Embodiment Construction

[0012] In the following detailed description, reference is made to the accompanying drawings which form a part hereof, and in which is shown specific illustrative embodiments by way of illustration. However, it is to be understood that other embodiments may be utilized and logical, mechanical, and electrical changes may be made. Furthermore, the methods presented in the drawing figures and specification are not to be construed as limiting the order in which the various steps may be performed. Therefore, the following detailed description is not to be read in a limiting sense.

[0013] Systems and methods for secure communications over broadband data links are provided. In some implementations, the system includes a packet filtering firewall that filters on source and destination IP addresses and TCP / UDP ports. Additionally, filtering firewalls can be incorporated into the same software partition as the network stack. In another implementation, the digital signature applied ...

Abstract

The invention relates to systems and methods for secure communications over broadband datalinks. Systems and methods for secure communications over broadband datalinks are provided. In certain implementations, a system for providing secure communications through a communication link includes a first communication unit that includes a processing unit that is configured to execute code that causes the first communication unit to verify messages with a firewall as they are received by the first communication unit; remove encapsulation data that encapsulates a message received from a second communication unit; check a digital signature appended to the message received from a second communication unit through a non-secure communication link; perform an integrity check on the message; and when the message is verified through the digital signature and the integrity check, process the message; wherein removal of the encapsulation data and implementation of the firewall is in a first partition and performance of the integrity check and verification of the digital signature is in a second partition.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application Serial No. 62 / 329,728, filed April 29, 2016, which is incorporated herein by reference. Background technique [0003] In some implementations, users accustomed to certain communication standards are interested in communicating over broadband IP channels. For example, airline operators are interested in utilizing broadband IP-based data links being installed for passenger communications to support airline / flight operations communications. One illustrative example where an airline operator seeks to use broadband IP is the ACARS message. ACARS messages may be used to send safety and operational messages, and systems involved in sending and receiving ACARS messages operate primarily in the aircraft domain. In addition, ACARS messages traditionally exchanged over the Aeronautical Data Link and routed through the Data Link Service Provider (DSP) are ins...
