A New approach in One Time Pad key management

Abstract

Let (P,C,K,e_k,D_k) be the One Time Pad cryptosystem. We consider P=C=K. In this paper, we improve the key management with introduction of the concept of mathematical key footprint to ensure the uniqueness of every generated key without storing it. We also combine the default operating system’s randomness Application Programming Interface (API) CSPRNG , with some further local system entropy parameters mainly the micro level of noise and environment brightness to enhance key generation randomness using any personal device. we introduce the use of negative keys to enlarge the key space K and give related algorithms.
