Concentrated Stopping Set Design for Coded Merkle Tree: Improving Security Against Data Availability Attacks in Blockchain Systems
Debarnab Mitra, Lev Tauz, Lara Dolecek
In certain blockchain systems, light nodes are clients that download only a small portion of the block. Light nodes are vulnerable to data availability (DA) attacks where a malicio…
Hierarchical Coding for Cloud Storage: Topology-Adaptivity, Scalability, and Flexibility
Siyi Yang, Ahmed Hareedy, Robert Calderbank +1
In order to accommodate the ever-growing data from various, possibly independent, sources and the dynamic nature of data usage rates in practical applications, modern cloud data st…
Spatially Coupled Codes with Sub-Block Locality: Joint Finite Length-Asymptotic Design Approach
Homa Esfahanizadeh, Eshed Ram, Yuval Cassuto +1
SC-LDPC codes with sub-block locality can be decoded locally at the level of sub-blocks that are much smaller than the full code block, thus providing fast access to the coded info…
Efficient Information Reconciliation for Energy-Time Entanglement Quantum Key Distribution
Siyi Yang, Murat Can Sarihan, Kai-Chi Chang +2
Graph based codes such as low density parity check (LDPC) codes have been shown promising for the information reconciliation phase in quantum key distribution (QKD). However, exist…
Non-Uniform Windowed Decoding For Multi-Dimensional Spatially-Coupled LDPC Codes
Lev Tauz, Homa Esfahanizadeh, Lara Dolecek
In this paper, we propose a non-uniform windowed decoder for multi-dimensional spatially-coupled LDPC (MD-SC-LDPC) codes over the binary erasure channel. An MD-SC-LDPC code is cons…
Topology-Aware Cooperative Data Protection in Blockchain-Based Decentralized Storage Networks
Siyi Yang, Ahmed Hareedy, Robert Calderbank +1
From currency to cloud storage systems, the continuous rise of the blockchain technology is moving various information systems towards decentralization. Blockchain-based decentrali…
