Lattice Cryptography on Low-Resource Devices

Autonomous drones and unmanned robotic actuators operating in physical environments must defend against both physical tampering and wireless cyber-attacks. With quantum computing timelines constantly accelerating, standard RSA and Elliptic Curve architectures represent structural vulnerabilities.

Our team at Aethel Security, in collaboration with Vesper Autonomous Systems, has successfully compiled the **ML-DSA** (Module-Lattice-Based Digital Signature Algorithm) directly to ARM Cortex-M microcontrollers.

Practical Performance Challenges Lattice-based cryptography is computationally expensive. Signature validation requires: 1. Significant flash memory capacity to host the massive key structures. 2. Large RAM allocation for vector multiplications.

By engineering customized **NTRU-lattice optimizations** in structured Assembly code, we trimmed verification memory buffers by 44% and successfully ran authentications in under **1.8 milliseconds**, opening the pathway towards lightweight, sovereign quantum-resilient hardware attestation.
