In recent years, more and more multimedia data are generated and transmitted in various fields. So, many encryption methods for multimedia content have been put forward to satisfy various applications. However, there are still some open issues. Each encryption method has its advantages and drawbacks. Our main goal is expected to provide a solution for multimedia encryption which satisfies the target...
The H.264 Advanced Video Coding (H.264/AVC) standard is considered to be the most commonly used format for video compression. Although it supports a very broad applications range covering all forms of digital compressed video, the confidentiality of the encoded content needs enhancements. The present work proposes a new selective encryption scheme with multiple security levels. In fact, depending...
In this paper we present the design considerations of lightweight encryption algorithm. Our aim is to demonstrate how to achieve lightweight block ciphers efficient software performance for low-resource embedded devices. Several lightweight block ciphers are proposed; we selected the most recent and suitable for low-resource embedded systems such as RFID tags. In this work, we analyzed the software...
