1.1 Use Cases

The ECC204 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.

The ECC204 device has a command set that allows for its usage in many applications. The primary uses include the following:

• Disposables and Accessory Authentication

  Authenticates that add-on accessories are authorized for use with a given host system. Both asymmetric and symmetric options can be implemented. Usage can be limited through the monotonic counter built into the device.

• Ecosystem Control and Anti-Counterfeiting
