Systems with replaceable or limited life sensors, peripherals, modules, or consumables are commonly targeted by unauthorized aftermarket companies. These counterfeit replacements can introduce safety concerns, reduce quality, and negatively impact OEM revenue. With DeepCover® secure authenticators, a cryptographic solution can easily be implemented for any system where digital processing capabilities exist. With over 3.2 billion secure authentication units shipped, we are experts at helping you implement hardware-based physical security to achieve low-cost counterfeit protection, peripheral device authentication, secure feature setting, and more.
