Scalable One-Time Pad --- From Information Theoretic Security to Information Conservational Security

Wen-Ran Zhang

Abstract

Whereas it is widely deemed an impossible task to scale One-Time Pad (OTP) without sacrificing information theoretic security or network traffic, this paper presents a paradigm of Scalable OneTime Pad (S-OTP) ciphers based on information conservational computing/cryptography (ICC). Applicability of the new paradigm is analysed. It is shown that ICC enables data compression with quantumfuzzy collective precision to reduce key length to a minimum that used to be deemed impossible. Based on ICC, it is shown that, with a local IEEE binary64 standard computer associated with quantum key distribution (QKD), S-OTP enables secure transmission of long messages or large data sets with significant traffic reduction for post-quantum cryptography. Quantum crypto machinery is proposed. Some open topics are identified for further investigation
