随着社会的不断发展,综合化航空电子系统也得到了飞速的发展,在近几年的发展中逐渐呈现出综合化、模块化和网络化的特点。航空电子系统的综合化指的是能在最大程度上保障信息的共享,能确保飞机的飞行的速度和质量,但与此同时,航空电子系统也面临着网络信息安全的挑战,航空电子系统综合化既要保障信息网络的安全,又能抵制一些恶意信息的入侵,确保能准确及时的应对突发事件的干扰,并对外界的情况能实时的进行防御,本文就要探究综合航空电子系统自身的特点,对其系统保障关键技术进行分析。 With the continuous development of society, the integrated avionics system has also been developed rapidly. In the recent years, it has gradually become integrated, modular and networked. The integration of avionics systems means that information can be shared to the maximum extent and the flight speed and quality of the aircraft can be ensured. However, at the same time avionics systems also face the challenge of network information security. The integration of avionics systems It is necessary to protect the safety of information network, but also to resist the invasion of some malicious information to ensure accurate and timely response to unexpected events, and the real-time defense of the outside world, this article will explore the integrated avionics system itself The characteristics of its system to protect the key technologies for analysis.
