研究開始時の研究の概要 |
In this research, we aim to develop novel cryptanalysis techniques to understand the security of new symmetric-key primitives designed for advanced public-key techniques like secure multiparty computation (MPC), fully homomorphic encryption (FHE), and zero-knowledge proof systems (ZKP). In particular, we are interested in 1) how to access the security of ciphers using partial nonlinear layers, 2) how to understand the security of randomized symmetric-key primitives, and 3) how to develop new algebraic attacks over large finite fields.
