Nonexistence of certain classes of generalized bent functions: Revisiting the element partition method

Shi Ying, Yingpu Deng

We obtain new nonexistence results for two classes of generalized bent functions from $Z_{q}^{n}$ to $Z_{q}$ , called type $[n, q]$ generalized bent functions. The…

An Explicit Construction of Orthogonal Basis in $p$ -adic Fields

Chi Zhang, Yingpu Deng

In 2021, the $p$ -adic signature scheme and public-key encryption cryptosystem were introduced. These schemes have good efficiency but are shown to be not secure. The attack succeed…

Norm Orthogonal Bases and Invariants of $p$ -adic Lattices

Chi Zhang, Yingpu Deng, Zhaonan Wang

In 2018, the longest vector problem (LVP) and the closest vector problem (CVP) in $p$ -adic lattices were introduced. These problems are closely linked to the orthogonalization proc…
