Quantum Key Distribution Approach for Cloud Authentication: Enhance Tight Finite Key

Abstract

The definite length of the key size has been a hot debate since 1940. How we are going to measure it? Most cryptographic mechanisms, such as symmetric and asymmetric cryptography, often involve the use of cryptographic keys. However, all cryptographic techniques will be ineffective if the key distribution mechanism is weak. The security of most modern cryptographic systems of key distribution mechanism is based on computational complexity and the extraordinary time needed to break the code. Quantum Key Distribution (QKD) or Quantum Cryptography is attracting much attention as a solution of the problem of key distribution; QKD offers unconditionally secure communication based on quantum mechanics. In this article we proposed the enhance method to secure the distribution key which we call enhance tight finite key scheme. We will identify either this approach it suitable with the cloud authentication mechanism.
