Beyond Explicit Generators: Distribution-Free Linear-Decomposition Attacks on Public-Key Encryption
Ziyan Chen, Ding-Xuan Zhou
Linear-decomposition attacks can break public-key schemes without recovering the secret algebraic action: when a target public state lies in a known linear span, its decomposition…

Tensor--Action Ko--Lee Cryptography: A Framework and Structural Cryptanalysis of Commuting Subgroup Constructions
Ziyan Chen, Yuqiao Wang
Tensor isomorphism has been studied as an algebraic problem relevant to post-quantum cryptography, while its use in public-key encryption remains open. In this paper, we formulate…
