1.1 Use Cases

SHA106 is a member of the Microchip CryptoAuthentication family of high-security cryptographic devices that combine world class hardware-based key storage with hardware cryptographic accelerators to implement authentication.

SHA106 has a command set that allows for its usage in multiple symmetric key applications. The primary uses include the following:

• Accessory/Disposable Authentication

  Allows for authentication of accessory and or disposable system components. For disposable components, the use may be restricted through the use of a monotonic counter.

• Ecosystem Control and Anti-Counterfeiting 


  Validates that a system or component is authentic and came from the OEM shown on the nameplate.

In typical applications, the SHA106 will be used on the accessory/disposable side of an application and the SHA105 will be used on the host side of that application.
