Abstract
Encryption is a fundamental building block for computer and communications technologies. Existing encryption methods depend for their security on unproven assumptions. We propose a new model, the limited access model for enabling a simple and practical provably unbreakable encryption scheme. A voluntary network of tens of thousands of computers each maintain and update random pages, and act as page server nodes. A sender and receiver share a random key K. They use K to randomly select the same PSNs and download the same random pages. These are employed in groups of say 30 pages to extract one time pads common to S and R. Under reasonable assumptions of an adversary´s inability to monitor all PSNs, and easy ways for S and R to evade monitoring while downloading pages, hyper encryption is clearly unbreakable. The system has been completely implemented
