Deadline: 24-Mar-2026
The Advanced Research and Invention Agency (ARIA) is funding ambitious R&D projects to strengthen secure agent-to-agent interactions in untrusted environments. Through its Scaling Trust Programme, ARIA supports open-source tooling and fundamental research that enables provable AI security, protocol verification, and cyber-physical trust primitives. Applications close on 24 March 2026 at 14:00 GMT.
Programme Overview
The Advanced Research and Invention Agency (ARIA) is accepting applications under its Scaling Trust Research and Development Grant Programme. The initiative aims to build secure, trustworthy multi-agent systems capable of operating in adversarial or untrusted digital and cyber-physical environments.
The programme focuses on two main pillars:
• Open-source tooling for agent coordination and security
• Foundational research that converts empirical AI security into provable guarantees
The objective is to deliver real-world demonstrations, measurable trustworthiness, and high-impact adoption across academia and industry.
What Problem Is ARIA Addressing?
As AI agents increasingly negotiate, coordinate, and act autonomously, secure agent-to-agent interaction becomes critical. In untrusted environments, agents must:
• Translate vague human intent into formal security requirements
• Negotiate collective policies
• Generate and verify secure protocols
• Provide auditable execution records
ARIA’s Scaling Trust Programme aims to establish theoretical and practical foundations that ensure these processes are verifiable, secure, and interoperable.
Programme Structure: Three Interlinked Tracks
Although the programme includes three tracks, this funding call targets Track 2 and Track 3.
Track 1: Arena (Testing Environment)
A live adversarial environment where tools and research outputs are stress-tested.
Track 2: Tooling (Open-Source Infrastructure)
Supports development of reusable open-source components for secure agent coordination.
Track 3: Fundamental Research
Develops theoretical foundations and new security primitives for AI agent systems.
Track 2: Tooling (Open-Source Agent Infrastructure)
Track 2 funds the development of open-source agents and reusable components that act as baseline participants in the Arena.
Eligible Technical Areas
• Requirement gathering tools that convert ambiguous user input into formal security policies
• Negotiation engines that derive shared collective policies
• Security reasoning systems that generate and implement secure protocols
• Reporting and auditing tools that convert execution traces into concise compliance statements
Expected Project Outcomes
Projects must demonstrate:
• Competitiveness within the Arena
• Generality across multiple tasks
• Computational efficiency
• Evidence of community adoption
Funding and Duration
• £200,000 to £2 million per project
• Project duration: 3 to 12 months
• 4 to 6 teams expected to be funded
Track 3: Fundamental Research
Track 3 advances scientific confidence in AI agent security and coordination through theoretical and experimental research.
Core Research Areas
• Formal AI Security with provable guarantees
• Cyber-Physical Trust Primitives using physical or biological trust anchors
• Foundations of Generative Security for automated protocol creation and verification
• Bluesky research exploring novel or unforeseen theoretical challenges
Funding and Duration
• £100,000 to £3 million per project
• Project duration: 6 to 18 months
• 3 large research centres plus smaller exploratory teams
All outputs must be openly published to seed research communities and inform future Arena challenges.
Open-Source and Ecosystem Requirements
All funded software and research outputs must:
• Be released under permissive open-source licences
• Ensure transparency and interoperability
• Support long-term ecosystem growth
The programme operates through iterative phases including bootstrap, testing, improvement, and scaling, with quarterly milestones, check-ins, build weeks, and hackathons.
Who Is Eligible?
ARIA encourages applications from:
• Research institutions
• Universities
• Startups and technology companies
• Open-source developers
• Interdisciplinary AI security teams
Non-UK teams may be funded if they significantly enhance UK benefit and ecosystem impact.
