✅ ECDH Key Exchange: P-384 curve with non-extractable keys
✅ ECDSA Digital Signatures: P-384 with SHA-384 for MITM protection
✅ Enhanced Replay Protection: Sequence numbers + message IDs + timestamps
✅ Packet Padding: Hide real message sizes (64-512 bytes random padding)
✅ Anti-Fingerprinting: Traffic pattern obfuscation and size randomization
✅ Fake Traffic Generation: Invisible decoy messages for traffic analysis protection
✅ Message Chunking: Split messages with random delays
✅ Packet Reordering Protection: Sequence-based packet reassembly
✅ Rate Limiting: 60 messages/minute, 5 connections/5 minutes
✅ Enhanced Validation: 64-byte salt, session integrity checks
