Runtime Authorization Consistency Checking for MCP-based Agentic Workflows
Aiyao Zhang, Xiaodong Lee, Zhixian Zhuang +1
Agentic systems increasingly fulfill user requests through multi-step tool workflows over files, services, and external resources. In these workflows, isolated per-call checks can…
POLARIS: Cross-Domain Access Control via Verifiable Identity and Policy-Based Authorization
Aiyao Zhang, Xiaodong Lee, Zhixian Zhuang +3
Access control is a security mechanism designed to ensure that only authorized users can access specific resources. Cross-domain access control involves access to resources across…
Subspace Collision: An Efficient and Accurate Framework for High-dimensional Approximate Nearest Neighbor Search
Jiuqi Wei, Xiaodong Lee, Zhenyu Liao +2
Approximate Nearest Neighbor (ANN) search in high-dimensional Euclidean spaces is a fundamental problem with a wide range of applications. However, there is currently no ANN method…
DET-LSH: A Locality-Sensitive Hashing Scheme with Dynamic Encoding Tree for Approximate Nearest Neighbor Search
Jiuqi Wei, Botao Peng, Xiaodong Lee +1
Locality-sensitive hashing (LSH) is a well-known solution for approximate nearest neighbor (ANN) search in high-dimensional spaces due to its robust theoretical guarantee on query…
TI-DNS: A Trusted and Incentive DNS Resolution Architecture based on Blockchain
Yufan Fu, Jiuqi Wei, Ying Li +2
Domain Name System (DNS) is a critical component of the Internet infrastructure, responsible for translating domain names into IP addresses. However, DNS is vulnerable to some mali…
TwinTex: Geometry-aware Texture Generation for Abstracted 3D Architectural Models
Weidan Xiong, Hongqian Zhang, Botao Peng +4
Coarse architectural models are often generated at scales ranging from individual buildings to scenes for downstream applications such as Digital Twin City, Metaverse, LODs, etc. S…
