COLE: A Column-based Learned Storage for Blockchain Systems
Ce Zhang, Cheng Xu, Haibo Hu +1
Blockchain systems suffer from high storage costs as every node needs to store and maintain the entire blockchain data. After investigating Ethereum's storage, we find that the sto…
Distributed D-core Decomposition over Large Directed Graphs
Xuankun Liao, Qing Liu, Jiaxin Jiang +3
Given a directed graph and integers and , a D-core is the maximal subgraph such that for every vertex of , its in-degree and out-degree are no smaller…
Do the Rich Get Richer? Fairness Analysis for Blockchain Incentives
Yuming Huang, Jing Tang, Qianhao Cong +2
Proof-of-Work (PoW) is the most widely adopted incentive model in current blockchain systems, which unfortunately is energy inefficient. Proof-of-Stake (PoS) is then proposed to ta…
BU-Trace: A Permissionless Mobile System for Privacy-Preserving Intelligent Contact Tracing
Zhe Peng, Jinbin Huang, Haixin Wang +8
The coronavirus disease 2019 (COVID-19) pandemic has caused an unprecedented health crisis for the global. Digital contact tracing, as a transmission intervention measure, has show…
Budget Constrained Interactive Search for Multiple Targets
Xuliang Zhu, Xin Huang, Byron Choi +3
Interactive graph search leverages human intelligence to categorize target labels in a hierarchy, which are useful for image classification, product categorization, and database se…
Graph Learning for Combinatorial Optimization: A Survey of State-of-the-Art
Yun Peng, Byron Choi, Jianliang Xu
Graphs have been widely used to represent complex data in many applications. Efficient and effective analysis of graphs is important for graph-based applications. However, most gra…
Efficient and Optimal Algorithms for Tree Summarization with Weighted Terminologies
Xuliang Zhu, Xin Huang, Byron Choi +4
Data summarization that presents a small subset of a dataset to users has been widely applied in numerous applications and systems. Many datasets are coded with hierarchical termin…
Truss-based Structural Diversity Search in Large Graphs
Jinbin Huang, Xin Huang, Jianliang Xu
Social decisions made by individuals are easily influenced by information from their social neighborhoods. A key predictor of social contagion is the multiplicity of social context…
Cost-Effective Data Feeds to Blockchains via Workload-Adaptive Data Replication
Kai Li, Yuzhe Tang, Jiaqi Chen +3
Feeding external data to a blockchain, a.k.a. data feed, is an essential task to enable blockchain interoperability and support emerging cross-domain applications, notably stableco…
Fast Algorithms for Intimate-Core Group Search in Weighted Graphs
Longxu Sun, Xin Huang, Rong-Hua Li +1
Community search that finds query-dependent communities has been studied on various kinds of graphs. As one instance of community search, intimate-core group search over a weighted…
Parameter-free Structural Diversity Search
Jinbin Huang, Xin Huang, Yuanyuan Zhu +1
The problem of structural diversity search is to find the top-k vertices with the largest structural diversity in a graph. However, when identifying distinct social contexts, exist…
Authenticated Key-Value Stores with Hardware Enclaves
Yuzhe Tang, Ju Chen, Kai Li +2
Authenticated data storage on an untrusted platform is an important computing paradigm for cloud applications ranging from big-data outsourcing, to cryptocurrency and certificate t…
Secure Consistency Verification for Untrusted Cloud Storage by Public Blockchains
Kai Li, Yuzhe Tang, Beom Heyn Kim +1
This work presents ContractChecker, a Blockchain-based security protocol for verifying the storage consistency between the mutually distrusting cloud provider and clients. Unlike e…
vChain: Enabling Verifiable Boolean Range Queries over Blockchain Databases
Cheng Xu, Ce Zhang, Jianliang Xu
Blockchains have recently been under the spotlight due to the boom of cryptocurrencies and decentralized applications. There is an increasing demand for querying the data stored in…
PP-DBLP: Modeling and Generating Attributed Public-Private Networks with DBLP
Xin Huang, Jiaxin Jiang, Byron Choi +3
In many online social networks (e.g., Facebook, Google+, Twitter, and Instagram), users prefer to hide her/his partial or all relationships, which makes such private relationships…
Rank-Aware Dynamic Migrations and Adaptive Demotions for DRAM Power Management
Yanchao Lu, Donghong Wu, Bingsheng He +3
Modern DRAM architectures allow a number of low-power states on individual memory ranks for advanced power management. Many previous studies have taken advantage of demotions on lo…
