DDC-I and wolfSSL have a new partnership that has established the availability of the wolfCrypt cryptography library and certification kit, certifiable to DO-178C Level A, for DDC-I’s Deos real-time operating system, which can support the development of cockpit display applications such as the one pictured here.

Avionics developers are now able to use military level, safety-critical cryptography to deliver secure communications through DDC-I’s Deos Real Time Operating System (RTOS).

DDC-I, a global supplier of real-time operating systems, and woflSSL, a TLS cryptography provider, have made a cryptography library and certification kit certifiable to DO-178C Level A, according to a Sept. 21 press release. This means avionics developers will have a commercial off the shelf (COTS) product that meets federal information processing standards, FIPS 140-2, and can be used to support safety-critical RTOS applications.

“The integration of Deos and wolfCrypt should prove very attractive to avionics developers who require a secure, out-of-the-box, safety-critical solution that comes ready to certify, complete with DAL A evidence,” Larry Stefonic, CEO and Founder at wolfSSL, said in a statement. “We have a very strong working relationship with DDC-I and find Deos to be quite straightforward to work with. Together, I believe we offer our joint customers a world-class platform that features best-in-class RTOS and security.”

According to DDC-I, Deos can be used in air data computers, air data inertial reference units, cockpit video, displays and instrumentation, flight management systems, and engine management.

“Deos is a safety-critical RTOS that is inherently secure with its time and space partitioning and its safety-critical architectural design, and any customers that require extended security features can now leverage the collaboration between DDC-I and wolfSSL to support their security needs,” Greg Rose, Vice President of Marketing and Product Management at DDC-I, told Avionics International.

Some encrypted systems require security packages to communicate with each other, the integration with wolfCrypt would facilitate that connection, Rose said. Avionics or ground systems that require "Secure boot, Secure Update, and Secure Communications" would be able to use this encryption, according to DDC-I.

Together, Deos and wolfCrypt, can be used for anything from military systems to Urban Air Mobility or avionics systems featured on commercial airliners. DDC-I and wolfSSL already have several joint customers that are using the wolfSSL technology in conjunction with DDC-I’s Deos Safety-Critical RTOS, Rose said.
