The next generation of the LynxOS real-time operating system (RTOS) from LynuxWorks, LynxOS 7.0, is designed to enable embedded developers to add security functionality to their connected devices. The open standards-based LynxOS now adds significant new features to help meet the needs of the billions of next-generation connected devices.

Due to the ubiquity of the Internet, a network infrastructure is now in place for the “Internet of Things”—a new world of tens of billions of connected devices. The majority of those devices are expected to be hubs and sensor nodes, collecting data and transmitting it from machine-to-machine (M2M). Application examples include aerospace and defense communication infrastructure, industrial automation, smart meters, fleet management, device monitoring, medical and patient monitoring, and situational awareness.

With cyber threats becoming more sophisticated, and more of the critical infrastructure being controlled by these embedded devices, security protection will be required on each device rather than just relying on the network protection that is in place today.

LynxOS 7.0 provides the ability for developers to embed military-grade security directly into their devices by utilizing features such as access control lists, audit, quotas, local trusted path, account management, trusted menu manager and OpenPAM. It also contains networking support for long haul networks with TCP/IPV4, IPV6, 2G/3G/4G cellular and WiMax communication stacks. It also supports the short-haul networks common with M2M applications such as 802.11 WiFi, ZigBee wireless mesh and BlueTooth.

In many market segments, a more advanced communication mechanism will be required to offer extremely low latency, high throughput and high availability for application-to-application communications to help satisfy demanding real-time Quality of Service (QoS) requirements. LynuxWorks partners with key middleware providers such as Real-Time Innovations, Inc. (RTI) to offer these advanced middleware products ported on the LynxOS operating system.

LynxOS 7.0 is a deterministic, hard real-time operating system that provides POSIX-conformant APIs in a small footprint embedded kernel. LynxOS provides symmetric multiprocessing support to fully take advantage of multicore/multithreaded processors. LynxOS 7.0 includes new tool chains, debuggers and cross development host support. LynxOS 7.0 provides open APIs, including medium-assurance security per the general purpose operating-system protection profile (GPOSPP).

LynxOS 7.0 supports the most popular reference targets in the Intel and PowerPC architectures including the new Intel 4th Generation Core and the Freescale QorIQ processors. LynxOS 7.0 Board Support Packages are available for targets from GE Intelligent Systems, Curtiss Wright and Extreme Engineering.
