- Abstract
- We complete the state-of-the-art on the side-channel security of real-world devices by analysing two 32-bit microcontrollers equiped with an unprotected co-processor. Our results show that (i) the lack of understanding of their hardware architecture can be circumvented with standard detection tools { for this purpose, we combine a simple variation of the Test Vector Leakage Assessment methodology with Signal-to-Noise Ratio estimations, which enables the efficient identification of attack vectors; (ii) standard distinguishers then lead to powerful key recoveries with less than 5,000 traces; and (iii) preprocessing like the continuous wavelet transform can be useful in such a black box evaluation context.
