光片上网络增益竞争攻击的建模与研究
Modeling and Exploration of Gain Competition Attacks in Optical Network-on-Chip Architectures
摘要：
片上网络（NoC）能够在片上系统架构中的众多组件之间实现节能通信。光片上网络被广泛认为是克服传统片上电互连带宽和能量限制的关键技术。虽然光学NoC可以提供高性能，但由于光学互连的性质，它们具有固有的安全漏洞。在本文中，我们研究了光NoCs中的增益竞争攻击，它可以由攻击者向光波导注入高功率信号来发起，从而抢夺放大的合法信号。据我们所知，我们提出的方法是第一次尝试调查增益竞争攻击作为一个安全威胁的光学NoCs。我们建模的攻击和分析其对光学NoC性能的影响。我们还提出了潜在的攻击检测技术和对策，以减轻攻击。我们使用不同的NoC拓扑结构和不同的流量模式的实验评估表明，我们的建模和探索的光NoC架构中的增益竞争攻击的有效性。
英文摘要：
Network-on-Chip (NoC) enables energy-efficient communication between numerous components in System-on-Chip architectures. The optical NoC is widely considered a key technology to overcome the bandwidth and energy limitations of traditional electrical on-chip interconnects. While optical NoC can offer high performance, they come with inherent security vulnerabilities due to the nature of optical interconnects. In this paper, we investigate the gain competition attack in optical NoCs, which can be initiated by an attacker injecting a high-power signal to the optical waveguide, robbing the legitimate signals of amplification. To the best of our knowledge, our proposed approach is the first attempt to investigate gain competition attacks as a security threat in optical NoCs. We model the attack and analyze its effects on optical NoC performance. We also propose potential attack detection techniques and countermeasures to mitigate the attack. Our experimental evaluation using different NoC topologies and diverse traffic patterns demonstrates the effectiveness of our modeling and exploration of gain competition attacks in optical NoC architectures.
