The three traditional objectives of computer security are confidentiality, integrity and availability.
Availability can be defined as the prevention of denial of service. Confidentiality and integrity have
been addressed in several theoretical works whereas the concept of availability has not been much
investigated by the scientific community. This paper is an attempt to define through a case study the
concept of availability. We first define a set of availability constraints that avionic data bus protocols
should enforce. Then, we consider the ARINC 629 Basic Protocol (BP) and the ARINC Combined
Protocol (CP) which were implemented on the Boeing 777. We check whether these protocols
respect our availability constraints or not.
