Lattice-based Cryptographic Integration for MCP Host-Client Communication

This blog post outlines how hardware-backed eSIMs combined with lattice-based (post-quantum) cryptography can provide a secure root of trust for MCP-based AI-to-device communication, contrasts hardware anchors with cloud simulation for testing, and recommends operational controls—such as hybrid visibility, unified audit logs, parameter-level restrictions, and real-time tool verification—to mitigate risks like identity spoofing, tool poisoning, and puppet attacks.
