Abstract: In one embodiment, a sender node in a serial network identifies a message identifier for a packet to be sent by the sender node. The sender node selects a cyclical redundancy check (CRC) initialization vector associated with the message identifier. The sender node generates a CRC value for the packet, based on the selected initialization vector. The sender node sends the packet via the serial network. The sent packet includes the message identifier and the generated CRC value. In turn, a receiver node that receives the packet uses the generated CRC value to authenticate the sender node.

Abstract: The secure chain of trust steps to boot-up a computing device are split between the shutdown procedure of the computing device and the boot-up procedure of the computing device to reduce the time required for the computing device to boot-up. The main image associated with a central processing unit of the computing device is validated during the shutdown procedure of the computing device such that the operating system for the central processing unit is available when the computing device receives an action to power on. The boot-up time for the computing device is reduced, which allows the computing device to boot-up within an established time frame.

Abstract: In one embodiment, methods, systems, and apparatus are described in which data to be used by a processor is stored in a memory. Network communications with a data center are enabled via a network interface. The processor maintains a reporting policy for reporting anomalous events to the data center, the reporting policy having at least one rule for determining a reporting action to be taken by the processor in response to an anomalous event. The processor further monitors the IoT device for a report of an occurrence of the anomalous event. The processor performs the reporting action according to the at least one rule, in response to the report of the occurrence of the anomalous event. An episodic update to the reporting policy from the data center may be received at the processor, which modifies the reporting policy in accordance with the update. Related methods, systems, and apparatus are also described.

Abstract: In one embodiment, a technique for performing component self-tests for an in-vehicle network of a vehicle is provided that illustratively comprises: retrieving, by a device in communication with an in-vehicle network (IVN) of a vehicle, a memory sector address of a memory of a component connected to the IVN when a first startup of the vehicle begins, the memory sector address stored in non-volatile memory; performing, by the device, a memory test on a first part of the memory starting at the memory sector address for a predetermined increment during the first startup of the vehicle; and replacing, by the device, the memory sector address with an incremented memory sector address in the non-volatile memory, the incremented memory sector address indicative of the memory sector address incremented by the predetermined increment.
