DRUGHUB announces comprehensive security hardening across all infrastructure layers. This upgrade addresses emerging threats in onion routing, strengthens PGP workflows and eliminates remaining metadata leakage vectors.
Enhanced threat protection
Key improvements deployed
Circuit padding
Randomized padding eliminates traffic pattern analysis. All circuits maintain constant bandwidth regardless of content.
PGP nonce rotation
Session-specific nonces prevent replay attacks. Each login challenge uses unique cryptographic material.
Timing obfuscation
Artificial delays normalize response times. Eliminates timing-based correlation between user actions.
Implementation details
The upgrade maintains backward compatibility while introducing these hardening measures:
- Zero downtime deployment via blue-green onion rotation
- All existing PGP fingerprints remain valid
- Multisig escrow contracts unchanged
- Vendor authentication flows preserved
"Security isn't a feature—it's the foundation. This upgrade doesn't add new capabilities, it removes attack surfaces."
