Novel location permutation encryption based on exponential numbers

The pattern of exponential number can achieve 99% ideal uniformity distribution level and is characterized with quasirandom nature. In this study exponential pattern is modified to possess an ideal uniform distribution property for operating location permutation. Cipher space of the proposed permutation scheme can achieve its factorial function upper bound. Brute-force restoration of permutation belongs to factorial complexity order which is more complex than exponential function. The proposed encryption scheme belongs to lightweight cryptographic function that is applicable to internet of things (IoT). This novel encryption technique can outperform the advanced encryption standard (AES) from the simplicity of algorithm, the availability, generation and distribution of long encryption key, and high confidentiality level points of view.
