Abstract: Systems and methods for managing aircraft messages are provided. In one embodiment, the method can include receiving a message from an onboard system of an aircraft. The method can include determining a priority associated with the message based, at least in part, on data associated with the message. The data can be indicative of at least a content of the message. The method can include determining data indicative of availability for each of a plurality of communications networks based, at least in part, on one or more first parameters associated with the aircraft. The method can include selecting a network based, at least in part, on message priority, the data indicative of availability, and one or more second parameters associated with each of the networks. The method can include sending the message via the selected network when the network is available, or storing the message when the network is unavailable.

Abstract: Systems and methods for configuring a cryptographic system, such as an avionic data transfer system associated with an aircraft, are provided. More particularly, systems and methods can be used to assemble a cryptographic key configuration (CKC) for use in a cryptographic system. A CKC can include various components for configuration of a cryptographic system. An administrator can generate CKCs for multiple host systems via a user interface (e.g., a graphical user interface) at a terminal and can deliver the CKCs to the host systems via an automated process by way of, for instance, a removable data cartridge.

Abstract: Systems and methods for managing cryptographic keys in an avionic data transfer system are provided. A host device associated with the avionic data transfer system can receive one or cryptographic keys via a key fill interface. For instance, in one embodiment, the host device can receive one or more cryptographic keys from a removable data cartridge. The host device can act as a key server for other cryptographic units associated with the avionic data transfer system via a data bus. For instance, the host device can distribute one or more cryptographic keys to other cryptographic units associated with aircraft via an aircraft bus. The other cryptographic units can use the one or more cryptographic keys for cryptographic processing of data.
