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 using a removable data storage device having an embedded cryptographic ignition key (CIK) are provided. In one embodiment, a CIK device is embedded into a removable data cartridge used to transfer information for cryptographic processing to a host system. When the removable data cartridge is interfaced with the host system, the CIK device communicates a CIK used to authenticate a user so that the data subject to cryptographic processing can be transferred to and/or otherwise processed by the host system. Once user authentication has occurred, the removable data cartridge can transfer data to the host system for cryptographic processing.

Abstract: Systems and methods using a cryptographic key loader embedded in a removable data storage device are provided. In one embodiment, the removable data storage device can include a dedicated key memory storing one or more cryptographic keys for cryptographic processing of data by a host system. The removable data storage device can further include a dedicated data memory storing data subject to cryptographic processing by the host system. When the removable data cartridge is interfaced with the host system, the cryptographic key(s) and the data subject to cryptographic processing can become accessible to host system.

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 return path system includes inserting RF packets between regular upstream data packets, where the data packets are generated by communication devices such as a computer or interne telephone. The RF packets can be derived from analog RF signals that are produced by legacy video service terminals. In this way, the present invention can provide an RF return path for legacy terminals that shares a return path for regular data packets in an optical network architecture.

Abstract: A return path system includes inserting RF packets between regular upstream data packets, where the data packets are generated by communication devices such as a computer or internet telephone. The RF packets can be derived from analog RF signals that are produced by legacy video service terminals. At a data service hub, a digitized-RF-to-packet converter (DRPC) can convert the RF packets into standard sized packets such as Ethernet packets for processing by a video services controller. In this way, the present invention can provide an RF return path for legacy terminals that shares a return path for regular data packets in an optical network architecture.

The RF packets can be derived from analog RF signals that are produced by legacy video service terminals. In this way, the present invention can provide an RF return path for legacy terminals that shares a return path for regular data packets in an optical network architecture. The invention operates independently of a legacy upstream transmission timing scheme so that the legacy upstream transmission timing scheme can remain effective in preventing data collisions. In other embodiments, the present invention allows for less complex hardware for subscribers that are not taking data services. Further, an optical signal present line in combination with a driver may be employed in order to reduce the amount of hardware in a laser transceiver node.

Abstract: A system and method establishes a secure communication channel over an optical network. More specifically, the system and method can generally include securing a communications channel to prevent unauthorized access such as eavesdropping or masquerading by employing 1) an encryption scheme derived from the non-linear filtering of shift registers, 2) a method for authenticating and exchanging parameters between two parties over an unsecured data channel for deriving a shared encryption key having a property of perfect forward secrecy, and 3) employing a unique format of the messages that can transport non-secret key exchange parameters over an unsecured data channel and secure communications over a data channel.
