Abstract

The invention relates to a key management method for an integrated avionic system. The key management functions in the entire process from the generation to final destruction of a key and is realized as a functional component for the safety management (GSM-SM) of system management in an integrated modular avionic (IMC) system to perform unified management on all keys in the system; and the key management mainly comprises the following steps of: 1) generating the keys; 2) loading the keys; 3) distributing the keys; and 4) using the keys. The method is favorable for improving the active defenselevel of airborne embedded systems of China, constructing and perfecting a safety guarantee system of the integrated avionic system, defending an equipment system against foreign threats and improving the destruction resistance of the aviation equipment system.

Description

technical field [0001] The invention relates to the field of integrated avionics systems, in particular to a key management method for an integrated avionics system. Background technique [0002] Aviation information security is one of the most challenging issues of airborne integrated core processing system, which has attracted widespread attention at home and abroad. In a highly integrated avionics system, a large number of computing, communication, and control services are provided by an on-board integrated core processing system on the aircraft, and various data and codes with different security levels are processed and run on the same platform. This approach brings new safety challenges to the avionics system on the aircraft. [0003] The integrated avionics system adopts a hierarchical distributed architecture, and the general system management (GSM) is the core of its management. It also adopts a hierarchical management model and is divided into three levels, namely ...
