Abstract:

A vessel includes a body, such as surfboard, that floats in water. One or more thrusters, and one or more sensors are provided on the body. A controller is configured to selectively activate the thrusters to cause the vessel to move along a path through the water, receive sensor data from the one or more sensors while the vessel is moving along the path, determine, based on the sensor data, whether a dangerous condition is present in the water; and output a warning when the dangerous condition is present in the water. For example, the collected sensor data may relate to locations and directions of currents in the water, the dangerous condition may relate to a rip current, and the warning may identify at least one attribute of the rip current. A map identifying a location of the dangerous condition may be generated and forwarded to other devices.

Abstract:

A secure hardware-based module or Security Electronic Control Unit (SECU) for a Controller Area Network (CAN) prevents an attacker from sending malicious messages through the CAN bus to take over control of a vehicle. The SECU shares a unique key and counter with each ECU on the CAN bus. When a legitimate ECU sends a message, it first compresses the message and then generates a MAC of the counter and a secret key. The counter is increased by one for each transmitted message. The ECU then fits the compressed message and the MAC into one CAN frame and sends it onto the CAN bus. The SECU performs the message verification on behalf of the intended receiver(s) of the message. If the verification passes, the receiver(s) simply decompress the message and use it as a normal CAN message. If the verification fails, the SECU will corrupt the CAN frame before it is fully received by the intended receiver(s). The corrupted CAN frame will be ignored by the intended receiver(s) as if it was never received. Therefore, a malicious message generated by an attacker will inflict no damage on the system.
