A method and tools for virtually aligning object detection sensors on a vehicle without having to physically adjust the sensors. A sensor misalignment condition is detected during normal driving of a host vehicle by comparing different sensor readings to each other. At a vehicle service facility, the host vehicle is placed in an alignment target fixture, and alignment of all object detection sensors is compared to ground truth to determine alignment calibration parameters. Alignment calibration can be further refined by driving the host vehicle in a controlled environment following a leading vehicle. Final alignment calibration parameters are authorized and stored in system memory, and applications which use object detection data henceforth adjust the sensor readings according to the calibration parameters.

A system and method for a vehicle-to-vehicle communications system that provide active safety applications employing lightweight geographic authentication using one-time signatures. The system and method require each vehicle to construct a discretized representation of its trajectory, which captures its kinematical history to a tunable degree of accuracy and to a tunable extent in the past. This trajectory information is then signed using a one-time signature. Thus, with every periodic message, the sending vehicle transmits the usual application payload, a signed version of the trajectory as described, and the digital signature over all of the fields.

The disclosed protocol is secure against any minority of malicious parties (which is optimal). The disclosed method is useful in establishing sensitive distributed cryptographic function sharing services (certification authorities, signature schemes with distributed trust, and key escrow authorities), as well as other applications besides RSA (namely: composite ElGamal, identification schemes, simultaneous bit exchange, etc.). The disclosed method can be combined with proactive function sharing techniques to establish the first efficient, optimal-resilience, robust and proactively-secure RSA-based distributed trust services where the key is never entrusted to a single entity (i.e., distributed trust totally "from scratch"). The disclosed method involves new efficient "robustness assurance techniques" which guarantee "correct computations" by mutually distrusting parties with malicious minority.
