Security: the key to success for MCU-based IoT applications
As the Internet of Things (IoT) expands, there is growing concern over how to safeguard the massive amount of data transmitted and stored by IoT devices. MCUs that support standard encryption, decryption, and authentication algorithms can help mitigate concerns about data security. It is also increasingly important to protect IoT devices from tampering that can reveal important security information, such as security keys, to defeat security measures. MCUs that support code protection, tamper detection, and other advanced security capabilities can defend devices from these types of invasive attacks.
This article will quickly review the key security capabilities of MCUs you should look for in IoT-oriented designs. Once you understand some of the common capabilities you can better look for the implementation that will offer the best fit for your next design. Some example security-oriented devices will be described to better illustrate the use of key security features in IoT applications.
