.
