In present times, multimedia protection is becoming increasingly jeopardized. Therefore numerous ways of protecting information are being utilized by individuals, businesses, and governments. In this paper, we survey Salsa20 as a method for protecting the distribution of digital images in an efficient and secure way. So, we performed a series of tests and some comparisons to justify salsa20 eff...

Search protocols are among the main applications of RFID systems. Since a search protocol should be able to locate a certain tag among many tags, not only it should be secure against RFID threats but also it should be affordable. In this article, an RFID-based search protocol will be presented. We use an encryption technique that is referred to as authenticated encryption in order to boost the ...

Due to highly increase of enhanced computer and communications between them and also dramatic increase in electronic media, security plays an important role for those organizations where the data is very much critical and important for them. As multimedia is the most popular data shared in the web so it is very much required for the protection over it through an advanced encryption technique so...

The role of multimedia and user interactivity has increased in recent years. User interaction is an important component of emerging multimedia systems, and the methods of interaction will become increasingly complex as they are being used in more diverse applications. One such application is surveillance, both in the civil as well as the military domain. The real-time three-dimensional stereovi...

Distributed multimedia applications require a variety of communication services. These services and different application demands have to be provided and supported within end-systems in an efficient and integrated manner, combining the precise specification of Quality-of-Service (QoS) requirements, application interfaces, multicast support, and security features. The Da CaPo++ system presented ...

Distributed platforms for live and on-demand media streaming delivery such as content distribution networks and media ondemand systems, are being diffused mainly due to the widespread availability of IP-based, bandwidth-capable digital networks. Provision of multimedia group services is usually supported by transmitting media streams to subscribers organized in a multicast group. Although multi...

With the rapid growth of the Internet and multimedia systems in distributed environments, it is easier for digital data owners to transfer multimedia documents across the Internet. Therefore, there is an increase in concern over copyright protection of digital contents [Piva et al (2002); Lu et al (2001); Lu et al (2000); Lee and Jung (2001)]. Traditionally, encryption and control access techni...

In order to efficiently encrypt multimedia streams delivered in real-time environments, a Fast Encryption Algorithm for Multimedia (FEA-M) was proposed [8, 9]. Cryptanalyses of this technique [1, 3, 4, 5] have identified its weaknesses and an improved variant has been suggested in [5]. In this paper, we identify further weaknesses in the original FEA-M and also in the improved variant. Our solu...

Selective encryption is a concept in which the main goal is to reduce computational cost while providing confidentiality by encrypting only chosen parts of the information to be protected. Previous work on selective encryption has mainly been aimed towards multimedia applications in order to reduce the overhead induced by encryption while still making the information perceptually secure to a de...
