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.

An auto-ICAS compliant system and method of avoiding collisions between aircraft linked by a Link 16 network comprises establishing an ICAS datalink between aircraft less than 10 nautical miles apart. Datalink messages generated and processed by ICAS datalink modules are transmitted and received by Link 16 receivers rather than dedicated ICAS transceivers. The datalink messages are embedded within the propagation delay portions of Link 16 timeslots and exchanged among up to 10 nearby aircraft at a data rate of up to 20 Hz each. Because each Link 16 timeslot can contain a Link 16 message and two 768-bit ICAS datalink messages, conventional Link 16 communication is not impeded. Datalink messages can be software encrypted. Link 16 messages can be encoded using an enhanced throughput Link 16 protocol that includes fewer preamble pulses and/or eliminates STN information. Embedded datalink messages can be transmitted at 1 Watt by a MIDS-JTRS CMN4.

The present subject matter provides various technical solutions to technical problems facing UAV detection and mitigation. Information received from UAV detection sensors may be analyzed or matched against known UAV characteristics. The analysis or matching may be used to identify the UAV, analyze the UAV characteristics or navigational behavior, and classify the UAV behavior and the UAV itself. The UAV may be classified as either compliant, ignorant (e.g., unintentional) and noncompliant, or purposeful (e.g., intentional) and noncompliant. The UAV classification may be improved by using UAV characteristic analysis performed by an artificial neural network (ANN) algorithm using specific UAV classifiers. A UAV mitigation command or mitigation response may be generated based on the UAV characteristic analysis combined with a UAV safety risk assessment. The mitigation command may cause nondestructive interference, destruction, capture, or another UAV mitigation response.
