When a gateway is first deployed:
1. Authenticates with Infisical using machine identity token
2. Receives SSH certificates for proxy server authentication
3. Establishes SSH reverse tunnel to assigned proxy server
4. Certificate issuance varies by proxy configuration:
- **Infisical-managed proxy**: Receives Instance proxy SSH client certificate + Instance proxy SSH Server CA
- **Customer-deployed proxy**: Receives Organization proxy SSH client certificate + Organization proxy SSH Server CA

Gateway ↔ Relay Server communication uses SSH certificate authentication:
- **Gateway Authentication**:
- Presents SSH client certificate (Instance or Organization proxy SSH Client CA)
- Presents SSH client certificate (Instance or Organization relay SSH Client CA)
- Certificate contains gateway identification and permissions
- Proxy server validates certificate against appropriate SSH Client CA
- Relay server validates certificate against appropriate SSH Client CA
- **Proxy Server Authentication**:
- Presents SSH server certificate (Instance or Organization proxy SSH Server CA)
- **Relay Server Authentication**:
- Presents SSH server certificate (Instance or Organization relay SSH Server CA)
- Gateway validates certificate against appropriate SSH Server CA
