ETHDKG: Distributed Key Generation with Ethereum Smart Contracts
Distributed Key Generation DKG Ethereum
2019/8/30
Distributed key generation (DKG) is a fundamental building block for a variety of cryptographic schemes and protocols, such as threshold cryptography, multi-party coin tossing schemes, public randomne...
The Rush Dilemma: Attacking and Repairing Smart Contracts on Forking Blockchains
blockchain forks smart contracts secure computation
2019/8/6
We investigate the security of smart contracts within a blockchain that can fork (as Bitcoin and Ethereum). In particular, we focus on multi-party computation (MPC) protocols run on-chain with the aid...
A Blockchain-Based Access Control Scheme for Smart Grids
smart grids access control blockchain
2019/8/2
At present, the access control schemes in the power grid are centralized. In the centralized system, the data of the network sensor nodes is transmitted by centralized nodes, and the data itself may b...
Bitcontracts: Adding Expressive Smart Contracts to Legacy Cryptocurrencies
Blockchain Smart Contracts Cryptocurrency
2019/7/24
In contrast to traditional contracts, cryptocurrency-based smart contracts can provide improved business automation and more transparency. However, not all cryptocurrencies support expressive contract...
ACE: Asynchronous and Concurrent Execution of Complex Smart Contracts
Blockchain Smart Contracts Cryptocurrency
2019/7/22
Smart contracts are programmable, decentralized and transparent financial applications. Because smart contract platforms typically support Turing-complete programming languages, such systems are often...
A Smart Contract Refereed Data Retrieval Protocol with a Provably Low Collateral Requirement
blockchain collateral decentralized ledger
2019/5/23
We present a protocol for a cryptoeconomic fair exchange of data previously owned by the purchaser for tokens that functions even when both parties are anonymous. This enables peer-to-peer data storag...
On the Efficiency of Privacy-Preserving Smart Contract Systems

2019/5/14
Along with blockchain technology, smart contracts have found intense interest in lots of practical applications. A smart contract is a mechanism involving digital assets and some parties, where the pa...
Fast Keyed-Verification Anonymous Credentials on Standard Smart Cards
Privacy anonymous credentials authentication
2019/5/13
Cryptographic anonymous credential schemes allow users to prove their personal attributes, such as age, nationality, or the validity of a ticket or a pre-paid pass, while preserving their privacy, as ...
Blockchain-based smart contract platforms like Ethereum have become quite popular as a way to remove trust and add transparency to distributed applications. While different types of important applicat...
Smart contracts are envisioned to be one of the killer applications of decentralized cryptocurrencies. They enable self-enforcing payments between users depending on complex program logic. Unfortunate...

2018/11/15
Public-key infrastructures (PKIs) are an integral part of the security foundations of digital communications. Their widespread deployment has allowed the growth of important applications, such as, int...
Forward Secure Signatures on Smart Cards
hash-based signatures forward secure signatures smart cards
2018/11/8
We introduce the forward secure signature scheme XMSS++ and present an implementation for smart cards. It is based on the hash-based signature scheme XMSS. In contrast to the only previous implementat...
Automated Penalization of Data Breaches using Crypto-augmented Smart Contracts
Data leakage Oblivious transfer Smart Contracts
2018/11/2
This work studies the problem of automatically penalizing intentional or unintentional data breach (APDB) by a receiver/custodian receiving confidential data from a sender. We solve this problem by au...
