Introduction • Federal Information Security Management Act (FISMA) requires each federal agency to implement a security program to provide information security for the information and information systems • In order to comply with Federal Law and policies of the Chief Information Officer (CIO), the FAA has conducted a threat assessment of Air-Ground communications and has specified a requirement for Air-Ground Security in Segment 1 of the Data Communications program • The capability will be a planned product improvement of the final release of the Segment 1 Ground Automation System (ERAM SW upgrade which will support Enroute clearance deliveries).
Security Approach • Air-Ground Security for Data Communications will be based on the ATN Security Solution specified in ICAO Doc 9880. • The solution provides two-way message authentication of the ground system and aircraft. A draft information paper for the Doc 9880 was presented at the 14th meeting of ACP Working Group M, held in Belgium in June 2009 • The WG-M Paper follows the same security approach which was defined in Doc 9705 Edition 3 with a minor modification to update the domain parameters used in the cryptographic primitives. • Technical documentation to support the two-way authentication approach will be presented for incorporation into DOC 9880, at ICAO ACP WG-M meeting in Paris May 17, 2010.
Related Work • The Air Transport Association (ATA) Digital Security Working Group (DSWG) has developed Specification 42 which contains a Certificate Profile for ACARS Message Security. • Since the updated domain parameters in the draft Doc 9880 have been updated to match ACARS Message Security, the industry standard Specification 42 may be used for the certificate profile. • An Amendment Proposal to update the draft Doc 9880 so that it references Specification 42 will be presented at the upcoming 16th Meeting of ACP Working Group M. • The Data Comm Program is working avionics vendors to determine the most cost effective and technical approach to meet the requirement of providing a two-way authentication to satisfy the threat assessment, and to validate the recommended requirements.
SC 214/ WG 78 References to Security • In order to invoke the security provisions, it is recommended that references to this air-ground security provisions be added to the SC 214/ WG 78 documentation. • The FAA does not plan to make this air-ground security requirement part of the FANS-1/A; the security requirement will be for SC-214 ATN Avionics only.
Action by the Meeting • The meeting is invited to consider the two-way authentication security option for SC-214 ATN Avionics. • The FAA Data Comm Program has made a decision to pursue and validate the two-way authentication option, for implementation as a Segment 1 planned product improvement. • Technical documentation to support the two-way authentication approach will be presented for incorporation into DOC 9880, at ICAO ACP WG-M meeting in Paris May 17, 2010.
