In this section, a summary of the entire “Anti-tamper Techniques to Thwart Attacks on Smart Meters” training module would be covered.  This summary would cover the “Detecting case tamper attacks using inductive switches “, “Detecting magnetic tampering using hall-effect sensors “,  and “Hardening a meter against magnetic tamper attacks “ sections of the training series. Links will be provided for the reference designs and design tools that were discussed during this training series.

Targeting the Test and Measurement application, this section includes many topics relevant to designing with SAR ADC devices.

The training provides a very comprehensive introduction of the commonly-used interfaces including RS-485, RS-422, ProfiBus, RS-232, IO-Link, CAN and LIN. These interfaces are used in the application of Factory Automation and some other industrial applications. For the engineer who needs to deal with interface system design, this is a very useful training.

This section covers what is meter tampering, why is this a problem for utility providers, and some common ways a meter is tampered.

Want to understand how high-voltage isolation technology works? Watch and learn about reliability testing for isolation. Filmed in TI's high-voltage lab, this series of videos will focus on capacitive isolation structure, working voltage reliability, withstand voltage capability, methods for testing reliability, and more.

In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.

Building automation system is a communication network infrastructure that manages the building service. This training will introduce the environmental sensor black diagram, key reference design and the solution for IC temperature sensor, power saving analog temperature sensor, digital temperature sensor … etc.

For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions.  Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.
