Green Hills' INTEGRITY RTOS selected by Keri Systems for building security system

EDP Weekly's IT Monitor, March 21, 2005

Green Hills Software, Inc., a leader in embedded software development tools and real-time operating systems, has announced that its INTEGRITY real-time operating system (RTOS) has been selected by Keri Systems for use in its Access Control Device, a multiprocessor platform which securely manages personnel access to single- or multi-building complexes using card readers, number pads, fingerprint analysis and more. Green Hills Software is also providing the MULTI development environment and optimizing C compilers for the secure systems.

"We chose INTEGRITY because of its extraordinary security," said David Miller, Senior Systems Engineer at Keri Systems. "In addition to secure partitioning, we needed an advanced RTOS that could meet our stringent requirements of zero down time. For our customers, failure is not an option. INTEGRITY was the only RTOS that could handle the job."

Configured using its Access Control System Software, Keri Systems' line of access controllers manages access into buildings and into interior areas of buildings. These access control devices represent the latest technology in the industry for access as well as for cataloguing personnel movement throughout a building site. The INTEGRITY RTOS will securely manage communications between the system control center and nodes (entry sites) throughout a building. SSL is being used to provide secure communications over an Ethernet network.

"Keri's selection of INTEGRITY over other real-time operating systems for its Access Control product line validates the leading high-availability architecture and real-time responsiveness of the INTEGRITY RTOS," said David Kleidermacher, vice president of engineering at Green Hills. "Only a memory-protected, partitioned RTOS with fast, predictable response times can deliver the security needed for a high-reliability access control system like Keri's."

At its core, the INTEGRITY microkernel design and advanced partition scheduling technology enable it to meet the demanding performance, reliability and security requirements of modern safety- and security-critical systems such as the Keri Access Control System. The robust partitioning architecture of the INTEGRITY RTOS, which is royalty-free and POSIX certified, guarantees that critical tasks have the resources they need to run correctly. In addition, both the operating system and user tasks are protected from errant and malicious code, including denial of service attacks, hackers, worms and Trojan horses.
