Convertible Polynomial Evaluation Codes in the Merge Regime: A Skew-Polynomial Framework
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we develop an algebraic framework for merge-regime convertible codes that works directly with the polynomial-evaluation structure of the underlying codes. We charact…
Convertible Codes: MSR-to-MSR Conversion with Optimal Access and Bandwidth
Yumeng Yang, Han Cai, Xianfu Lei +1
In this paper, we study convertible codes in the merge regime and focus on the minimum storage regenerating (MSR) setting, where both the initial codes and the final code admit opt…
Locally Repairable Convertible Codes: Improved Lower Bound and General Construction
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we consider the convertible code with locally repairable property. We present an improved lower bound on access cost associated with . Then, we provide a gene…
A New Cooperative Repair Scheme with Small Finite Field for Distributed Storage Systems
Yajuan Liu, Han Cai, Xiaohu Tang
In this paper, we consider the multiple failures in the distributed storage systems under the cooperative repair model. We introduce a new cooperative repair scheme for the (n,k,d,…
MDS Generalized Convertible Code
Songping Ge, Han Cai, Xiaohu Tang
In this paper, we consider the convertible codes with the maximum distance separable (MDS) property, which can adjust the code rate according to the failure rates of devices. We fi…
Private Multiple Linear Computation: A Flexible Communication-Computation Tradeoff
Jinbao Zhu, Lanping Li, Xiaohu Tang +1
We consider the problem of private multiple linear computation (PMLC) over a replicated storage system with colluding and unresponsive constraints. In this scenario, the user wishe…
