5.2 PTERI for AI Authority
PTERI treats AI agents as principals, not tools.
A principal must have:
- Identity
- Authority
- Limits
- Accountability
With PTERI
AI agents gain:
- Cryptographic identities
- Explicit authority via signatures
- Scoped permissions
- Revocable access
And they lose:
- Static secrets
- Implicit trust
- Silent escalation
The new model
Instead of asking:
“Does this API key work?”
Systems ask:
“Does a valid signature exist for this exact intent?”
An AI agent:
- Requests an action
- Receives a scoped challenge
- Obtains explicit authorization
- Executes only what was approved
No signature → no action.
Why this matters
This model ensures:
- Every AI action is attributable
- Every action has provable intent
- Authority can be limited and revoked
- Abuse is cryptographically detectable
AI becomes auditable, not just powerful.
