IoT Protection with MCU Security - Ward Off Attacks with Trust Zones, Encryption, Secure Keys and Tamper Detection

Security breaches jumped 107 percent as malevolent forces increasingly focused on IoT devices for side attacks, IP and data theft. Semiconductor vendors supplying on-chip cryptography, memory protection, unclonable technology, random number generation and other measures hope to shut the door on attackers.

In the summer of 2024, the Internet of Things is under attack and microcontroller suppliers are responding with hardware-based security measures designed to prevent them. Whether its is an attack on data, intellectual property or a side attack using a $15 modified probe, malevolent forces are seeking ways to crack the code, breach the fortress and break the chain.

Are the security measures that semiconductor companies list on publicly available datasheets adequate to prevent the next wave of breaches, cloning, ransomware and malware? Or are attackers devising new ways of getting through a battery of defensive measures as IoT becomes more ubiquitous in deployment?

Whatever the case maybe, it's clear that MCUs are the focal point of such attacks.
