in most applications, security attributes are pretty difficult to meet but security becomes even a bigger challenge when talking about Grid Computing. Providing secure communication between elements of a computational Grid, by encrypting data passes between them using enhanced encryption algorithms that do not affect the Performance of the grid middleware completely comparable to the actual execution time.In this paper we will cover two points. First, accelerating RC4 encryption algorithm using our developed Grid Security Scheme "ULTRA GRIDSEC" and our developed "HIMAN" middleware and show that RC4 was accelerated by about 873.52% comparable to that accelerated by "GRIDCRYPT" Scheme that applied by "Alchemi" middleware developed by Melbourne University. Second, using the accelerated RC4 scheme to secure communication between elements of "HIMAN", the stream ciphering algorithms like RC4 are the most suitable encryption algorithms for applying inside "HIMAN" as we will show.

A digital certificate scheme in content protection system for high definition digital interfaces is proposed. Before transferring the encryption content, the device interface is firstly confirmed whether it is passed the certification. After the certification, then transfers the content. The interface of the receiver detects whether the recognition management unit has passed the certification. The digital content is ensured by the recognition management unit, which can prevent the invalid capturing the information. In the period of certification, the characteristics of the certificate are fully made use of. The application shows the system is high secure, which can be used in the high definition digital interface.

This paper presents a novel, principled approach to resolve the remained problems of substitution technique of audio watermarking. Using the proposed genetic algorithm, message bits are embedded into multiple, vague and higher LSB layers, resulting in increased robustness. The robustness specially would be increased against those intentional attacks which try to reveal the hidden message and also some unintentional attacks like noise addition as well.

How to protect the video streaming for reasonable usage is a necessary technology in multimedia services over network. However, most the previous schemes are too complicated and time-consuming to apply in real multimedia content protection system. Network Coding (NC) is a new technology which codes the input information at intermediate nodes and can make the network information flow achieve the upper bound of max-flow min-cut theory. Random Linear Network Coding (RLNC) is a practical approach of NC with advantage of decentralized operation. In this paper, we proposed a novel scalable video streaming protection algorithm with an efficient packetization scheme and a distribution scheme according to authority levels of different users based on RLNC approach. The algorithm classified the packetized packets into different levels and employed three kinds of permission matrix (PM) to control the distribution of video streaming. The implementation of the proposed algorithm was described in detail to show the efficiency and low complexity of the method.
