The Capacity of Collusion-Resilient Decentralized Secure Aggregation with Groupwise Keys
Zhou Li, Xiang Zhang, Yizhou Zhao +3
This paper investigates the information-theoretic decentralized secure aggregation (DSA) problem under practical groupwise secret keys and collusion resilience. In DSA, users a…
Graph-Theoretic Characterization of Noise Capacity of Conditional Disclosure of Secrets
Zhou Li, Siyan Qin, Xiang Zhang +3
In the Conditional Disclosure of Secrets (CDS) problem, Alice and Bob hold inputs and and share a secret. Let $f:\mathcal{X}\times\mathcal{Y}\…
Hierarchical Secure Aggregation with Heterogeneous Security Constraints and Arbitrary User Collusion
Zhou Li, Xiang Zhang, Jiawen Lv +3
In hierarchical secure aggregation (HSA), a server communicates with clustered users through an intermediate layer of relays to compute the sum of users' inputs under two security…
Asymmetric Quantum Concatenated and Tensor Product Codes with Large Z-Distances
Jihao Fan, Jun Li, Jianxin Wang +2
In this paper, we present a new construction of asymmetric quantum codes (AQCs) by combining classical concatenated codes (CCs) with tensor product codes (TPCs), called asymmetric…
Construction and Performance of Quantum Burst Error Correction Codes for Correlated Errors
Jihao Fan, Min-Hsiu Hsieh, Hanwu Chen +2
In practical communication and computation systems, errors occur predominantly in adjacent positions rather than in a random manner. In this paper, we develop a stabilizer formalis…
Constructions of Pure Asymmetric Quantum Alternant Codes Based on Subclasses of Alternant Codes
Jihao Fan, Hanwu Chen
In this paper, we construct asymmetric quantum error-correcting codes(AQCs) based on subclasses of Alternant codes. Firstly, We propose a new subclass of Alternant codes which can…
