End-to-End Data Encryption Decoupling Security from DMZ Infrastructure

The patent extracts the encryption and decryption functions from the network infrastructure (SSL terminals, DMZ servers) and relocates them to the end devices (client and server). This removes the security vulnerability point in the middle of the network chain, as only the final destination devices handle sensitive cryptographic operations, while intermediate network elements merely transmit encrypted data without ability to access or terminate the security tunnel.

The patent segments the security function into distinct components: the client device performs encryption before transmission, the network infrastructure (including DMZ) merely transports encrypted data, and the final server performs decryption. This segmentation isolates the security-critical operations from the potentially vulnerable network middle层, allowing SSL to work reliably even through complex infrastructures like DMZ without requiring the tunnel to be terminated at intermediate points.

The patent implements self-service by having the client device automatically determine its own identity (e.g., via digital certificate) and retrieve its encryption data record (private key) from local storage. The server automatically determines the client's identity from the encrypted request, retrieves the corresponding encryption data record, and performs decryption without human intervention. This automation makes the process transparent while managing the complexity through systematic automatic operations.

The patent applies preliminary action by having encryption data records (public-private key pairs) pre-generated and stored in the devices before actual data transmission occurs. During communication, the client's identity and encryption credentials are already established, allowing the server to immediately decrypt incoming encrypted requests without needing to perform complex real-time identity verification or key management operations.
