چکیده
Rapid advances in embedded systems and mobile communications have flooded the market with a large volume of multimedia data. In this chapter, the authors present a summary of multimedia compression and encryption schemes, the way they have evolved over the decades. They first discuss the traditional approach to data encryption and their extension to video encryption. Next, they present the next generation algorithms for secure multimedia delivery, namely the Joint Video Compression and Encryption (JVCE) approach and give the reader an introduction to these approaches, the underlying assumption, advantages and limitations. The authors discuss the implementation of JVCE algorithms in light of requirements of mobile devices and propose how mobile agents can facilitate such an implementation.

متن کاملDoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...
