Adapting and accelerating the Stream Cipher Algorithm "RC4" using "Ultra Gridsec" and "HIMAN" and use it to secure "HIMAN" Data

Masquerade attacks pose a serious threat for cloud system due to the massive amount of resource of these systems. Lack of datasets for cloud computing hinders the building of efficient intrusion detection of these attacks. Current dataset cannot be used due to the heterogeneity of user requirements, the distinct operating systems installed in the VMs, and the data size of Cloud systems. This paper presents a Cloud Intrusion Detection Dataset (CIDD)that is the first one for cloud systems and that consists of both knowledge and behavior based audit data collected from both UNIX and Windows users. With respect to current datasets, CIDD has real instances of host and network based attacks and masquerades, and provides complete diverse audit parameters to build efficient detection techniques. The final statistic tables for each user are built by Log Analyzer and Correlator System (LACS) that parses and analyzes user’s binary log files, and correlates audits data according to user IP address(es) and audit time. We describe in details the components and the architecture of LACS and CIDD, and the attacks distribution in CIDD. Nowadays, a lot of researchers did their best to accelerate the cryptographic algorithms and develop high performance cryptographic schemes by using approaches such as the use of high end computing hardware. Grid computing is one of the most powerful techniques that can achieve a high acceleration for cryptographic algorithms, also it is known that security attributes are pretty difficult to meet but security becomes even a bigger challenge when talking about Grid Computing. So the main focus of this paper is the acceleration of stream cipher algorithm "RC4" using grid technology and also providing secure communication between elements of the Grid system by encrypting data passes between them using the new accelerated RC4 Scheme without affecting the performance of the grid middleware, comparable to the actual execution time. So 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 will be accelerated by about 873.52% comparable to that accelerated by "GRIDCRYPT" Scheme that applied by "Alchemi" middleware developed by Melbourne University. Second, the use of the accelerated RC4 scheme to secure communication between elements of "HIMAN", taking into consideration that the stream ciphering algorithms like RC4 are the most suitable encryption algorithms for applying inside "HIMAN" as we will show.
