Application Note: Using Symmetric Authentication to Validate a Credential or Device
Check out this application note to learn about how to determine whether a device is authentic or authorized by validating its credential (a Datakey CryptoAuthentication memory token) using Symmetric Authentication. The application note explains what Symmetric Authentication (aka Symmetric Key Authentication or Symmetric Encryption) is and explains common terms like challenge, nonce, digest and more. It walks through the process step-by-step and even calls out which functions in Microchip's CryptoAuthLib library to use for each step.
Getting Started with CryptoAuthentication through Microchip's Quick Start Lab and Video
Datakey CryptoAuthentication memory tokens work with Microchip's development boards and tools, including Microchip's Quick Start Lab that covers:
- Symmetric Authentication of a Remote Device
- Asymmetric Authentication of a Remote Device
- Asymmetric Authentication Using Certificates
- Configuring the ATEECC608A
This resource tells you everything you need to get started and includes a video showing how to get everything set up for the labs.
