Traditional RSA and ECC encryption used in TLS and API authentication are vulnerable to quantum attacks via Shor's algorithm, putting high-value AI assets like model weights and training sets at risk. The recommended approach is crypto-agility: adopting hybrid encryption combining AES-256 with NIST-approved post-quantum algorithms like ML-KEM (Kyber). The Model Context Protocol (MCP) introduces an additional attack surface that legacy WAFs and API gateways cannot inspect. A three-step roadmap is outlined: audit HVLL data, hybridize encryption, and deploy protocol-aware monitoring agents. ## Full article daily.dev links to this article rather than hosting it.
