Practical, scalable alternative session encryption using one-time pads

1) Summary When I was smaller, a five megabyte fixed disk cost $5,000, a 300 bps modem cost hundreds of dollars, and communication links were intercepted by attaching devices to the target subscriber's local loop. From then to now there have been three great implosions: the cost of storage, the cost of bandwidth, and the cost of surveillance. The wake of the first two implosions sheared away most obstacles to using one­time pads to encrypt data in flight, and the final imposition — I mean implosion — now makes consideration of one­time pads a practical necessity. So far as assurance of confidentiality is concerned, today's block ciphers and public key cryptosystems flunk the exam. I don't know how to recover an AES key or compute the discrete logarithm of an elliptic curve element, but there exists no proof that another cannot. Moreover, encrypted communications can be recorded and stored for later attack by algorithms and devices yet to be discovered. Equally concerning is that when a significant " break " is discovered for solving either puzzle, the safety of an entire planet's communication and data dissolves like instant pudding. The world is unready to ingest so much pudding. We need balance in our cryptographic diet, and we need that balance now. In this paper, I discredit many myths concerning one­ time pads, discuss practical steps to address perceived shortcomings, and shatter the notion that secure generation, distribution, and use of mammoth cryptographic keys cannot be practiced in every home, church, school, and business. I also discuss my own implementations, their capabilities and track record, and where they should lead. 2) Background Interest in one­time pads (OTPs) is not new, even for me. This research marks the third time in fifteen years that I have devoted 100% of my professional time for some weeks or months to advancing their practicality and adoption. Despite my best effort and good intentions, I have not done nearly enough, and my safety as well as the safety of our world both demand that I think on a larger scale than months and weeks. It turns out that one­time pads have a 130 year history that I can trace. American Civil War veteran Frank Miller invented one­time pads in 1882 for securing telegraphy. No pun intended, but frankly anyone who tells you that OTPs can't be distributed conveniently is a wuss. Miller would have told you …
