Abstract: Service disruption prevention through chokepoint identification and monitoring is disclosed. The present disclosure seeks to prevent (or drastically reduce the probability) mass vehicle recovery events due to fragile portions of the map. Choke points are identified by iterating through the lane segments of a map and analyzing the effect of their removal on the service area. Once identified, tooling is used to actively monitor chokepoints using a hybrid polygon with high granularity. Down and upstream effects also can be determined. Based on the monitoring of lane segments and/or areas, location connectivity can be estimated and a map fragility calculated therefrom. If map fragility reaches a critical state, one or more areas can be cut off from the service area.

Abstract: A system includes at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one processor is configured to receive a plurality of doubly-encrypted secret parts that were encrypted using at least a public key belonging to a public/private keypair. The at least one processor is also configured to decrypt each of the plurality of doubly-encrypted secret parts into a corresponding singly-encrypted secret part using a private key belonging to the public/private keypair. The at least one processor is also configured to decrypt each corresponding singly-encrypted secret part into a corresponding secret part. A secret is reconstructed from a quantity of corresponding secret parts that is a subset of a total number of secret parts. The public key, the private key, or both are rotated by creating a new version of the public key, the private key, or both.

The secondary fragment is one of a plurality of secondary fragments of the encryption key. The user is authenticated (e.g., by validating a username/password). The encryption key is regenerated using the secondary fragment and a primary fragment of the encryption key. In response to regenerating the encryption key using the secondary fragment and the primary fragment, and authenticating the user: access is granted, to the user, by unencrypting an encrypted data record using the regenerated encryption key.

Abstract: Methods and systems are described herein for bypassing secondary tiers of authentication for particular security categories. An authentication system, when authenticating a user, may receive an authentication request with authentication data enabling authentication through a multi-tier authentication mechanism. When the request has been authenticated through a multi-tier authentication mechanism, the authentication system may identify a category associated with the request and generate a temporal unlock flag for that category of future requests, such that the temporal unlock flag indicates that multi-tier authentication is not required for a predetermined amount of time for requests of that category. The temporal unlock flag may be inserted into the user's record. When future requests of that same category are received, only a single-tier authentication mechanism may be required for authentication.

Abstract: Upon detecting a lane-change trigger to move an ego vehicle from a current lane to a target lane, a target vehicle is identified in the target lane. Then a set of candidate trajectories is built for the lane-change maneuver by, for each of the target vehicles in the target lane: determining a set of constraints for a lane-change maneuver based on current data collected in the ego vehicle, including speed and distance constraints for the ego vehicle, and adding to the set of candidate trajectories, from a stored set of trajectories, a candidate trajectory for the lane-change maneuver that satisfies the constraints for the lane-change maneuver. Upon determining that the set of candidate trajectories has been built for each of the target vehicles, an optimal trajectory is selected from the set of candidate trajectories. A longitudinal acceleration of the ego vehicle is commanded based on the optimal trajectory.
