Intent-Bound Authorization (IBA)

The baseline security requirement for autonomous AI systems.

Autonomous action without intent-binding is ungovernable by design.

Traditional authorization asks "who can do what." For autonomous agents generating novel action sequences, this isn't enough. IBA binds authorization to purpose and makes the unpredictable governable.

🚨 The Problem

In 2024, autonomous AI agents executed $3.8B in unauthorized transactions—not through hacking, but through legitimate credentials.

Every attack succeeded because systems asked:

• ✅ "Who are you?" (Authentication)
• ✅ "What can you do?" (Authorization)
• ❌ "WHY are you doing this?" (Intent)

Traditional auth cannot constrain agents it cannot predict.

✅ The Solution

Intent-Bound Authorization consists of four essential layers:

1. Intent Declaration - Structured purpose statements with cryptographic signatures
2. Cryptographic Binding - Unforgeable verification using Ed25519
3. Runtime Validation - Continuous drift detection during execution
4. Automatic Revocation - Intent expires on completion or violation

🚀 Quick Start

Installation

pip install iba-agentic-security

5-Minute Example

from iba import IntentDeclaration, IntentScope, IntentValidator

# Define what the agent can do
scope = IntentScope(
    allowed_resources=["calendar:read", "calendar:write", "booking:create"],
    forbidden_resources=["medical_records:*", "payment:*"]
)

# Declare the agent's purpose
intent = IntentDeclaration(
    intent_id="appointment-001",
    declared_purpose="Schedule dentist appointment for next Tuesday",
    authorized_by="user@example.com",
    scope=scope
)

# Validate actions in real-time
validator = IntentValidator(intent)

# ✅ Legitimate action - ALLOWED
result = validator.validate_action("search", "calendar:read")
print(result['allowed'])  # True

# ❌ Malicious action - BLOCKED
result = validator.validate_action("access", "medical_records:patient_data")
print(result['allowed'])  # False
print(result['reason'])   # "Resource medical_records:patient_data is explicitly forbidden"

That's it. The agent can only execute actions aligned with its declared purpose.

💡 Real-World Example: Wormhole Prevention

The $600M Wormhole bridge exploit succeeded because traditional auth asked "WHO can do WHAT" but never "WHY is this being done?"

How IBA Would Block It

scope = IntentScope(
    allowed_resources=["token:swap"],
    resource_limits={"max_usdc_transfer": 100, "max_eth_transfer": 0.05}
)

intent = IntentDeclaration(
    intent_id="swap-001",
    declared_purpose="Swap 100 USDC for ETH",
    scope=scope
)

# Malicious contract attempts massive drain
result = validator.validate_action("transfer", "120000_ETH")
# ❌ BLOCKED: Exceeds declared scope
# 🛡️ $600M saved

🔧 MCP Integration Example

from iba import IntentDeclaration, IntentScope
from examples.mcp_integration import IBAMCPServer

# Create intent-bound MCP server
server = IBAMCPServer(intent)

# Register tools with resource mappings
server.register_tool("search_dentists", search_func, "healthcare:search")

# All tool calls validated against intent
result = server.call_tool("search_dentists", {"location": "SF"})
# ✅ Allowed - aligns with purpose

result = server.call_tool("access_medical_records", {"patient_id": "123"})
# ❌ Blocked - violates intent

See examples/mcp_integration.py for complete demo.
