Green Hills Debuts IPv4/IPv6 Stack for Safety-Certifiable INTEGRITY-178B RTOS

11/5/2004 - Green Hills Software, Inc., the market leader in safety-critical and royalty-free real-time operating systems (RTOS), announced the immediate availability of two dual-mode IPv4/v6 Internet Protocol stacks for its RTCA/DO-178B, Level A compliant INTEGRITY-178B RTOS for safety- and security-critical applications. The IPNET and IPLITE stacks take advantage of the INTEGRITY-178B RTOS’ secure partitioning, allowing networked applications to share the same processor as software requiring certification to the most stringent safety standards.

Developed by Green Hills Software’s technology partner Interpeak AB, the IPNET and IPLITE protocol stacks provide backward compatibility with current IPv4 requirements while overcoming IPv4’s security shortcomings and 32-bit address limitations.

“More and more safety-critical systems are requiring sophisticated networking support alongside software that complies with the highest levels of assurance for safety and security,” said Dan Mender, director of Business Development for Green Hills Software. “These systems require a highly reliable and trusted operating system like our INTEGRITY-178B RTOS and a complete, integrated networking solution. Soon IPv6 will be a common requirement in airborne systems as well as many other safety- and mission-critical systems.With our Interpeak partnership, INTEGRITY-178B developers can build products today that will thrive in the expanded IPv6 Internet environment of the future.”

“Next-generation networked devices will have to contain IPv6 capabilities due to requirements for increased security and new IP addresses,” added Johan Fornaeus, chief executive officer of Interpeak AB. “Our dual-mode protocol stack technology, together with the INTEGRITY-178B RTOS and its unique protection features, creates a powerful IPv4/IPv6 networking solution that is ready for the robust communications needs of secure and reliable embedded devices.”

IPNET provides complete IPv4 and IPv6 networking solutions, supporting multiple network interfaces, NAT, PPP, built-in routing tables, VLAN tagging, Quality of Service and built-in advanced IP Security (IPsec). IPLITE provides a small and compact dual IPv4/v6 protocol stack configurable from 17 KB of memory for embedded systems requiring a small footprint. IPsec is optionally available for IPLITE.

Both stack offerings have additional network applications available such as Telnet, FTP, TFTP, DNS and DHCP, along with L2TP, LDAPc, NAT, PPPoE, RIPv2, SNTP, Web server, secure Web server, MobileIP and SNMPv1/2c/3. Additional security protocols such as Radius, Firewall, SSH, SSL and IKE are also available.

Both IPNET and IPLITE are fully compatible with existing Internet standards, facilitating seamless support for both IPv4 and IPv6. This enables INTEGRITY-178B users to deploy IPv4-compatible systems today that are ready for IPv6, while retaining their investment in development tools, RTOS experience and application interfaces.

IPNET and IPLITE run seamlessly in an INTEGRITY-178B protected virtual address space.

The INTEGRITY-178B RTOS is targeted for the aerospace and defense industries, where today’s avionics, vetronics and vehicle management systems must comply with the most demanding requirements for safety and security. It is a robustly partitioned, hard RTOS that has been designed and developed from the ground up to safeguard applications that operate at the highest levels of safety and security classification, protecting them from the most catastrophic safety hazards and malicious security threats.

The INTEGRITY-178B RTOS has become the most frequently selected operating system for safety-critical and mission-critical applications, where system reliability, data integrity and security are paramount and fast, predictable response is required. The INTEGRITY-178B RTOS provides complete time, space and resource protection between multiple applications operating on the same hardware platform. This partitioning effectively builds a firewall between applications executing in different virtual address spaces and the kernel, preventing errors in one application from corrupting other applications or the kernel. An INTEGRITY-178B partition cannot accidentally or maliciously affect another partition’s code, I/O or data.

The INTEGRITY-178B RTOS is available now with RTCA/DO-178B, Level A certification data, the robust MULTI/AdaMULTI development environment and Green Hills Software’s EEMBC benchmark-leading compiler family.
