WAEA SFW Connectivity Update – Universal Sheraton - March 25, 2010
Introduction
Airworthiness authorities (EASA/FAA) have expressed their concerns regarding
security of new e-enabled aircraft (A380, B787, A350) through SC (Special
Conditions) and CRI (Certification Review Items).
These concerns are now being extended to legacy aircraft that have been
modified to include such e-enabled systems. On January 15th 2010 the FAA
published an SC applicable to the B747-8/8F, due to the introduction of new
technologies on this modified ‘legacy’ aircraft.
The main novelty is the use of digital system architecture composed of several
connected networks / domains:
•Flight safety related control, communication and navigation systems (ACD –
Aircraft Control Domain)
•Airline business and administrative support (AISD – Airline Information System
Domain)
•Passenger information and entertainment (PIESD – Passenger Information and
Entertainment System Domain)
and the concern that these networks may be subject to unauthorized access.

As a consequence, “Connectivity” has to be taken in a scope wider than only
Cabin Connectivity, including all kinds of communication (ground system to
aircraft systems and aircraft systems to aircraft systems).
Similar special conditions were issued early in 2008 for the B787 (‘Isolation or
Protection from Unauthorized Passenger Domain Systems Access’ and
‘Protection of Airplane Systems and Data Networks from Unauthorized External
Access’).
Airbus has demonstrated compliance with Certification Review Items (CRI) on:
•A330 / A340: CRI S1068 “Aircraft Information Network System (AINS)” and CRI
S1072 “Cabin Information Network System (CINS) and Wireless Area Network”
(Note: CRI S1068 and CRI S1072 do not mention any requirements or security
principles for IFE systems or interfaces)
“This safety assessment process should take into account possible human
intentional aggressions through the open world using airborne peripherals or
through application at the Airport LAN level. Note: Human intentional aggression
on networks is recognized by JAA as a difficult area.”
WAEA SFW Connectivity Update – Universal Sheraton - March 25, 2010
“Airbus should demonstrate that network is sufficiently protected against this
hazard. Airbus should demonstrate that users application (including user
modifiable software) cannot impact the protection/segregation mechanism
(between the avionics world and the open world).”
•A380: CRI F-21 “Network Server System (NSS)” and CRI F-47 “Cabin
Information Network System (CINS) and Wireless Area Network”
(Note: CRI F-21 and CRI F-47 do not mention any requirements or security
principles for IFE systems or interfaces)
“Airbus should demonstrate that the avionics network is sufficiently protected
against Human intentional aggression on networks and that users’ application
(user modifiable software) cannot impact the protection/segregation
mechanism (between the avionics world and the open world.”
WAEA SFW Connectivity Update – Universal Sheraton - March 25, 2010
“According to this [CINS safety assessment] analysis, Airbus should define
the design assurance levels and software levels of each CINS component or
function. This safety assessment process should address possible human
intentional aggressions through CINS applications and use of passengers
PEDs.”
“Passenger’s wired or wireless access to CINS should result in NO increased
security vulnerabilities to the aircraft or its systems. Airbus should conduct
appropriate validation testing of those interfaces to confirm there are no
security vulnerabilities.”
On the A350 we will have to demonstrate compliance with CRI F-38, FAA SA1 and FAA SA-2.

The following needs to be answered with respect to those functions:
Manage off-board communications
•Which air-ground (ground-ground) links shall be supported? If this link is shared
with cockpit communications, have all necessary studies been done to ensure
aircraft performance and security are not affected by such connectivity traffic?
•Are applicable certification rules for new e-enabled aircraft (A350, B787, B7478) which require segregation between cabin and operational communications
met?
Manage on-board wireless signals function:
•Are the proposed wireless frequencies to be used in line with regulatory
standards and Airbus directives?
•Are wireless communications used (or planned to be used) by other
maintenance, cabin or cockpit applications? If yes,
• How to ensure that aircraft performance is not affected?
• How to secure the evolution and coexistence of several wireless systems
on board as well as continuous compliance to regulatory requirements

Manage on-board networks and interfaces
•Does the proposed solution follow regulatory and Airbus security standards
given that we are talking about cabin systems accessed by passengers and
cabin crew?

60 GHz Broadband
Currently, there is a lively discussion about using the 60 GHz band for on- and
off-aircraft applications that require high data rates.
A number of developments have generated this interest:
•FCC has made available 7 GHz of unlicensed bandwidth in the 60 GHz band
providing potential for data rates of several Gigabits/s
•IEEE standard 802.15.3c is being developed for mm-wave communications
•Technological developments such as 60 GHz transceiver circuits with cost
efficient silicon based technologies as well as the progress in memory
technology enable the development of ultra-high data rate communication
system
The EASY-A project (Enablers for Ambient Services & Systems Part A – 60 GHz
Broadband links) has been initiated to cover a comprehensive investigation
concerning the usability of the 60 GHz band as well as the elaboration of efficient
system and implementation concepts.
WAEA SFW Connectivity Update – Universal Sheraton - March 25, 2010
The project covers a range of potential applications including a WLAN system for
video streaming into an aircraft cabin or vehicle as well as the development of a
fast wireless data synchronization link for consumer applications.
The EASY-A consortium consists of 14 institutions – 9 from industry, 3 research
institutes and 2 universities. Additionally a number of subcontractors will supply
specific know-how to the consortium.
Airbus is involved through EADS Innovation Works (an EASY-A consortium
member) and is working on a sub-project “Cabin integration and test of a 60 GHz
system” and the realisation of a high-data rate wireless IFE system in an aircraft
cabin.
EADS Innovation Works / Airbus are working on the following topics:
•Specification of the 60 GHz IFE system
•Characterisation of different cabin materials at 60 GHz
•Definition of areas to install the antennae and integration of the antenna
modules into the ceiling and seats of the cabin
WAEA SFW Connectivity Update – Universal Sheraton - March 25, 2010
• Development of higher-layer protocols and of the application software for the
IFE system
• Development of the HMI interface for the passenger
• Supply of the server
• Integration of the complete 60 GHz IFE system (consisting of one ceiling
module and five seat modules) into an A340 mock-up at EADS IW
