X-Ware adds industrial-grade security to Microchip microcontrollers for IoT
Express Logic’s industrial-grade X-Ware IoT Platform now supports the TrustZone for ARMv8-M technology-based Microchip SAM L11 microcontrollers.
As device vendors open up their application programming interfaces (APIs) to share data and allow more interoperability within the IoT, information security and protection become significant issues, explains Express Logic. The X-Ware IoT Platform is powered by the ThreadX real time operating system (RTOS) and is claimed to provide a comprehensive and secure foundation that enables embedded developers using the SAM L11 microcontrollers to deliver more secure IoT devices.
“Next-generation embedded IoT products demand extensive security and efficiency,” said Bill Hutchings, senior product marketing manager for Microchip’s MCU32 business unit. “
Using the Arm TrustZone technology for Armv8-M with Express Logic’s X-Ware IoT Platform, developers can achieve new levels of security for IoT devices, claims Express Logic. The ARMv8-M architecture enables the ThreadX RTOS to partition the application into trusted and non-trusted memory regions. Application code in a non-trusted region is confined to that region and prevented from accessing any other region including the trusted region containing ThreadX.
ThreadX for Armv8-M is able to create and schedule multiple threads for both trusted and non-trusted regions. Application code running in the non-trusted regions can access the full ThreadX API, with the approval of the application’s trusted code. The trusted application can disable any ThreadX API from access by non-trusted code.
The X-Ware IoT Platform, ThreadX, FileX, and NetX Duo are certified to IEC 61508 SIL 4, IEC 62304 Class C, ISO 26262 ASIL D, EN 50128 SW-SIL 4, UL 60730-1 Annex H, CSA E60730-1 Annex H, IEC 60730-1 Annex H, IEC 60335-1 Annex R, and IEC 60335-1 Annex R, UL 1998, some of the highest levels of safety certification, says Express Logic.
Headquartered in San Diego, CA, Express Logic offers run-time solutions for deeply embedded applications, including the ThreadX RTOS, the NetX and NetX Duo embedded TCP/IP stacks, the FileX embedded FAT-compatible file system, the USBX host/device embedded USB protocol stack, and the GUIX embedded graphical user interface (GUI) development toolkit. All products include full source code and are available free of run-time royalties.
