We propose a device to secure random data in analog format, so that it is taken off the digital grid. Such action will turn off the means by which remote hackers violate security. A physical “rock” manufactured through 3D printing technology, constructed on the basis of high-grade randomness, which is packed into the comprising materials of that rock. The rock functions as an oracle, and does not allow any massive copy of its content. Thus, a major claim of this Prospective is that materials science and engineering may hold the keys to the future of cryptography.
