| description | Security pattern for channel-level encryption (TLS/SSH). Use when implementing HTTPS, securing all communication between endpoints, setting up TLS connections, or when infrastructure should handle encryption transparently. Addresses "Leak action request or data in transit" problem. |
Entities set up a communication channel where ALL exchanges are encrypted. The channel infrastructure handles encryption transparently. Common implementations: TLS and SSH.
Leak action request or data in transit: Any data transmitted over the channel could be observed. Encrypt everything at the channel level.
| Role | Type | Responsibility |
|---|---|---|
| Sender | Entity | Initiates communication |
| Receiver | Entity | Receives communication |
| EndpointS | Entity | Manages sending end of tunnel |
| EndpointR | Entity | Manages receiving end of tunnel |
| CryptographerS | Cryptographic Primitive | Encrypts for Sender |
| CryptographerR | Cryptographic Primitive | Decrypts for Receiver |
| EndpointManagerS | Entity | Configures sender endpoint |
| EndpointManagerR | Entity | Configures receiver endpoint |
EndpointManagerS → [initialise(config)] → EndpointS
EndpointManagerR → [initialise(config)] → EndpointR
Sender → [action/data] → EndpointS
EndpointS ↔ EndpointR: [negotiate cipher/key] (if needed)
EndpointS → [encrypt] → CryptographerS → [{x}_k] → EndpointS
EndpointS → [{x}_k] → EndpointR (over channel)
EndpointR → [decrypt] → CryptographerR → [data] → EndpointR
EndpointR → [action/data] → Receiver

Critical: Always validate certificates
Disabling certificate validation defeats TLS security.
For web applications:
| Aspect | Encrypted Tunnel | Selective Encryption |
|---|---|---|
| Scope | All communication | Specific data |
| Control | Infrastructure | Application |
| Complexity | Lower for application | Higher for application |
| Flexibility | Less | More |
Recommendation: Use encrypted tunnel (TLS) as baseline. Add selective encryption for data that needs additional protection (e.g., encrypted at rest AND in transit).
| Misconfiguration | Risk |
|---|---|
| Certificate validation disabled | MITM attacks |
| Old TLS versions enabled | Protocol downgrade |
| Weak cipher suites | Cryptographic attacks |
| Expired certificates | Connection failures, user warnings |
| Self-signed certs in production | Trust issues |
