Intellectual property (IP) reuse is a well-known technique in chip design industry. But this technique also exposes a security vulnerability called IP stealing attack. Network-on-Chip (NoC) is an on-chip scalable communication medium and is used as an IP and sold by various vendors to be integrated in a Multiprocessor System-on-Chip (MPSoC). An attacker can launch IP stealing attack against NoC IP. In this article, we propose a NoC IP protection technique called circular path--based fingerprinting (CPF) using fingerprint embedding. We also provide a theoretical model using polyomino theory to get the number of distinct fingerprints in a NoC. We show that our proposed technique requires much less hardware overhead compared to an existing NoC IP security solution and also provides better security against removal and masking attacks. In particular, our proposed CPF technique requires 27.41% less router area compared to the existing solution. We also show that our CPF solution does not affect the normal packet latency and hence does not degrade the NoC performance.

基于循环路径指纹的片上网络知识产权保护

知识产权(IP)重用是芯片设计行业的一项众所周知的技术。但这种技术也暴露了一个安全漏洞,称为 IP 窃取攻击。片上网络 (NoC) 是一种片上可扩展通信介质,用作 IP 并由各个供应商出售,以集成到多处理器片上系统 (MPSoC) 中。攻击者可以对 NoC IP 发起 IP 窃取攻击。在本文中,我们提出了一种使用指纹嵌入的 NoC IP 保护技术,称为基于循环路径的指纹识别 (CPF)。我们还提供了一个理论模型,使用 polyomino 理论来获得 NoC 中不同指纹的数量。我们表明,与现有的 NoC IP 安全解决方案相比,我们提出的技术需要的硬件开销要少得多,并且还可以提供更好的安全性来防止删除和屏蔽攻击。特别是,与现有解决方案相比,我们提出的 CPF 技术需要的路由器面积减少 27.41%。我们还表明,我们的 CPF 解决方案不会影响正常的数据包延迟,因此不会降低 NoC 性能。
