项目摘要
Being a critical infrastructure of our society, the security of low Earth orbit (LEO) satellite networks has a high stake. A satellite network may be subject to excessive attacks launched by strongly motivated adversaries, some of whom are state sponsored with potentially unlimited computing and intelligence resources thus seriously challenging existing security measures, quite often under the assumption that attackers are resource constrained. Assuming this updated threat model, this project will explore new counter-measure defense approaches. The novelties of proposed efforts are to take considerations of the intrinsic resources possessed by a LEO satellite system at its network layer, such as rich and dense satellite connectivity and high satellite mobility, to develop a suite of physical-constrained, rather than computation-constrained, security methods that can improve LEO satellite network’s resilience against attacks. The project's broader significance and importance are to directly address the security threats faced by LEO systems in order to protect the social and economic benefits of this critical infrastructure.This project will fundamentally advance the state of art LEO satellite network security research from several aspects. In particular, by exploiting the global spatial distribution of LEO satellites and their dense connectivity and high mobility, this project will propose physical-constrained randomized multi-path-routing-based secret key generation methods that are immune to resource-unconstrained attacks. This project will also study cyberattacks on the availability of the LEO networks by considering stealthy, intermittent, and selective packet dropping attacks. A novel detection method will be developed to accurately identify those stealthy packet droppers under harsh inter-satellite communication environment caused by the high mobility. Evaluation of all proposed methods will be performed on a scale-down snapshot-oriented static testbed, complemented by computer simulations on satellite-orbiting-trace data of real LEO systems such as Starlink and OneWeb.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
作为我们社会的一个重要基础设施,低地球轨道卫星网络的安全关系重大。卫星网络可能会受到动机强烈的对手发起的过度攻击,其中一些对手是国家支持的,拥有潜在的无限计算和情报资源,从而严重挑战现有的安全措施,通常假设攻击者受到资源限制。假设这种更新的威胁模型,该项目将探索新的反措施防御方法。所提出的努力的新颖性是考虑LEO卫星系统在其网络层所拥有的固有资源,例如丰富和密集的卫星连接性和高卫星移动性,以开发一套物理约束的安全方法,而不是计算约束的安全方法,可以提高LEO卫星网络对攻击的弹性。该项目更广泛的意义和重要性在于直接解决低轨卫星系统面临的安全威胁,以保护这一关键基础设施的社会和经济效益,该项目将从多个方面从根本上推进低轨卫星网络安全研究的最新水平。特别是,通过利用LEO卫星的全球空间分布及其密集的连接性和高移动性,该项目将提出基于物理约束的随机多路径路由的密钥生成方法,该方法不受资源无约束攻击的影响。该项目还将通过考虑隐形、间歇性和选择性丢包攻击来研究对LEO网络可用性的网络攻击。为了在恶劣的星间通信环境下准确识别出高移动性的隐身丢包节点,提出了一种新的检测方法。对所有拟议方法的评估将在一个面向快照的静态试验台上进行,并辅之以对Starlink和OneWeb等真实的LEO系统的卫星轨道跟踪数据的计算机模拟。该奖项反映了NSF的法定使命,并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
