Показать описание
When you need to ensure device or component authenticity and firmware version security, consider shared key authentication. This Chiptorial is your complete guide, walking embedded developers through every phase of implementing the symmetric shared key use case using Microchip's Trust Platform Design Suite (TPDS) software tool.

We use the SHA104 and SHA105 TrustFLEX secure authentication ICs from the CryptoAuthentication family that’s on the EV97M19A mikroBUS Evaluation Board that works in combination with the DM320118 CryptoAuth Trust development kit.

We'll explore the advantages and disadvantages, delve into cryptographic concepts, and show you how to set up your secure authentication using Microchip's key provisioning service.
