Linearly Homomorphic Ring Signature Scheme over Lattices
Heng Guo, Jia Li, Yanan Wang +3
Construct the first provably secure linear homomorphic ring signature scheme. Ring signatures allow a signer to anonymously sign a message on behalf of a user group (ring) and are…
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…
Linearly Homomorphic Signature with Tight Security on Lattice
Heng Guo, Fengxia Liu, Kun Tian +1
Constructing cryptographic schemes with tight or almost-tight security has long been one of the central problems in theoretical cryptography. At ASIACRYPT 2016, Boyen and Li posed…
On the MacWilliams Theorem over Codes and Lattices
Zhiyong Zheng, Fengxia Liu, Kun Tian
Analogies between codes and lattices have been extensively studied for the last decades, in this dictionary, the MacWilliams identity is the finite analog of the Jacobi-Poisson for…
Towards Quantum-Safe Federated Learning via Homomorphic Encryption: Learning with Gradients
Guangfeng Yan, Shanxiang Lyu, Hanxu Hou +2
This paper introduces a privacy-preserving distributed learning framework via private-key homomorphic encryption. Thanks to the randomness of the quantization of gradients, our lea…
FedReverse: Multiparty Reversible Deep Neural Network Watermarking
Junlong Mao, Huiyi Tang, Yi Zhang +3
The proliferation of Deep Neural Networks (DNN) in commercial applications is expanding rapidly. Simultaneously, the increasing complexity and cost of training DNN models have inte…
Public key cryptosystems based on Iterated Functions Systems
Jacques Peyriere, Fengxia Liu, Zhiyong Zheng +1
Let be a collection of one-to-one functions from some space~ into itself such that the sets are disjoint. If is a word…
