ABSTRACT
MIL-STD-1553 is a military standard that defines the interface and protocol for data buses used in military aircraft and other aerospace applications. It is a reliable and robust communication protocol that ensures the efficient transfer of data on the bus. However, the increasing use of MIL-STD-1553 in critical systems has led to a growing concern about the security of these systems. Intrusion detection is an important aspect of securing these systems and preventing unauthorized access.
This report presents an approach to detect intrusions on MIL-STD-1553 bus systems by tracking changes with respect to known timing properties of the bus using the ECP e-divisive algorithm. The ECP e-divisive algorithm is a statistical method that is based on the concept of change point detection.
The proposed detection model was evaluated using a dataset collected through a MIL-STD-1553 simulator. The outcome of the evaluation showed that the ECP e-divisive algorithm was effective in detecting intrusions on MIL-STD-1553 bus systems. It can detect a wide range of attack vectors and is also able to adapt to changing conditions on the bus, such as changes in the number of Remote Terminals or the amount of data being transferred.
