SecOC PDU

class scapy.contrib.automotive.autosar.secoc_canfd.SecOC_CANFD(_pkt, /, *, flags=<Flag 0 ()>, identifier=0, length=None, fd_flags=<Flag 4 (fd_frame)>, reserved=0, pdu_payload=<Raw |>, tfv=0, tmac=None)[source]

Bases: CANFD, SecOCMixin

classmethod dispatch_hook(s: bytes | None = None, *_args: Any, **_kwds: Any) → Packet_metaclass[source]: dispatch_hook determines if PDU is protected by SecOC. If PDU is protected, SecOC_PDU will be returned, otherwise AutoSAR PDU will be returned.

extract_padding(s: bytes) → Tuple[bytes, bytes | None][source]
