Double Layer Perceptron Synchronized Computational Intelligence Guided Fractal Triangle Based Cryptographic Technique for Secured Communication (DLPFT)

In this paper, a double layer perceptron session key guided fractal triangle based encryption (DLPFT) has been proposed. In this proposed DLPFT technique identical double layer perceptron is used in both sender and receiver side. Triangularized approach using fractal is exploits to encrypt the plain text for producing level 1 i.e. fractal triangle encrypted cipher text. Now, level 1 cipher text is selected to accomplish level 2 encryption i.e. double layer Perceptron (DLP) generated session key based encryption to produce final cipher text. This final cipher text gets transmitted to the receiver. Receiver side has same DLP synchronized session key because of mutual synchronization operation. This session key is making use of performing deciphering technique by XOR with encrypted text. Outcome of this deciphering operation is level 1 encrypted cipher text. Finally fractal triangle based technique is used to further decode the text and generate plain text from the level 1 encrypted cipher text. Parametric tests are done and results are compared in terms of Chi-Square test, response time in transmission with some existing classical techniques, which shows comparable results for the proposed system.
