Microchip Technology CryptoAuthentication™ Devices
Microchip Technology CryptoAuthentication™ Devices offer hardware-based secure storage to effectively keep secret keys hidden from unauthorized users. These small, very-low-power IC 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 Microchip Technology 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.
Applications
- Cloud authentication
- Firmware validation
- Accessory authentication
- Intellectual Property (IP) protection
- Message encryption
- Asymmetric and/or symmetric key authentication
- Cartridge authentication to protect against cloning of consumable or disposable goods for consumer, cosmetic, industrial, and medical applications
CryptoAuthLib™ Library
Designed to work with Microchip Technology CryptoAuthentication and to simplify development, the CryptoAuthLib is a software support library written in C code. It is a component of any application or device driver that requires crypto services from the CryptoAuthentication devices. It works on a variety of platforms including Arm® Cortex®-M based or PIC® microcontrollers, PCs running the Windows® operating system, or an embedded Linux® platform.
