Authenticated Private Set Intersection: A Merkle Tree-Based Approach for Enhancing Data Integrity
Zixian Gong, Zhiyong Zheng, Zhe Hu +4
Private Set Intersection (PSI) enables secure computation of set intersections while preserving participant privacy, standard PSI existing protocols remain vulnerable to data integ…
MacWilliams Theory over Zk and nu-functions over Lattices
Zhiyong Zheng, Fengxia Liu, Kun Tian
Continuing previous works on MacWilliams theory over codes and lattices, a generalization of the MacWilliams theory over for codes is established, and the comple…
Codes over Finite Ring , MacWilliams Identity and Theta Function
Zhiyong Zheng, Fengxia Liu, Kun Tian
In this paper, we study linear codes over based on lattices and theta functions. We obtain the complete weight enumerators MacWilliams identity and the symmetrized w…
Authenticated Sublinear Quantum Private Information Retrieval
Fengxia Liu, Zhiyong Zheng, Kun Tian +5
This paper introduces a novel lower bound on communication complexity using quantum relative entropy and mutual information, refining previous classical entropy-based results. By l…
Semigroup-homomorphic Signature
Heng Guo, Kun Tian, Fengxia Liu +1
In 2002, Johnson et al. posed an open problem at the Cryptographers' Track of the RSA Conference: how to construct a secure homomorphic signature on a semigroup, rather than on a g…
