Improved Dual Attack and Trapdoor Sampling via Quantum Rejection Sampling
Cong Ling, Hao Yan, Nicholas Zhao
In this work, we revisit the dual attack and GPV trapdoor sampling, focusing on the lattice Gaussian sampling term, which can be a significant bottleneck in the overall complexity.…

Construction over Multiquadratic Fields for Compound Block-Fading Wiretap Channels
Juliana G. F. Souza, Conghui Li, Cong Ling
We construct multilevel lattice codes from multiquadratic number fields for the compound block-fading wiretap channel. More precisely, we specialize Construction over the ri…

Multilevel lattice codes from Hurwitz quaternion integers
Juliana G. F. Souza, Sueli I. R. Costa, Cong Ling
This work presents an extension of the Construction lattices proposed in \cite{huang2017construction}, to Hurwitz quaternion integers. This construction is provided by using…
