How IP Packet Encryption Works Across International Networks #306755 (License: Personal Use)

This diagram demonstrates end-to-end IP packet encryption, where the payload remains private and encrypted while the header stays public for routing. Data originates in Hong Kong, traverses the Internet cloud, and reaches a device in Paris, with encryption/decryption occurring at both endpoints. The visual emphasizes separation of public routing metadata from confidential content.

Used on educational or technical web pages explaining network security, VPNs, or TLS/SSL fundamentals; targets students, IT professionals, and developers seeking to understand secure data transmission across borders.
