Description
A novel side-channel-based reverse engineering technique is introduced, capable of reconstructing a procedure solely from inputs, outputs, and traces of execution. Beyond generic restrictions, no prior knowledge of the procedure or the chip it operates on is assumed. These restrictions confine the analysis to 8-bit RISC constant-time software implementations. Specifically, the feasibility of reconstructing a symmetric cryptographic cipher is demonstrated, even in scenarios where traces are sampled with information loss and noise, such as when measuring the power consumption of the chip.

Module Learning With Errors and Structured Extrapolated Dihedral Cosets
Speaker : Jinwei Zheng - Télécom Paris
The Module Learning With Errors (MLWE) problem is the fundamental hardness assumption underlying the key encapsulation and signature schemes ML-KEM and ML-DSA, which have been selected by NIST for post-quantum cryptography standardization. Understanding its quantum hardness is crucial for assessing the security of these standardized schemes. Inspired by the equivalence between LWE and[…]-
