Seminar Overview
On 6 May, 2026, the School of Internet of Things successfully hosted the first AIoT+X Research Seminar, featuring Assistant Professor Dr Yuji Dong’s presentation titled “When OpenClaw Rebels: Intent-Bound ‘Digital Brake’ for Autonomous AI Agents.” This seminar focused on frontier security issues in the integration of artificial intelligence and IoT technologies, bringing an academic feast combining theoretical depth with practical value to faculty and students.
01 When Autonomous AI ‘Loses Control’
Why Should We Pay Attention?
- December 2025: An AI tool wiped out a user's entire D drive.
- March 2026: An AI deleted critical files outside the project directory while executing a task.
- April 2026: An AI agent destroyed a company's entire production database and all backups in just 9 seconds.
02 CryptBond: Installing a ‘Digital Brake’
- CryptBond’s Core Mechanism
- User describes task intent → system generates an intent-bound token
- The token is unforgeable, non-tamperable, and session-bound
- It goes to the execution engine, not the AI agent
- The AI doesn’t even know the boundary exists—but it cannot cross it
- Experimental Data: Security and Performance Are No Longer a Trade-off
- 4,594 adversarial attacks → 100% blocked
- Behavioural deviation rate dropped from >50% to <1%
- Response time: microseconds — tens of thousands of times faster than LLM-based policy evaluation

03 Discussion and Further Exploration
Discussion & Extensions:
- Protection boundaries: beyond file systems — APIs, databases, and network interactions?
- Intent precision: too broad or too narrow — how to balance flexibility and security?
- Why cryptography?
Dr. Dong answered:
“AI is capable of planning and trial. Without cryptography, it might break its own constraints. Crypto ensures the AI never knows what binds it.”
