Abstract

The FPGA world recently experienced significant changes with the introduction of new Systems-on-Chip (SoCs) embedding high-end microprocessors and programmable logic on the same integrated circuit. The architecture of these SoCs can be exploited to offer an unprecedented level of monitoring of the memory accesses of running software components, a key element of performance, safety and security analysis. This paper presents the hardware / software implementation of such a memory tracing tool on one of these SoCs. It also proposes example applications in the security field and two attacks --- a pass-phrase retrieval and an access control bypass --- to demonstrate the power of hardware-assisted memory tracing.
嵌入FPGA结构的新型soc的硬件辅助内存跟踪
随着新的片上系统(soc)在同一集成电路上嵌入高端微处理器和可编程逻辑,FPGA世界最近经历了重大变化。这些soc的体系结构可以被利用来提供前所未有的对运行软件组件的内存访问的监控,这是性能、安全性和安全性分析的关键因素。本文介绍了这种内存跟踪工具在其中一个soc上的硬件/软件实现。它还提出了安全领域的示例应用和两种攻击——密码短语检索和访问控制绕过——来展示硬件辅助记忆跟踪的强大功能。
