Micron Technology, Inc. introduced its new MT25Q NOR flash enabled with Authenta technology, providing content and command authentication to protect device functionality at the silicon level. This provides additional defenses to add enhanced trustworthiness for IoT devices, seamlessly expanding security to otherwise unsecured intelligent devices. High firmware integrity down to the lowest level of boot is critical today for connected devices used in a range of industries such as automotive, enterprise, industrial control and connected home. In addition to device security, Authenta technology allows new services such as secure over-the-air updates and additional services from edge silicon to cloud services.
As more devices, cars, homes and “things” are transformed by ubiquitous connectivity, the threat of cyberattacks continues to grow — especially with the rise of “always-on” internet connections. The new Authenta NOR flash trusted memory solution introduces a unique level of hardware-based security that not only enhances the integrity of the connected device itself, but also extends protection to the software that runs on the device, starting with the boot process. Moreover, Authenta NOR flash can easily replace the standard serial NOR flash used pervasively in the industry, enabling a unified approach to managing device health, functionality and updatability.
With trusted identity embedded at the hardware level and secure boot capability, Authenta technology allows connected devices to be authenticated directly with a host or secure gateway — whether in the cloud, at the edge or on the device. Micron MT25Q NOR flash combines these security features in a NOR flash solution that meets stringent quality requirements for automotive memory components in advanced driver-assistance systems (ADAS).

The MT25Q Authenta NOR flash is sampling now, delivering system-level enhanced cybersecurity for a broad range of connected devices. Customers can use this generation of flash memory the same way they have used standard quad-SPI NOR flash memory in past designs. All Authenta capabilities are powered by the upcoming Micron Key Management Service (KMS) that will enable a smooth hand-off of keys to customers or partners. Software development kits and partner solutions environments can be leveraged for additional resource savings and faster time to market.
