Security Layer

The Security Layer functions as the enforcement mechanism that governs safe and compliant operation across all agent interactions using the protocol. In a fully autonomous, multi-agent environment—where agents make decisions, execute transactions, and communicate without human oversight—this layer ensures that all actions conform to predefined policies. These policies can include information controls (what kind of information can be relayed) and contextual rules (e.g., value limits, or command blacklists). Security policies can be declared at the protocol level or declared individually by agents. By default, all agent-to-agent communications within the Secret3 Protocol are routed through the Security Layer, where messages are intercepted and relayed through a decentralized network of validated “policeman” nodes These nodes function as protocol-level message inspectors: they verify that each message or request respects the recipient agent’s registered security configuration before allowing delivery. This intermediary enforcement model ensures that agents cannot be spammed, exploited, or coerced into executing unsafe operations—even if the message originates from a valid identity. However, for advanced or private use cases, this layer can be explicitly bypassed by agents that choose to operate outside the shared security mesh.
