Trusted MCUs for IoT applications

As IoT technology continues to make our lives more comfortable through greater intelligence enabled by networking smart devices, it becomes increasingly important to protect the information stored and transmitted by these devices. Embedded MCUs are at the core of IoT-based products, and selecting the right MCU is key to meeting the present and future needs of your customers. An MCU designed for IoT applications needs to have sufficient processing capabilities, hardware-based security, and software algorithms to provide a safe and secure solution. Secure MCUs should offer multiple levels of security elements to support various security algorithms like Advanced Encryption Standard (AES), Data Encryption Standard (DES), and Secure Hash Algorithm (SHA). The MCU needs to provide a complete chain of security, secure boot process, hardware-based root of trust, true random number generation functionality in hardware, and user application code authentication, among other capabilities.
