Intelligent Data Encryption Scheme for Light Weighted AIoT Enabled Devices

Abstract

The proposed cipher scheme was based on the Hill cipher scheme for the light-weighted Artificial intelligence-based Internet of Things (AIoT) enabled encrypted device in wireless sensor networks. Hill cipher breaks down easily because the Hill cipher scheme is implemented on the matrix. In this cipher scheme, the appropriate key encrypts the message and using this key the inverse key is found which decrypts the message. Hill cipher scheme is vulnerable to the known plain-text attack. To overcome this problem the proposed cipher scheme has many phases. In the first phase, the key chooses a 3 x 3 matrix and the message is multiplied with the key after which mod 128 is taken. The proposed cipher scheme is based on ASCII value. In the 2nd phase, the cipher-text is converted into binary form and the row, column positions are shifted. In the last phase, XOR operation is carried out with a random number for light-weighted encrypted devices. The results have shown that there was no error found in enciphering and deciphering the message, a lot of randomnesses have been found in the proposed Intelligent Data Encryption Scheme for Light Weighted AIoT Enabled Devices cipher-text as compared to the plain-text.
