| Popis: | This paper presents an image encryption scheme using modified Two-square cipher associated with Arnold map. The traditional Two-square cipher is modified to make it more secure and applicable on the image data. A new block-based scheme is considered for Arnold map to handle the images of any size. The proposed scheme is structured into a substitution-permutation framework such that it has an excessively huge key space, and the correct decoding is highly sensitive to the correct keys with their correct order. The experimental results are given to validate the feasibility and robustness of the proposed scheme. Further, the superiority of the proposed scheme is analyzed by comparing with the related work. |
