blocks and each block is encrypted using XOR operation by four 8-bit keys. The total size of key in our algorithm is 32 bit long which proves to be strong enough. The proposed encryption …

This paper proposes a new chaotic cryptosystem for the encryption of very high-resolution digital images based on the design of a digital chaos generator by using arbitrary precision...

block-based encryption and decryption algorithm helps to reduce the relationship among image elements by increasing the entropy value of the encrypted images as well as lowering the …

In this section, the proposed image encryption method using permutation and XOR operation is presented. Initially the original gray scale image is divided into blocks of NxN. Random …

In this paper, we propose a two-phase encryption and decryption algorithms that is based on shuffling the image pixels using affine transform and they encrypting the resulting image using …

This research introduces a lightweight image encryption framework specifically designed for medical IoT devices, utilising a 6D chaotic map in conjunction with XOR diffusion, pixel...

The proposed method comprises two main phases: the first phase generates dynamic matrix secret key to be used in the second phase of encrypting each block using XOR-Operation.

the work lies in generating crucial images for encryption. The crucial image is then created with the assistance of a secret alphanumeric key. Each alphanumeric key will have an 8bit value …

Feb 25, 2025 · Here is a brief explanation of how XORbased image encryption works and how to scan. The original image is divided into a particular number of blocks. shuffled using scan …

Jun 8, 2022 · In this article, we will encrypt/decrypt an image using simple mathematical logic. It requires two things, data, and key, and when XOR operation is applied on both the operands …
