使用DFA攻击硬件AES

Attacking Hardware AES with DFA

Yifan Lu

摘要:

我们提出了第一个实际的攻击硬件AES加速器与256位嵌入式密钥使用DFA。我们确定的挑战,适应著名的理论AES DFA模型的攻击下,从电压故障注入硬件和目前的解决方案,这些挑战。结果,我们成功地在几个小时内以最小的成本从安全计算系统中恢复了278个真实的AES-256密钥。

英文摘要:

We present the first practical attack on a hardware AES accelerator with 256 bit embedded keys using DFA. We identify the challenges of adapting well-known theoretical AES DFA models to hardware under attack from voltage fault injection and present solutions to those challenges. As a result, we managed to recover 278 real-world AES-256 keys from a secure computing system in a matter of hours with minimal cost.
