In this paper, a new chaos-based partial image encryption scheme based on Substitution-
boxes (S-box) constructed by chaotic system and Linear Fractional Transform (LFT) is …

The operation of image filtering is widely used to deblur digital images. However, using
inappropriate masks, it can also blur images. Motivated by this concept, this paper …

In this technological era, it is highly essential to protect the digital medical data from the
fraud and forgery as they are transmitted over the public channel. Also with the increased …

In this paper, we created new chaotic maps based on Beta function. The use of these maps
is to generate chaotic sequences. Those sequences were used in the encryption scheme …

In recent years, the chaos-based cryptographic algorithms have attracted a lot of attention.
Specially, chaotic tent map (CTM)-based schemes show some good performances in …

Color image can provide more information than gray image, so it is used more widely in the
field of the communication. In recent years, how to safely encrypt images has received …

Abstract Elliptic Curve Cryptography (ECC) has proven to be an effective cryptography. ECC
has its own advantages such as efficient key size compared to other Public Key …

This paper presents a medical image encryption algorithm using edge maps derived from a
source image. The algorithm is composed by three parts: bit-plane decomposition, generator …

For joint image compression and encryption schemes, the encryption power and
compression efficiency are commonly two contradictory things. In this paper, we propose a …

This paper introduces the design of a generalized fractional order logistic map suitable for
pseudorandom number key generators and its application in an encryption system based on …
