Security Layer: Encryption & KMS Integration for Memory & Traces

🔐 Security Layer: Encryption & KMS Integration

Goal: Encrypt memory embeddings and traces with KMS or Vault plugins extending agent-mesh layer.

Encryption Strategy

1. Data-at-Rest Encryption

Encrypt stored data:

• Vector embeddings in Qdrant
• Conversation history
• Agent memory
• Trace data
• Configuration secrets

2. Data-in-Transit Encryption

Secure communication:

• mTLS between services
• TLS for external APIs
• Encrypted message queues
• Secure service mesh

3. Key Management

KMS Integration

• AWS KMS for cloud deployments
• Envelope encryption
• Key rotation policies
• Access control

Vault Integration

• HashiCorp Vault for secrets
• Dynamic credentials
• Certificate management
• Audit logging
