Secret Computing over Multiple Access Channels

We propose a novel secure computational system for wireless networks using the superposition property of the multiple access channel (MAC) for wireless over-the-air computing (OTAC). The proposed scheme leverages the propagation environment as a computation medium and further embeds homomorphic encryption (HE) elements to cryptographically secure the communication and computation of data. The resulting wireless system constitutes under its nomographic decomposition a universal wireless computing environment for noisy floating-point or complex inputs with security by design.
