Because of the excellent properties of unpredictability, ergodicity and sensitivity to their
parameters and initial values, chaotic maps are widely used in security applications. In this …

This paper presents a solution to satisfy the increasing requirement of real-time secure
image transmission over public networks. The main advantage of the proposed …

Image encryption is a useful technique for many applications, such as image content
protection, image authentication, pay-TV and data hiding. In this paper, we propose an …

In recent years, the operation efficiency of chaos-based image cryptosystems has drawn
much more concerns. However, the workload arised from floating point arithmetic in chaotic …

This paper presents a new multiple chaos-based biometric image cryptosystem for
fingerprint security. This encryption algorithm is constructed with four chaotic systems, which …

An encryption scheme for colour images using a spatiotemporal chaotic system is proposed.
Initially, we use the R, G and B components of a colour plain-image to form a matrix. Then …

A novel chaotic, permutation-substitution architecture based, grayscale images' encryption
algorithm is introduced in this paper. To reduce the redundancies of Fridrich's structure …

In this paper we have proposed a new test for pixel randomness using non-parametric
method in statistics. In order to validate this new non-parametric test we have designed an …

This paper treats different aspects of entropy measure in classical information theory and
statistical quantum mechanics, it presents the possibility of extending the definition of Von …

Security has become an important issue with the proliferation of digital communication.
Multimedia sources such as images plays an important role in security of data …
