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 filtering aircraft messages are provided. In one embodiment, the method can include receiving a message including a plurality of data fields containing data associated with the message. The method can include accessing a set of configuration data. The set of configuration data can include a set of data identifying one or more potential message structures and one or more parameters. The parameters can include one or more conditions for processing the data fields. The method can include determining a message structure of the message based at least in part on the data fields and the first set of data identifying one or more potential message structures. The method can include processing the message based at least in part on the message structure and the parameters. The method can include generating a filtered message that is based at least in part on the processed message.

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.

Abstract: A method for rapid restarting of a flight control system, wherein the flight control system comprises a processor, is provided. The method includes storing at least one executable program on a memory device and copying the at least one executable program to a first random access memory (RAM) sector and a second RAM sector of a RAM memory device at a predetermined time. The method also includes copying the at least one executable program from the second RAM sector to the first RAM sector upon a restart of the processor and reinitializing processor operation by executing the at least one executable program copied from the second RAM sector to the first RAM sector.
