军用航空电子平台对MIL-STD-1553通信总线攻击的防护
Protecting Military Avionics Platforms from Attacks on MIL-STD-1553 Communication Bus
摘要：
MIL-STD-1553是一个军用标准，它定义了物理层和逻辑层，以及通信总线的命令/响应时间划分多路复用，用于军事和航空航天航空电子平台已有40多年。MIL-STD-1553作为一种传统的平台，其设计目标是高水平的容错，而对安全性的关注较少。最近的研究已经解决了成功的网络攻击对执行MIL-STD-1553的航空航天器的影响。在这项研究中，我们提出了MIL-STD-1553的安全性分析。此外，我们提出了一种方法，在MIL-STD-1553通信总线和它的性能存在的几种攻击情况下，在一个测试平台上实现的异常检测，以及对真实系统数据的结果。此外，我们提出了一个入侵检测系统（IDS）的MIL-STD-1553通信总线的一般方法。
英文摘要：
MIL-STD-1553 is a military standard that defines the physical and logical layers, and a command/response time division multiplexing of a communication bus used in military and aerospace avionic platforms for more than 40 years. As a legacy platform, MIL-STD-1553 was designed for high level of fault tolerance while less attention was taken with regard to security. Recent studies already addressed the impact of successful cyber attacks on aerospace vehicles that are implementing MIL-STD-1553. In this study we present a security analysis of MIL-STD-1553. In addition, we present a method for anomaly detection in MIL-STD-1553 communication bus and its performance in the presence of several attack scenarios implemented in a testbed, as well as results on real system data. Moreover, we propose a general approach towards an intrusion detection system (IDS) for a MIL-STD-1553 communication bus.
