As mentioned in Section 4.1 , we also find data authentication important for the static segment, since a resourceful attacker might attempt to prevent a benign node from sending a null frame in an empty static slot …
WebJan 1, 2024 · The FlexRay bus is a communication standard used in the automotive industry. It offers a deterministic message transmission in the static segment following a time-triggered schedule. WebApr 24, 2024 · The FlexRay dynamic segment is partitioned into a number of minislots (MS) that are of equal length. Each frame is assigned a frame identifier (FrameID, or simply ID) within which it can transmit. The dynamic segment is arbitrated in the following way. At the beginning of the dynamic segment, the minislot index is set to one.
