Boeing adopts MILS architecture for enhanced system security.
Multiple Independent Levels of Security (MILS) is a high-assurance security architecture that is based on the concepts of processing separation and controlled information flow. MILS allows for independent evaluation of security components and trusted composition, and uses one or more separation techniques to assure that data at different security levels on different partitions can only be accessed as defined and configured in system security policies. Boeing has adopted the MILS architecture for Distributed Systems based on Real-Time Innovations' (RTI) DDS compliant integration infrastructure and Wind River's separation kernel platform, the VxWorks MILS Platform 2.0.
The VxWorks MILS Platform allows a single processor to host applications running at multiple security levels (for example, secret and top secret), reducing space, weight and power requirements compared to the traditional approach of segregating security levels across different processors. RTI Data Distribution Service complements the VxWorks MILS Platform by enabling applications running in different secure partitions, or on different processors, to easily communicate and share data using the Object Management Group (OMG) Data Distribution Service for Real-Time Systems (DDS) specification.
Boeing has incorporated the RTI and Wind River MILS solution into its own embedded platform. This is the first time a DDS implementation has been shown to function on a MILS separation kernel platform, providing Boeing designers with a standards-compliant, distributed computing and application integration solution.
“We’re pleased to be working with Wind River in delivering this MILS solution,” explained Stan Schneider, CEO of RTI. “The ability to securely exchange data in real time across separate address spaces on a single platform enables better use of processing resources in environments where space and weight are at a premium.”
RTI Data Distribution Service is a messaging and data-caching solution for the development and integration of applications that require low latency, high throughput, high scalability, deterministic responses and minimal consumption of network, processor and memory resources. RTI Data Distribution Service meets the requirements of mission-critical, real-time systems, including the ability to run in dynamic and autonomous environments and over unreliable or low-bandwidth networks such as wireless and satellite links.
RTI Data Distribution Service complies with the OMG DDS Application Programming Interface (API) standard and with the DDS wire interoperability standard, the RTPS protocol.
