No remote orchestration infrastructure is provided. This general-purpose configuration specifies four virtual machines that are each allocated a dedicated CPU core, and the LynxOS-178 RTOS guest is loaded into each virtual machine. Lynx Software Technologies Announces Appointment of Michel Genard and For example, we have a how-to for x86 that describes how to digitally sign your LynxSecure SRP binary and add keys to the BIOS to enable secure boot.Following the signed SRP, secure boot can be continued using the LynxSecure segmented boot feature. Firstly, LynxSecure runs Initial built in test (IBIT) and continuous built in test (CBIT) to validate the crucial hardware registers that control the partitioning of the system remain valid. Does Lynxs RTOS possess the ability to support segregation of data and processes of differing security classifications? Once loaded into memory, the first stage bootloader will jump to and hand-off control of the system to LynxSecure. You change the start-up script to call your application instead of bash, leaving you with a system with just the minimal necessary components, and hence less expensive to certify. No. However, this will likely require that a comprehensive RTOS BSP is available. In May 2014, the company changed its name to Lynx Software Technologies. Does Lynxs IPv6 software stack have to be used in conjunction with LynxOS-178? The reuse of APIs that exist on LynxOS-178 (FACE, POSIX etc) provide an opportunity for customers to migrate existing applications to LynxElement. Are any of Lynxs products subject to ITAR? It is the location where applications are stored before they are loaded and executed (automatically at startup) by the RTOS. Short answer: Lynx offers a NIST 800-53 package for LynxSecure, the current NIAP-supported certification and accredited process for critical systems. [5], A modular software development framework, the framework allows developers to design and integrate multi-core safety and security systems for industries such as the avionics, industrial, automotive, and UAV/satellite industries. Unikernels can provide APIs (Lynxs product supports POSIX for example) which makes it simpler for developers to build applications. VLANs are represented as separate LCS network interfaces and identified as interface-name.VLAN-ID, e.g eth0.100, consistent with Linux and UNIX systems. Active, Closed, Last funding round type (e.g. Evaluation versions of our products can be requested, Command line modeling tool LSKs autoconfig, Luminosity Eclipse-based IDE for LynxOS-178 and Buildroot Linux development -, Command line tool chains based on GCC/GDB for both LynxOS-178 and Buildroot Linux, FreeRTOS support GCC/GDB support (pending). LynxSecure was designed to satisfy real-time, high assurance computing requirements used to regulate military and industrial computing environments, such as NIST, NSA Common Criteria, and NERC CIP. The flow resembles that of DAL A but tends to include artifacts that are specifically owned and generated by the aircraft company themselves. CREATE_BUFFER and SEND_BUFFER are Buffer Services service requests, Blackboard Services: A blackboard is a communication object used by processes of the same partition to send or receive messages. There are about 60 audit events. is in reference to the boards native, power-on firmware and bootloader for the system, i.e. LynxSecure has no role in copying or moving data from user to supervisor to user privilege modes. Why did Lynx decide to harness LynxOS-178 as the foundation for its unikernel offering? Lynx Software Technologies - Products, Competitors, Financials Watchdog: guests can be configured to strobe a virtual watchdog timer that the separation kernel will monitor. (Really!) LynxOS-178 and LynxOS-SE provide the following system service groups in accordance with the ARINC 653-1 standard: ARINC 653 partitions are always enabled in LynxOS-178, but by default everything is in a single partition. LynxOS-178 satisfies the PSE 53/54 profiles for both dedicated and multi-purpose real-time as well as FACE applications. VLANs are implemented by adding a VLAN Identification (ID) TAG into the Ethernet packet header. TIMED_WAIT and PERIODIC_WAIT are Time Management service requests. Individual applications can have dedicated encryption modules assigned to the edge of the application interface to decrypt data reads and encrypt all data writes before passing the data to the RTOS filesystem to complete persistent block device commits, Partition Layer Individual drive partitions can be separately encrypted by a software encryption layer that can transparently decrypt/encrypt data read and write requests performed by individual application partitions, Block Device Layer Full disk encryption is supported through the integration of SED (Self Encrypted Drive) with the Lynx RTOS hardware control interface. ARINC 653 Health Monitoring: The Health Monitor (HM) is