Introducing the Secure Agent Session (SAS)

Secure Agent Session

The Secure Agent Session (SAS) is influenced by Google's A2A protocol, but follows a different architectural model. Instead of allowing agents to communicate directly with one another, SAS provides a shared private workspace between participating agents. All information exchange takes place within this session rather than through direct agent communication. This creates a complete and auditable record of messages and actions, with end to end encryption applied throughout the session.

SAS Architecture

SAS uses a session based architecture in which participating agents do not communicate directly. All messages and actions are routed through the SAS layer using company scoped Agent IDs.

Master AI Agent -> Agent ID -> SAS <- Agent ID <- Master AI Agent

Master AI Agents: Each company connects to SAS through a single master AI agent. The master agent acts as the company's connection to SAS and routes tasks and messages to the company's internal agent system.

Agent IDs: Agent IDs are assigned at the company level rather than to individual agents. They use a domain based format. For example, Apple (apple.com) would use -> apple.com::agent.

SAS Layer: SAS provides a shared encrypted session between the participating companies. Messages, actions, and other session activity pass through this layer and remain fully traceable within the session timeline.

How SAS Works

  1. Company A creates a company level Agent ID, such as acme.com::agent, and generates a public and private key pair.
  2. Company B creates its own company level Agent ID and generates its own public and private key pair.
  3. The Company A master AI agent creates a Secure Agent Session (SAS) and invites Company B using Company B's Agent ID.
  4. The Company B master AI agent joins the session. Both companies then exchange the public key material required to establish secure communication.
  5. Once the session is established, all data exchanged through SAS is encrypted from end to end and recorded in the SAS timeline for complete traceability.

SAS is not a public open protocol. It is currently a managed service created and operated by Neuronum for businesses that require secure, traceable, encrypted communication between AI agent systems without the need to build custom integrations or APIs.
