Introduction

The SHA104-TFLXAUTH is a member of the Microchip Technology Inc. Trust Platform product family. The device is a pre-provisioned SHA104 targeted for symmetric authentication applications and is ideally suited for consumable and disposable applications. The device can be used in systems where either the host can assist in the authentication by way of a challenge-response pair or, for more security, can be used with a host-side security device to perform a CheckMAC operation. The SHA104-TFLXAUTH can be paired with the SHA105-TFLXAUTH or other Microchip CryptoAuthentication™ host-side devices.
