Image encryption is the most direct and effective technical means for protecting the security
of image information. Based on the space filling property of the Hilbert curve and the infinite …

Based on the combination of quaternion numbers, residual matrices, and chaotic attractors,
a new cryptosystem is proposed for multimedia processing files such as images and audio …

An improved and extended version of a quaternion-based lossless encryption technique for
digital image and communication on medicine (DICOM) images is proposed. We highlight …

Abstract Information attacks are caused due to the weaknesses in the information security.
These attacks affect the non-repudiation and integrity of the security services. In this paper, a …

In the present paper we will show a system to realize an innovative cryptographic code that
ensures a high level of security using Information Fusion (IF) techniques. In detail, we have …

This paper presents a new method for encrypting holographic information based on optical
and acoustic signals called a Virtual Optical Holographic Encryption (VOHE) system for …

In this paper we present a new quaternion-based encryption technique for color images. In
the proposed encryption method, images are written as quaternions and are rotated in a …

In this paper we look at the general problem of Multiplicative Complexity (MC) as an
essential tool for optimizing potentially arbitrary algebraic computations over fields and rings …

Biometric based personal identification is a reliable and widely accepted method for
authentication. Human 3D signature is distinct from other biometric authentication methods …

Symmetric cryptography uses the same secret key for encryption and decryption. A desirable
property of symmetric encryption is termed as avalanche effect by which two different keys …
