Recently, chaotic dynamics-based data encryption techniques for wired and wireless networks have become a topic of active research in computer science and network security such as robotic systems, encryption, and communication. The main aim of deploying a chaos-based cryptosystem is to provide encryption with several advantages over traditional encryption algorithms such as high security, speed...

With the rapid a advancement in multimedia technology, it has become possible to generate and transmit more and more multimedia data in military commercial and medical field. Some of these data includes some sensitive information which is required to be accessed by the intended person only. Therefore, security and privacy of these information is of prime concern today. In the last couple of yea...

During the transmission of data from sender prevents from various attacks. Public key encryption is a technique which provides encryption of data using public key. The existing technique implemented for the searching of keywords with public key encryption provides security from password Guessing attacks [1]. But the technique implemented here enables security from various attacks as fine as als...

Many of today's multimedia applications require con dential video transmission over the Internet. Appropriate encryption methods require a high computational complexity and are likely to become a performance bottleneck within software-only applications. To reduce the computational encryption e ort, partial video encryption methods have been proposed in the past. Promising approaches are based o...
