Security verification of 1553B bus components used in aerospace

Abstract

1553B bus is a network interface that manages the bottom communication and control of the hardware system. It is widely used in the aerospace field because of its high reliability, high noise tolerance and flexible connection between devices. However, the basic security protection mechanism wasn’t considered in this bus design. A security verification platform to verify the existence of the security vulnerability was design in this paper, based on which some typical 1553B bus components are verified. The results show that the key node vulnerabilities of 1553B bus system can be exploited, which will affect data transmission and lead to system security failure.
