Protect Your MCU Design from Copying and Reverse Engineering
MCUs are used as the main control element in just about every application imaginable. Their power and flexibility make them the go-to component at the heart of most designs. Since it is important to make sure that your design cannot be easily copied, reverse engineered or tampered with, modern MCUs now provide a few different options for protecting your design; a good understanding of the capabilities and trade-offs are important in order to determine which approach is best for a given design.
This article will review some of the common approaches to design protection, such as making your MCU unreadable from the outside world, using on-chip capabilities to validate that the code to be executed is unmodified, and using external components to provide more advanced security capabilities. On-board techniques for tamper detection and possible “penalties
