Abstract

Providing security system for every electronic data exchange through internet as the unsecured medium has become an essential regulation. Conventional Caesar Cipher had less computation complexity than other security method that really appropriate with low powered device requirement. However, it is susceptible attack by brute force attack cryptanalysis due to its simplicity calculation. Therefore, this paper proposed enhancement scheme for Caesar cipher using layered numeral calculation based on expansion, transposition, multiplication combination. Adding several processes can be provided difficult cipher and also eliminated the weakness of Caesar cipher. In this paper, cipher text output from enhanced Caesar encryption is encoded into QR code as the encrypted QR code which can be employed text data protection. According to the experiments used ESP32, this enhanced Caesar cipher only consumes about 2.34 ms which will not burden the devices while doing other processing and minimizing power usage.
