AuKey MCU

STMicroelectronics rolls the AuKey turnkey solution based on ST's ST23 highly secure microcontrollers targeted to to help brand owners authenticate their products. AuKey provides significantly stronger security than conventional techniques, which are often susceptible to being easily and cost-effectively broken or cloned. AuKey suits various products, including computer accessories, add-in cards, gaming peripherals, printer cartridges, toners, disposable medical equipment, network infrastructure products, metering devices, and many other types of assemblies and systems.

Product authentication using secure MCUs is significantly more effective in differentiating genuine items from unauthorized copies. ST's AuKey turnkey solution offers hardware-authentication devices comprising a secure OS running on top of the latest-generation ST23 secure MCUs to increase protection for the embedded security keys.

The most advanced security crypto algorithms are supported by AuKey, including the AES shared-key system and Elliptic Curve Cryptography. The MCU and OS, together, also secure the chip's data-read and data-write mechanisms. This level of protection delivers a significant increase in security at a highly competitive cost.

This approach differs from conventional security methods, which rely on a relatively simple memory chip containing the security keys. Organized counterfeiters have learned to break this level of security, presenting a threat to brand owners' image and revenues. Counterfeit products, most of which will perform poorly, will also increase downtime, maintenance and replacement costs for end users.

AuKey's secure MCU-based security also provides freedom and flexibility for brand owners through its customizable security architecture, configurable key-management mechanism, and chip-personalization tools. Also, support for secure application firmware downloads allows authorized updating or restoration of settings in the field.

AuKey is based on ST's range of proven ST23 highly secure MCUs, which are in full production now and are packaged in the industry-standard SO-8 format.
