In general terms, authentication is proving that a device or object is what it is purported to be. For example, proving that the battery pack for this battery powered tool is genuine or authentic is a key element to any robust security solution. Failing to implement an authentication scheme using a hardware security ICs significantly increases the change that the product or component will be cloned. If a cloned or unauthorized client is installed and used, the OEM, and possibly the end user, may be at significant risk. Cloned products or components can negatively impact an OEM’s revenue, brand image, and may lead to liability exposure.
