最近关于FPGA硬件安全性的研究表明,功率冲击存在巨大的潜在风险,这种风险使用高开关活动来产生过多的动态功率负载。几乎所有目前的功率锤击攻击方案都是基于某种环形振荡器,存在缓解策略。在本文中,我们使用一种不同的策略来创建过度的动态功耗:毛刺放大。通过仔细设计异或树,可以实现快速开关线,在驱动高扇出网络的同时,可以汲取足够的功率来崩溃FPGA。除了攻击(这是崩溃的Ultra96板),我们将提出一个扫描仪检测恶意毛刺放大FPGA设计。
Recent work on FPGA hardware security showed a substantial potential risk through power-hammering, which uses high switching activity in order to create excessive dynamic power loads. Virtually all present power-hammering attack scenarios are based on some kind of ring oscillators for which mitigation strategies exist. In this paper, we use a different strategy to create excessive dynamic power consumption: glitch amplification. By carefully designing XOR trees, fast switching wires can be implemented that, while driving high fan-out nets, can draw enough power to crash an FPGA. In addition to the attack (which is crashing an Ultra96 board), we will present a scanner for detecting malicious glitch amplifying FPGA designs.
