Advanced Cryptographic Technique Using Double Poin t Crossover

Abstract

In this paper a cryptographic algorithm is introduced. This technique uses two keys for encryption and decryption. The technique is generated intermediate cipher followed by genetic function double point crossover to produce final cipher. Square matrix is used to put the input stream in a unique manner. Left diagonal’s positional value will be the key 1 and with that key intermediate cipher text will be produced. Double point crossover is applied on the binary field of intermediate cipher text. Before doing the crossover 5 digit random number will generate as key2. According to the digit of key 2 block division process and crossover point is finalized to produce final cipher. Reverse procedure with keys will generate plaintext.
