Research Interests
Dr. Tang is broadly interested in cyber-security and distributed systems. His current research focuses on systems security and performance/cost efficiency in blockchains and decentralized applications (DApp). In the past, he worked on trusted execution environments, cloud security, multi-party computation protocols. His research generally tackles the fundamental design tradeoff between security and performance: On the one hand, he analyzes and measures large-scale deployed systems to identify, verify, and mitigate vulnerabilities. On the other hand, he optimizes performance and builds middleware on security-centric systems.
Research projects:
DApp cost efficiency: [FSE21][Middleware20][TPDS13]
Secure data outsourcing: [Middleware21][ICDE19][ACSAC14]
Distributed storage & data management: [CCGrid15][EDBT14][TPDS11][TKDE10][ICDCS09][ICDCS08]
Privacy-preserving data federation: [Bioinformatics16][TKDE15][ICDCS14][CIKM11]
Side-channel security on SGX: [Project page]
Cyber-security hands-on lab development: [blockchain labs], [SGX labs], [report@CISSE19]
