S.G.Srikantaswamy, Dr.H.D.Phaneendra An Enhanced Practical Difficulty of One-Time Pad Algorithm Resolving the Key Management and Distribution Problem. Research Journal of Mathematics and Computer Science, 2019 3:17. A New approach in One Time Pad key management. Keywords:one time pad, random number generator, key management, key-footprint, security, cryptography, unbreakable cipher. we introduce the use of negative keys to enlarge the key space K and give related algorithms.

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. 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. Let (P,C,K,ε_k,D_k) be the One Time Pad cryptosystem. Université Marien Ngouabi, Faculté des Sciences et Techniques, BP: 69, Brazzaville, Congo A New approach in One Time Pad key management
