一种抗物理攻击防篡改检测技术

A Temper-Resistant Detecting Technique Against Physical Attack

  • 摘要: 提出一种应用于高安全芯片的抗侵入式物理攻击防篡改检测技术, 利用芯片顶层金属对侵入式攻击进行主动实时监测, 可有效地防止侵入式攻击对电路存储关键信息的提取.提出了针对大规模电路的随机哈密顿回路版图优化加速生成算法, 能够在较短时间内生成高无序、大格点量的拓扑结构.本方法可增加攻击者实施侵入式攻击所需的时间与成本, 提升大尺寸高安全芯片的物理防护能力.

     

    Abstract: A temper resistant detecting technique applied in high security chips is proposed in this paper.The method utilize the topmost layer to monitor attack behaviors in real time, which prevents the key information stored in circuits from being stolen.An optimized algorithm for generating a random hamilton path of the layout in VLSI circuits is proposed.Using this algorithm, a highly disordered topology with a large area can be generated in a short time.The proposed method can increase the time and cost for the invasive attacks and improve the physical defense ability.