invoked by an application calling the RAISE_APPLICATION_ERROR service or by the OS or hardware detecting a fault. What can LynxSecure offer? The Luminosity embedded development tools suite from Lynx offers powerful development, debug and analysis tools integrated into an Eclipse-based environment for maximum interoperability. Once the SoC has an accurate PTP clock, PCI BAR sharing is used to give other VMs access the timer registers. Software cache-coloring is not supported today.Read blog post: Multicore Cache Allocation Technology (CAT) Demo, The LYNX MOSA.ic framework and architecture allows customers to deploy their favored network protection solution within the guest OS that they prefer and have consequently assigned with the necessary hardware privileges and security policies. There is a LynxSecure demo where a VM is given access to an encrypted storage area and a Yubikey USB digital key to unlock it and provide secure access to control a robot via IPC (FIFO). Is Lynx actively working on multicore designs for systems requiring certifications? It implements POSIX.1-2008 (2016 Edition), which is POSIX's core functionality, POSIX.1b (the POSIX real-time extensions), and POSIX.1c (also known as POSIX pthreads extensions). All application-specific system calls are pushed as close to the app as possible. This is because some software is required to set up the hardware (establish permissions as to what system resources can be accessed by the unikernel, as one example). Our MfA 2021.11.2 integration is with GNAT Pro Ada 21.6 from Adacore. clusk@stantonprm.com, Internet Explorer presents a security risk. The CodeSonar tool allows tunable coding rules to be applied as appropriate to the code base of interest. The specific variant is a Fanless ruggedized version featuring a 4 core, 8 thread Core i7 processor from Intel, 16GB Memory a 512GB SSD and 2 NIC cards. [19] LYNX MOSA.ic's modular structure allows users to isolate computing resources into self-managed independent environments. Partition level authentication is achieved in the hypervisor through the monitoring of system management calls. First, Buildroot embedded Linux is included with MOSA.ic as a pre-integrated guest OS. The privileged setup code is discarded (for security) so that all that is left of LynxSecure is a set of event handlers to respond to and redirect interrupts and handle management calls like shutdown. In July 2021, Lynx also partnered with Collins Aerospace, providing LYNX MOSA.ic for Avionics as the foundation for Collins Aerospace's Perigon flight computer. A maximum of 4095 VLANs per trunk interface are supported. How could LYNX MOSA.ic be configured for a Line Replaceable Unit (LRU) application? For secure systems, a type-1 hypervisor (where no underlying helper OS is present) that runs directly on hardware and loads virtual machines should be used. Would have great skills in front end technologies (JavaScript, Angular, Typescript, NodeJS, etc.) It is deliberately minimal (no console, no create-VM APIs, no login). This general-purpose configuration specifies four virtual machines that are each allocated a dedicated CPU core, and the LynxOS-178 RTOS guest is loaded into each virtual machine. The exception to ITAR related to Lynx products and services is if a board that software is ported to is a U.S. Government proprietary board. Luminosity offers a modern interface based on open standards, giving a consistent user experience across the Lynx Software Technologies family of real-time operating systems. Stonepine Advisors, LLC served as financial advisor, and DLA Piper LLP served as legal counsel to Lynx. No one company can deliver all technologies for the next generation of securely-connected mission critical platforms. Lynx delivers documentation associated with each Stage of Involvement (SOI) milestone involved in reviewing a system or sub-system. Developers can however choose to emulate this approach by assigning all key system functionality to a guest OS of their choice. Data and process segregation of security classification is fully supported through the underlying hypervisor used to physically partition resources and map segments of resources to authorized applications. Using the Xilinx bootgen utilities (pat of SDK), the LynxSecure image was processed to create a signature of Separation Kernel and guest images. Each system management call is handled by the hypervisor which contains the access control policy encoded as a permission lookup table created during the system build process. Seed, Series A, Private Equity), Alternate or previous names for the organization, Whether an Organization is for profit or non-profit, General contact email for the organization. What is the relationship between Lynx and Lynuxworks? It stipulates the following: Lynx products and services are not subject to ITAR. Lynx Software Technologies - Resources - FAQ Does Lynx provide a certified IPv6 stack?

