QNX Black Channel Communications Most embedded systems are connected and have many nodes of communication which can put the safety of the system at risk. To make data communication functionally safe, and reduce the scope and complexity of certifying these systems, BlackBerry® QNX® has developed a pre-certified data communications solution that leverages a Black Channel approach.
QNX Black Channel Communications Technology, certified to ISO 26262 ASIL D, encapsulates the data being exchanged and performs essential safety checks to validate it at both ends. This solution protects data communication from systematic software faults, random hardware faults and transient faults and helps in the automatic prevention of damages from these failures, all with minimal impact on system performance. When paired with a safety-certified RTOS, like the QNX® OS for Safety, certification scope and cost can be greatly reduced.
