Randomized Experiments

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Random Error

Random Error

Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Area of Science:

Computer Science
Cryptography
Information Security

Background:

Transmitting multiple images in batches over unsecured networks requires robust and secure encryption.
Existing single-image encryption methods struggle with large data volumes.
The need for efficient multiple-image encryption (MIE) techniques is growing.

Purpose of the Study:

To introduce a novel three-layer MIE technique for batch image encryption.
To enhance security and efficiency in transmitting multiple images.
To address the limitations of single-image encryption for large datasets.

Main Methods:

A three-layer encryption process involving RGB channel separation, randomization, and chaotic map-based scrambling and diffusion.
Utilizes Baker, Henon, and 2-D Logistic chaotic maps for generating chaotic sequences.
Employs XOR operations for the diffusion process.

Main Results:

The proposed scheme demonstrates high efficiency and security through various analyses (key sensitivity, key space, complexity, entropy).
Tests including correlation, MSE, PSNR, UACI, and NPCR validate the encryption's effectiveness.
Experimental results confirm the technique's confidentiality and resistance to attacks.

Conclusions:

The novel three-layer MIE technique provides robust confidentiality and strong resistance against various attacks.
The method is suitable for secure batch image transmission over unprotected networks.
The proposed encryption scheme effectively manages large volumes of image data.