[15], LYNX MOSA.ic is built on Lynx Software Technologies' LynxSecure separation kernel hypervisor, which helps isolate applications and manage critical system assets. For additional information, contact us at inside@lynx.com. CPUs dont move the bits in a DMA transaction. Yes. Each region is zero copy from the perspective of the Separation Kernel. Based on the popular Eclipse IDE framework (see question and answer above), Luminosity is a full-featured Java-based IDE for all Lynx cross-development platforms. What are the main differences between an operating system and unikernel? ), C and C++. Lynx Software Technologies - Wikipedia It's available for users with the operating system Windows 2000 and previous versions, and it is available in . The intention is this Unix-like command line setup is used for development. LynxSecure is not an RTOS and it relies on fine-grain privileged operating systems to use the software stack selected by our customers for each purpose.Customers using LynxSecure have created upgrade mechanisms which are platform or SoC specific solutions customized to their needs. Hands on experience with Git Gradle Maven Ability to learn and implement newer QA technologies and optimize existing processes. For a more complete listing of our RTOS-related resources, visit our. LynxOS-178 drivers are separate binaries that are loaded at boot time. Both our RTOS, LynxOS-178 and bare-metal target environments are built with the GCC compiler, additionally Lynx uses the GDB debugger and the Eclipse IDE. We are engaged with several semiconductor companies under NDA to understand their RISC-V based product plans. We have a how-to for x86 that describes how to digitally sign the LynxSecure binary and add keys to the BIOS to enable secure boot. By design it should be impossible to programmatically change these, so CBIT is intended for things like single-event upset (SEU), ie cosmic rays, but it also protects against a hw faults or weakness (like rowhammer). The Eclipse open source community was started in 2001 when IBM released the Eclipse Integrated Development Environment (IDE) as an open source development framework for Java and other languages. All security policies, hardware partitioning, and inter-guest memory access privileges are defined according to the engineers needs, with few design impositions due to the hypervisor. GET_PROCESS_ID and GET_PROCESS_STATUS are Process Management service requests, ARINC 653 Time Management: services related to time management. Proven strong problem-solving skills, troubleshooting, and root cause analysis. We are open to discussions for other silicon chips provided they include hardware virtualization support. Second, Linux is helpful as a configuration, prototyping or debugging aid. Have used technologies that enabled testing, deploying and validation of the code. Bosch VHIT (Italy) Partners with Lynx Software Technologies - GlobeNewswire For every architecture, LynxSecure defines one or more shared memory regions between guest operating systems.Each region is uni-directional/single-write.Each region is zero copy from the perspective of the Separation Kernel. This means Buildroot Linux is easily deployed in one or multiple virtual machines in your design. By design it should be impossible to programmatically change these, so CBIT is intended for things like single-event upset (SEU), ie cosmic rays, but it also protects against a hw faults or weakness (like rowhammer).Secondly, LynxSecure has an audit log. The VGA usecase allows a physical graphics card to be shared so that multiple VMs can have their own (reduced size) framebuffer and share the screen. Gurjot Singh - Board Member - Lynx Software Technologies - LinkedIn Both enable remote 3rd party creation of binary payloads to be loaded and executed on the target. Lynx Software Technologies - Funding, Financials, Valuation & Investors On x86 there is a modulea bare-metal virtual machine (VM)called LSAstore that intercepts a block device (disk or partition) and provides transparent encrypted disk storage. These include resource partitioning and time partitioning tests which are specifically designed to ensure adherence to the ARINC653 standard. Can you share more details about the Ethernet support included in LYNX MOSA.ic? The diagram below shows an example of a general-purpose LYNX MOSA.ic system configuration to provide clarity on how the BSP is composed to support the target system requirements. Modules can be inserted as source libraries linked against standard POSIX and ARINC IPC interfaces or binary appliances connecting to virtual ethernet or virtio component interconnects. But, in general, LynxSecure does NOT contain any certified cryptographic libraries. hbspt.cta._relativeUrls=true;hbspt.cta.load(4385221, 'd16929a7-5c94-41a1-9483-55cc11b23090', {"useNewLoader":"true","region":"na1"}); 2023 Copyright Lynx Software Technologies | The information herein is subject to change at any time after the date of publication. All system management calls are logged in a protected security log buffer.

VLAN and Time Sensitive Networking (TSN), IEEE 802.1AS, time-aware shaper (IEEE 802.1Qbv) and credit-based shaper (IEEE 802.1Qav) are supported in MFA 2022.12. That is, the hwtimestamp capability, which is how PTP and 1588 work, is only available in the NICs PF (physical function).IEEE 1588 (PTP) lets you synchronize clocks over a LAN. It is the only Commercial-off-the-Shelf (COTS) OS to be awarded a Reusable Software Component (RSC) certificate from the FAA for re-usability in DO-178B/C certification projects. MfA provides 2 containerization options that may be used independently or in concert. 20 comments Add a Comment [deleted] 3 yr. ago Lynx is a reseller of Interactive Brokers. Safety Evidence Assurance Level (SEAL) is the acceptable means of compliance that the US Government uses for military aircraft including the Joint Strike Fighter (F-35). As a POSIX RTOS, a filesystem is mandatory. It is important to note that for every device assignment, the hypervisor guarantees that the impact of hazardous events created by devices such as erroneous DMA and interrupt pre-emption, is constrained to the VM assigned to the device, protecting the integrity and timing of the other VMs. Lynx Software Technologies, Inc. The completion of this transaction marks the beginning of an exciting new chapter for Lynx, and we look forward implementing our engineering-like approach to value creation and pursuing strategic growth initiatives in partnership with the management team..
