Encryption in Transit

The use of cryptographic protocols, primarily TLS/SSL, to secure data packets as they move between disparate components of an AI system, such as the flow from a user client to a RAG orchestrator, and from the orchestrator to a remote Vector Database or LLM provider. This prevents man-in-the-middle attacks from intercepting proprietary document chunks or sensitive user prompts during network transmission.

The use of cryptographic protocols, primarily TLS/SSL, to secure data packets as they move between disparate components of an AI system, such as the flow from a user client to a RAG orchestrator, and from the orchestrator to a remote Vector Database or LLM provider. This prevents man-in-the-middle attacks from intercepting proprietary document chunks or sensitive user prompts during network transmission.

Disambiguation

Secures data 'on the wire' during API calls, as opposed to data 'at rest' on a disk or inside a vector index.

Visual Metaphor

"An armored courier truck transporting sensitive document fragments through a public highway tunnel between two high-security facilities."
