It can be a very hostile world for electronic equipment to operate within. 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. Similarly, with relentless attacks and serious consequences for breaches, the security requirements for medical and industrial IoT products have never been more important. With DeepCover® secure authenticators, a cryptographic solution to eliminate these issues can easily be implemented for any system.
With over 4 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.
