摘要：
本文介绍了一种在商用电阻式 RAM（ReRAM）芯片中隐藏数据的新型低成本技术。通过开关（$\textit{set/reset}$）操作操纵其模拟物理特性，数据被隐藏在 ReRAM 单元中。随后，通过感测单元物理特性的变化（即存储单元的 $\textit{set/reset}$ 时间）来检索这些隐藏数据。所提出的系统级隐藏技术不影响正常存储操作，且不需要任何硬件修改。此外，该隐藏方法对温度变化和设备在正常读写操作下的老化具有鲁棒性。硅片结果表明，我们提出的数据隐藏技术速度可接受，编码速率约为 ${\sim}0.4bit/min$，检索速率约为 ${\sim}15.625bits/s$，且在不知道用于增强隐藏信息安全性的密钥的情况下，隐藏信息无法恢复。
英文摘要：
This article introduces a novel, low-cost technique for hiding data in commercially available resistive-RAM (ReRAM) chips. The data is kept hidden in ReRAM cells by manipulating its analog physical properties through switching ($\textit{set/reset}$) operations. This hidden data, later, is retrieved by sensing the changes in cells' physical properties (i.e., $\textit{set/reset}$ time of the memory cells). The proposed system-level hiding technique does not affect the normal memory operations and does not require any hardware modifications. Furthermore, the proposed hiding approach is robust against temperature variations and the aging of the devices through normal read/write operation. The silicon results show that our proposed data hiding technique is acceptably fast with ${\sim}0.4bit/min$ of encoding and ${\sim}15.625bits/s$ of retrieval rates, and the hidden message is unrecoverable without the knowledge of the secret key, which is used to enhance the security of hidden information.
