Abstract: The present invention generally relates to systems and methods for encrypting data. The disclosed techniques can include tracking a plurality of flight parameter values for a plurality of flight parameters of an aircraft, generating a first cryptographic key from the plurality of flight parameter values, encrypting plaintext using the first cryptographic key to generate a first ciphertext, and sending, from a sender to a receiver, a message comprising the first ciphertext.

Abstract: An aircraft includes an aircraft network having nodes and links and a sandbox network in communication with the aircraft network. The sandbox network simulates the aircraft network and includes sandbox nodes corresponding to the nodes of the aircraft network, a first set of sandbox links corresponding to the links of the aircraft network, and a second set of sandbox links providing communication between sandbox nodes not in communication via the first set of sandbox links. Computer executable instructions, when executed, perform the steps of: generating network traffic over the sandbox network such that the sandbox network models a behavior of the aircraft network; identifying a suspicious activity on the aircraft network; routing the suspicious activity from the aircraft network to the sandbox network; and analyzing the suspicious activity as the suspicious activity traverses through the sandbox network.

Abstract: An aircraft includes an aircraft network having a plurality of nodes that are segregated into a plurality of zones, each zone defining a different level of potential threat to the aircraft network. Each of the plurality of nodes has computer executable instructions that can receive data from another of the plurality of nodes; inspect net flow across the aircraft network based on a source location of the data; and identify a security event based on the received data, the plurality of potential entry points, a plurality of potential attack vectors that include vectors between nodes organized in the same zone and vectors between nodes organized in different zones, and a model of the dataflow of the aircraft network.
