Nowadays, security in data transfer is of special importance. Images are of the most
attractive kinds of data in the encryption domain. Color images are more attractive than the …

With the widespread adoption of smart devices and high-speed networks, investigators are
focusing on securing digital image applications, such as those on social media, in …

In order to overcome the difficulty of key management in “one time pad” encryption schemes
and also resist the attack of chosen plaintext, a new image encryption algorithm based on …

In recent years, several algorithms of secure image encryption were studied and developed
through chaotic processes. Most of the previous algorithms encrypt color components …

In this paper, a novel algorithm for image encryption based on hash function is proposed. In
our algorithm, a 512-bit long external secret key is used as the input value of the salsa20 …

Recently, the hyperchaotic maps have been investigated in order to develop more secure
encryption schemes. In this paper we propose a new hyperchaotic map derived from …

For the asymmetric key, the Diffie Hellman Key (DHK) protocol is very efficient, but
sometimes it is vulnerable against brute force attacks if the parameters are not chosen …

Internet allows people in any corner of the world to share instantly all types of information.
Secure sharing of sensitive multimedia data necessitates confidentiality service, which is …

This paper focuses mainly on the different kinds of image encryption and decryption
techniques. In addition focuses on image encryption techniques, As the use digital …

The protection of multimedia content has become a key area of research, since very often a
user's privacy and confidentiality can be at risk. Although a large number of image …
