The element14 ESSENTIALS of IoT Security covers the fundamentals of IoT security, including types of security threats, standard security algorithms, error correction, cryptography, and security from end-nodes through applications. To extend the knowledge covered in the main module, this supplementary guide discusses the types of related components or development boards available for prototyping new products or building projects.
Secure Element
The A71CH is a ready-to-use solution providing a root of trust at the IC level. It is a platform capable of securely storing and provisioning credentials, securely connecting IoT devices to cloud services, and performing cryptographic node authentication. The A71CH solution provides basic security measures protecting the IC against many physical and logical attacks. It can be used with various host platforms and host operating systems to secure a broad range of applications.
