A first electronic processor is communicatively coupled to a memory and configured to operate one or more vehicle systems. A second electronic processor is configured to generate message authentication codes to verify data communications between the first electronic processor and at least one other vehicle system controller in the controller area network. The direct memory access (DMA) module is configured to facilitate direct communications between the second electronic processor and the memory so that the first electronic processor can continue to execute other instructions while message authentication codes are generated by the second electronic processor for incoming and outgoing message data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reducing runtime load for vehicle system data encryption using crypto engine with direct memory access (DMA)","description":"Systems and methods are presented for secured communications in a controller area network for a vehicle system.
