Biography
I’m Enhao, a researcher and builder working at the intersection of AI security and intelligent systems.
I am a PhD student in Computer Science and Technology at Zhejiang University, advised by Prof. Kui Ren at the State Key Laboratory of Blockchain and Data Security. I received my B.E. in Information Security from Zhejiang University in 2026.
My research focuses on intrinsic security of LLM agents, model watermarking and intellectual property protection, backdoor defense, and trustworthy AI systems.
Alongside research, I co-founded Hangzhou Zhulong Zhiyuan Technology Co., Ltd. in 2024 to bring intelligent agents into real-world use.

Intrinsic Security Defense Technologies for LLM Agents
Principal InvestigatorFocusing on intrinsic security risks in LLM agents, this project develops a three-layer active defense framework spanning the full perception–reasoning–action pipeline.
SRTP
SRTP National Innovation Project
Universal and Harmless Model Watermarking
Principal Investigator · Completed with ExcellenceThis project developed domain-embedding-based model watermarking that reprograms a target model into an owner-controlled latent space. It preserves harmlessness while remaining robust against a range of model-removal attacks, and received the Best Creative Project award at the National College Student Innovation Annual Conference—one of only 12 projects nationwide.
10 papers published or accepted at international conferences including KDD, WWW, IEEE S&P, and ICLR. A selection of my work is listed below.
Agents & evaluation
KDD · Dataset & Benchmark Track · First Author
DMind Benchmark: Toward a Holistic Assessment of LLM Capabilities across the Web3 Domain
A holistic benchmark for evaluating LLM capabilities across nine Web3 subdomains, combining objective knowledge assessment with open-ended reasoning tasks. It introduces a contamination-aware evaluation pipeline and analyzes the accuracy, reasoning reliability, and cost efficiency of 31 leading models.
WWW · Demo Track · Co-first Author
DualMind: Towards Understanding Cognitive-Affective Cascades in Public Opinion Dissemination via Multi-Agent Simulation
An LLM-driven multi-agent simulation framework that jointly models transient affective responses and persistent cognitive beliefs in public-opinion propagation. Evaluations on 15 real-world crises show that it reconstructs opinion trajectories more faithfully than existing simulation baselines.
