Block-MDS QC-LDPC Codes for Information Reconciliation in Key Distribution
Lev Tauz, Debarnab Mitra, Jayanth Shreekumar +3
Quantum key distribution (QKD) is a popular protocol that provides information theoretically secure keys to multiple parties. Two important post-processing steps of QKD are 1) the…
Non-Binary LDPC Code Design for Energy-Time Entanglement Quantum Key Distribution
Debarnab Mitra, Lev Tauz, Murat Can Sarihan +2
In energy-time entanglement Quantum Key Distribution (QKD), two users extract a shared secret key from the arrival times (discretized as symbols) of entangled photon pairs. In prio…
Polar Coded Merkle Tree: Mitigating Data Availability Attacks in Blockchain Systems Using Informed Polar Code Design
Debarnab Mitra, Lev Tauz, Lara Dolecek
Data availability (DA) attack is a well-known problem in certain blockchains where users accept an invalid block with unavailable portions. Previous works have used LDPC and 2-D Re…
Polar Coded Merkle Tree: Improved Detection of Data Availability Attacks in Blockchain Systems
Debarnab Mitra, Lev Tauz, Lara Dolecek
Light nodes in blockchain systems are known to be vulnerable to data availability (DA) attacks where they accept an invalid block with unavailable portions. Previous works have use…
Overcoming Data Availability Attacks in Blockchain Systems: Short Code-Length LDPC Code Design for Coded Merkle Tree
Debarnab Mitra, Lev Tauz, Lara Dolecek
Light nodes are clients in blockchain systems that only store a small portion of the blockchain ledger. In certain blockchains, light nodes are vulnerable to a data availability (D…
Communication-Efficient LDPC Code Design for Data Availability Oracle in Side Blockchains
Debarnab Mitra, Lev Tauz, Lara Dolecek
A popular method of improving the throughput of blockchain systems is by running smaller side blockchains that push the hashes of their blocks onto a trusted blockchain. Side block…
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…
