Enhanced rail-fence cryptography algorithm using hybrid models

What is it about?

At the present time, the world needs to protect information and data, whether sent or received, as it is very necessary to achieve security goals, the most important of which is confidentiality. One of the methods used to achieve this is the use of cryptography. Cryptography is the basic concept of how to support the different objectives of security when messages sent from one side to another. Several cryptography methods have developed and used, yet the Rail - Fence is the simplest and most important cryptographic method until now. In this research an advanced encryption hybrid model is proposed which improves the security of Rail-Fence algorithm by combining it with classical cryptography algorithm like Vigenère, and Hill cipher algorithms. The main objective of this research is to obtain enhanced efficient hybrid cryptography model that consists of multilayer of classical cryptographic algorithms. The results of this research indicated that the proposed model support a high level of security and a high value of entropy =6.21/6.50 that is almost equivalent to the entropy value of some modern algorithms such as the DES entropy= 7.29/8 and the RC entropy=4 7.34/8 algorithms with highest complexity of key search space of used algorithms against of brute force attack.
