Cryptographic technique by square matrix and single point crossover on binary field

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 single point crossover to produce final cipher. Squire 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. Single point crossover is applied on the binary field of intermediate cipher text. Before doing the crossover 5 digit random number will generate as key 2. 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 plain text.
