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: In one embodiment, a method for ransomware-aware file backup is implemented on a computing device and includes: backing up a target population of files from a target file location in a backup transaction, computing a backup delta score for the backup transaction, where the computing comprises comparing backup data from the backup transaction with backup data from a previous backup transaction, determining whether the computer backup delta score exceeds a pre-defined threshold, and upon the computed backup delta score exceeding the pre-defined threshold: determining that the backup transaction is indicative of a ransomware infection, and performing at least one counter-measure in response to the ransomware infection.

Abstract: In one embodiment, a vehicle having a plurality of network interfaces communicates with a first communication network via a first one of the network interfaces. The vehicle receives performance data regarding the first communication network and one or more other communication network, wherein the received performance data is associated with a particular location. The vehicle determines in advance of arriving at the particular location that the vehicle should switch from communicating with the first communication network to communicating with a selected one of the one or more other communication network, based on the received performance data. At the particular location, the vehicle switches from communicating with the first communication network via the first network interface to communicating with the selected communication network via a second one of the plurality of network interfaces.

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.
