Description
It is a curious fact that most efficient algorithms for solving algebraic equations over finite fields are probabilistic. In this talk, I will give an overview over deterministic techniques that are applicable. The case of constructing rational points on elliptic curves is especially relevant for cryptographic applications. I will give a detailed exposition of my algorithm for this purpose and also discuss the complexity from various viewpoints.

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[…]-
