Key recovery against 3DES in CPU smart card based on improved correlation power analysis

Yanting Ren, Liji Wu, Hexin Li, Xiangyu Li, Xiangmin Zhang, An Wang, Hongyi Chen
2016 Tsinghua Science and Technology  
In this paper, we integrate appropriate preprocessing methods with an improved attack strategy to generate a key recovery solution to the shortcomings of these countermeasures.  ...  Our proposed attack strategy improves the attack result by combining information leaked from two adjacent clock cycles.  ...  Preprocessing: alignment An unstable clock, a random delay, or inaccurate triggering in measurement [2] usually causes misalignment of the power traces.  ...

Synchronous sampling and clock recovery of internal oscillators for side channel analysis and fault injection

Colin O'Flynn, Zhizhang Chen
2014 Journal of Cryptographic Engineering  
By synchronizing the sampling clock to the clock of the target device, the sample rate requirements are considerably relaxed; the attack will succeed with a much lower sample rate.  ...  This attack is characterized under four conditions: with a stable crystal-oscillator based clock, with a clock that is randomly varied between 3.9 MHz-13 MHz, with an internal oscillator that is randomly  ...  In this form an 'offset' parameter m is added, which slides the comparison window across all points in the recorded trace.  ...

Encoding Power Traces as Images for Efficient Side-Channel Analysis [article]

Benjamin Hettwer
2020 arXiv   pre-print
This is a crucial improvement, as the amount of traces that can be recorded by an attacker is often very limited in real-life applications.  ...  By allowing the neural network to interpret the trace as an image, we are able to significantly reduce the number of required attack traces for a correct key guess.We also demonstrate that the attack efficiency  ...  Such misalignments can occur due to an unstable measurement setup or a jitter-based countermeasure (e.g. by creating an unstable clock signal [32] ).  ...

To verify the proposed attacks, experiments were performed on a trace set collected from an Atmega8515 smart card when it performs AES-128 encryption, a DPA contest v4 dataset and the ASCAD public dataset  ...  In this paper, we propose an efficient profiled attack for on unprotected and masking-protected cryptographic devices based on two CNN architectures, called CNNn, CNNd respectively.  ...  CNN architecture for protected devices Attacks against the masking-protected devices are known as higher-order side channel attacks, where an attacker needs to combine independent leakage information by  ...

PUFs can augment the security architecture of an ever-increasing number of electronic devices that access our personal data and/or represent our identities.  ...  A PUF circuit is designed to be sensitive to process variations, i.e., challenged with a binary input, it provides a binary, device-unique response.  ...  However, neither the procedures SSGen and SSRep nor the transfer of helper data are an explicit part of the proposed protocol.  ...
