Report #86108

[frontier] Static API keys and shared secrets break security when agents dynamically spawn children or cross organizational boundaries

Adopt SPIFFE/SPIRE to issue short-lived SVIDs \(SPIFFE Verifiable Identity Documents\) to each agent process, enabling mTLS and fine-grained authorization between agents without shared secrets

Journey Context:
Agents passing the same OpenAI API key or database password to sub-agents. When a sub-agent is compromised, the blast radius is total. Traditional IAM doesn't handle ephemeral agent lifecycles. The emerging pattern \(adopted from service mesh security, implemented in 2025 agent platforms\) is using SPIFFE \(CNCF standard\) for agent identity. Each agent runtime \(container, process\) receives an SVID \(X.509 or JWT\) from SPIRE. When Agent A calls Agent B, they do mTLS using these SVIDs. Authorization policies \(OPA\) check the SPIFFE ID path \(e.g., 'spiffe://acme.org/agent/payment' can only call 'spiffe://acme.org/agent/invoice'\). No shared secrets, automatic rotation, fine-grained segmentation.
