Micron, Microsoft team up on IoT cloud security

April 25, 2017 // By Peter Clarke
Memory chip maker Micron Technology Inc. is collaborating with Microsoft Corp. by combining its Authenta technology with Microsoft's Azure cloud software.

The combination will provide trusted computer models for IoT deployments in industrial, automotive and consumer applications, Micron said.

The Authenta technology utilizes a hardware "root of trust" integrated into flash memory in the IoT leaf node and in the Microsoft Azure IoT cloud to establish a trusted link between that IoT device and the cloud.       

Microsoft has itself been focusing on security and recently tipped research into a minimum hardware configuration for secure MCUs (Microsoft ready to share secure MCU).

Authenta makes use of Device Identity Composition Engine (DICE), an upcoming standard from the Trusted Computing Group (TCG), to ensure that only trusted hardware gains access to the IoT cloud. A range of IoT nodes that use standard flash memory chips can now be enhanced to improve cyber-security using this approach.

Authenta is initially available in the Micron serial NOR product family and is sampling now to select customers.  Users of Microsoft's DICE technology and Azure IoT services can now contact Micron and Microsoft to begin evaluation and integration of these security and identity solutions.

In addition to the hardware, Microsoft and Micron today announced that they will offer software development kits (SDKs) to support authoring secure IoT cloud management and connectivity for new platforms and devices and the ability to retrofit legacy systems.
