Considering the current dependency on digital technology in modern society, protection of multimedia is highly important. Encryption vital communication, ensuring data confidentiality, authentication, integrity, and non-repudiation. Multimedia encryption-based security techniques are becoming increasingly important as they allow for secure sharing content platforms. This survey aims to review s...

In digitally modern world, the fundamental issue of multimedia data security (such as digital audio signals, images, and videos) is becoming a major concern due to the rapid development of digital communications and networking technologies. Traditional encryption schemes such as DES (Data Encryption Standard) and its equivalent perform poorly for multimedia data because of the large data size a...

Data security protection is essential for most multimedia data transmissions today. Classical multimedia content protection is dominated by symmetric encryption methods. This paper explores the possibility of public-key media content encryption. The key problem to the asymmetric selective encryption is formalized and defined as the “bounded plaintext problem”. Possible solutions to this problem...

Many research efforts for image encryption schemes have elaborated for designing nonlinear functions since security of these schemes closely depends on inherent characteristics of non-linear functions. It is commonly believed that a chaotic map can be used as a good candidate of a nonlinear component for image encryption schemes. We propose a new image encryp-tion algorithm using a large pseudo...

Conventional cryptography deals with the encryption and decryption of traditional textual data. The advent of networked multimedia systems will make continuous media streams, such as real time audio and video, increasingly pervasive in future computing and communications environments. It is thus important to secure networked continuous media from potential eavesdroppers. In this paper, we consi...

Networked multimedia applications have matured in recent years to be deployed in a larger scale in the Internet. Confidentiality is one of the primary concerns of these services for their commercial usages, e.g. in video on demand services or in video conferences. In particular, video encryption algorithms are strongly required that fulfill real-time requirements. In this paper we present the v...

In this paper we present two approaches to combine recent results of cryptographic research with the requirements of modern multimedia systems. The rst is to evaluate modern block ciphers in a JAVA{environment. The second approach is based on recent developments regarding fast Luby{Racko ciphers. Paradoxically, it deals with doing \high-bandwidth encryption with low-bandwidth smartcards". Also,...

Omnipresence of security in every application in Internet application is a clear motivation to contribute in the field of Information Security. Security is one of the most challenging aspects in the internet and network applications. Encryption is a process which is used to secure the data and the Encryption algorithms play a crucial role in efficient information security systems. Full encrypti...

In the present world when whole web is now coming on from text data to multimedia data, one of the major security concerns is the protection of this multimedia data. Image, which covers the highest percentage of the multimedia data, its protection is very important. This can be achieved by Image encryption. There are so many different techniques should be used to protect confidential image data...
