An Improved Implementation of Rip van Winkle Cipher Using Satellite TV Broadcast Transmissions

Abstract

In 1992, when Rip van Winkle’s (RvW) cipher was first proposed, the needed infinite public source wasn’t practically available yet, and demands for large buffer memory were too high. Nowadays, with many different satellites orbiting the Earth and transmitting terabytes of digital data daily, its feasible implementations can be worked out. New security-critical systems like unmanned ships and submarines or electrical vehicle (EV) charging stations need to be properly protected, because of danger of possible remote hijacking attacks. Security of present standard encryption methods like AES or RSA has already been disputed. In the wake of constant development and improvements on quantum computers and code-breaking algorithms specifically designed for them, stronger encryption methods need to be devised. This paper presents a method of practical implementation of RvW cipher, with several thousand bits strong symmetric encryption keys regenerated daily. The mathematical simplicity and provable strength of one-time pad (OTP) cipher, combined with simple key generation and synchronization method (with both forward and backward security), using one-way simplex broadcast communication only, will provide much stronger encryption.
