Self-Modifiable Reversible Circuits

Self-modifiable reversible circuits are introduced. The purpose of these circuits is twofold: first, reversible circuits can reduce the energy consumption in a digital computer by orders of magnitude. Second, self-modifiable reversible circuits provide computational advantages in cybersecurity and in AI. Our focus is on integrating quantum randomness into reversible circuits that implement cryptographic algorithms. These new circuits hinder Eve listening to the hardware computations because the physical locations of the bit computations are capable of moving randomly across different parts of the circuit. These circuits are likely to hinder Eve from capturing cryptographic keys even if she uses acoustic, electromagnetic, or power cryptanalysis. At the hardware level, these circuits also provide new obfuscation tools that help keep an algorithm private.
