Abstract: Computer systems and methods for replicating a portion of a data set to a local repository associated with a subnetwork are disclosed. In one implementation, a method for a device associated with a subnetwork may include obtaining a portion of a data set from a central repository. The data set may be associated with one or more subnetworks, and the portion of the data set may be associated with the subnetwork. The method may further include obtaining a request for data originating from a node in the subnetwork. The requested data may include at least one of (i) the portion of the data set, and (ii) data generated based on the portion of the data set, and the request may be destined for the central repository. In addition, the method may include determining whether the central repository is unavailable to provide the requested data, and providing the requested data to the node after the central repository is determined as being unavailable.

Abstract: Systems and methods are described that enable trusted communications between two entities. In one implementation, a controller of a vehicle may include one or more processors configured to receive data and a controller signature from a second controller of the vehicle. The controller signature may be generated based on at least a first portion of the data. The one or more processors may be further configured to transmit the data and the controller signature to a gateway of the vehicle and receive a gateway signature from the gateway. The gateway signature may be generated based on at least a second portion of the data and transmitted to the controller after the gateway verified the controller signature. In addition, the one or more processors may be configured to verify the gateway signature and process the data.

Abstract: Computer systems and methods for verifying a route taken by a communication are disclosed. In one implementation, a device for verifying a route taken by a communication may include one or more processors configured to obtain a communication transmitted by a source entity. The communication may include data and digital signatures, and each of the digital signatures may be generated based on at least the data. Further, the digital signatures may include a digital signature associated with the source entity, and a set of digital signatures associated with at least a subset of intermediate entities on a route taken by the communication. The one or more processors may be further configured to verify the digital signatures included in the communication, verify whether the entities associated with the digital signatures form an expected route for the communication, and process the data.

Abstract: Systems and methods are described that mitigates and/or prevents distributed denial-of-service (DDOS) attacks. In one implementation, a gateway include one or more processors configured to obtain network data from one or more entities associated with the gateway, provide the network data to a server, and obtain a set of entity identifiers from the server. The set of entity identifiers may be generated based on at least the network data. The one or more processors may be further configured to filter communications based on the set of entity identifiers.
