Abstract: Some methods may involve receiving, at a first node of the health network, encrypted sensor data from one or more sensors. The first node may be in a data communication path between the one or more sensors and other nodes of the health network. The method may involve decrypting, by the first node of the health network, only a portion of the encrypted sensor data, and transmitting the encrypted sensor data from the first node of the health network to a second node of the health network. The first node may be a gateway device. In some examples, the second node may be able to decrypt more of the encrypted sensor data than the first node.

Abstract: A system for preventing cyber security attacks over the CAN bus of a vehicle, from carrying out their plot. The system includes a teleprocessing device that is provided with the message identifier of at least one ECU to be blocked. The teleprocessing device is configured to read the message identifier of CAN messages, to thereby identify the at least one ECU to be blocked. Upon determining that the vehicle is under a cyber security attack, the ECU blocking device is activated. Upon identifying that a message was transmitted by the at least one ECU to be blocked, then during the CAN bus ‘bit monitoring’ process, before the at least one ECU to be blocked reads back the transmitted signal, the ECU blocking device alters one or more bits of the transmitted signal, to thereby force the message to be an erroneous CAN message.

Abstract: A network processor provides for in-line encryption and decryption of received and transmitted packets. For packet transmittal, a processor core generates packet data for encryption and forwards an encryption instruction to a cryptographic unit. The cryptographic unit generates an encrypted packet, and enqueues a send descriptor to a network interface controller, which, in turn, constructs and transmits an outgoing packet. For received encrypted packets, the network interface controller communicates with the cryptographic unit to decrypt the packet prior to enqueuing work to the processor core, thereby providing the processor core with a decrypted packet.
