摘要

SipHash是基于arx的伪随机函数，针对短输入进行了优化。它是作为一个哈希表查找函数开发的，但它也用于MAC生成。在撰写本文时，我们还没有发现对SipHash的侧通道攻击。本工作是关于CPA攻击在SipHash上的应用。以STM32F0为目标，对ChipWhisperer CW308 UFO Board进行攻击。成功攻击大约需要800个电源走线。利用异或泄露信息攻击密钥。本工作的主要贡献是包含进位传播的二进制加法的幂模型。

Correlation Power Analysis of SipHash

SipHash is ARX-based pseudorandom function optimized for short inputs. It was developed as a hash table lookup function, but it is also used for MAC generation. At the time of writing, there was no side-channel attack on SipHash known to us. This work is about application of CPA attack on SipHash. Attack was performed on ChipWhisperer CW308 UFO Board with STM32F0 target. Approximately 800 power traces were needed for succesful attack. Leakage information from XOR was used to attack cipher key. The main contribution of this work is power model of binary addition including carry propagation.
