“…Bhunia [5][6][7] proposed the Automatic Variable Key technique for practical approaches of security in the year 2006. There are many researchers like Goswami [10][11][12][13][14][15][16][17], Banerjee and Dutta et al [8][9] invented more secure techniques based on Automatic Variable Key (AVK) by increasing the randomness, standard deviation and root mean square among the auto generated key sequences. The aim of our techniques is to secure the key from unauthorized persons and tom hide the secret keys from others and to generate more random keys as compared to the existing key generation techniques.…”
