Encrypted Data Stream Identification via TLS Handshake Authentication

The patent extracts and removes the plaintext identifier component from the TLS protocol identification mechanism. Instead of using Application Layer Record Layer Plaintext Identifiers (ALPIS) that expose application information in plaintext, the solution extracts only the necessary authentication functionality through cryptographic parameters exchanged during TLS handshake, eliminating the security vulnerability while preserving identification capability.

The patent introduces an intermediary authentication mechanism using TLS handshake parameters (such as Client Random, Server Random, and cryptographic keys) as mediators. These parameters serve as secure intermediaries that enable network devices to authenticate and identify encrypted data streams without exposing plaintext application information, thus maintaining security while achieving identification.

The patent performs authentication actions preliminarily during the TLS handshake process itself. By integrating the authentication mechanism into the existing handshake protocol, the system establishes security credentials and identification parameters in advance, before actual data transmission begins. This preliminary authentication avoids the need for separate, resource-intensive authentication operations during data flow processing.

The patent enables the TLS protocol to self-authenticate by utilizing authentication parameters that are inherently generated and exchanged during the handshake process. The Client Random, Server Random, and derived cryptographic keys serve as self-contained authentication credentials that allow network devices to verify and identify encrypted streams without requiring external authentication infrastructure or additional computational overhead.
