Abstract
In accordance with some embodiments, in response to the detection of a particular event, an event data recorder may enter a secure mode. In the secure mode, data from various peripherals is collected over a secure channel and stored in a secure memory within the event data recorder. That data may subsequently be read out under secure conditions with an assurance of reliability while the system is in a secure mode, it may continue to collect data in a non-secure mode in parallel.
