Introduction

The SHA106 is a member of Microchip Technology Inc. CryptoAuthentication™ product family used in accessory or disposable applications. The device is a parasitically-powered Single-Wire Interface (SWI) version of the SHA104. The device provides 128-bits of symmetric security targeted for disposable and ecosystem control applications and is intended to be used as a companion device and is microcontroller/microprocessor agnostic. The device can be used in systems where either the host can assist in the authentication through the use of a challenge-response pair or, for more security, can be used with a host side security device to perform a CheckMAC operation. The SHA106 can be used in conjunction with the SHA105 or other Microchip CryptoAuthentication host side devices.
