Signal processing device and vehicle communication device comprising same

A signal processing device comprising:

• a first processor configured to receive a first message including an in-vehicle sensor signal based on a first communication scheme, and to perform signal processing on the received first message;
• and
• a first accelerator configured to accelerate processing of the message received using the first communication scheme,
• wherein:
• the first processor performs first type intrusion detection;
• and
• the first accelerator performs second type intrusion detection different from the first type intrusion detection.

A vehicle communication device comprising a signal processing device,

• wherein the signal processing device comprising:
• a first processor configured to receive a first message including an in-vehicle sensor signal based on a first communication scheme, and to perform signal processing of the received first message;
• a second processor configured to receive a second message including a communication message received from an external source based on a second communication scheme, and to perform signal processing of the received second message;
• and
• a first accelerator configured to accelerate processing of the message received using the first communication scheme,
• wherein the first processor and the first accelerator perform intrusion detection on the first message in a shared manner.
