Our CryptoAuthentication™ devices offer hardware-based secure storage to effectively keep secret keys hidden from unauthorized users. These small, very-low-power devices work with any microcontroller (MCU) or microprocessor (MPU) to provide flexible solutions for securing Internet of Things (IoT) nodes used in home automation, medical devices, wearables and many other applications. They can also be used to protect the authenticity of consumables and accessories, ensuring that only legitimate ones work with your product and preserving your revenue stream.
The optimized architecture of our CryptoAuthentication ICs is composed of hardware-based cryptographic accelerators to significantly reduce execution time and power consumption. A high-quality random number generator and EEPROM-based secure key storage are also embedded inside these devices. To provide extra security, they also come with physical anti-tampering and side-channel attack protections to block access to embedded system credentials.
