Strengthen message authentication in decentralized storage CDN consistency protocols by integrating Merkle proofs with ZKPs (e.g., zk-SNARKs) to verify cache updates without exposing data. Use AES-256 for on-wire encryption and TLS 1.3 for secure transport. Implement versioned URLs (e.g., /file.png?v=2) to force cache invalidation. Adopt real-time CDN refresh APIs (e.g., Alibaba Cloud’s URL purge) to synchronize state across nodes instantly.
