— Cloud Computing is a technology which is susceptible to a continuous development, because of its strong advantages of accessing data from any place in the world over the Internet without concerning about the infrastructure used and the problems involved by the installation and maintenance processes. The purpose of this article is to provide an overview of(More)
Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks appear to be main threats for cloud computing. The protection of cloud services against DoS and DDoS attacks is realized using Intrusion Detection Systems (IDSs).This paper aims to evaluate the experimental results of our proposed quantitative solution. The experiments are performed in(More)
Cloud computing has become one of the most demanding services over the internet. It has gained remarkable fame for past few years. But it is under the severe threats of internet security. One of the severe threats is Distributed Denial of Service (DDoS). DDoS occurs when a huge amount of packets are sent to a server from various computers. Botnet is one of(More)
For real-time applications, task scheduling is a problem of paramount importance. Several scheduling algorithms were proposed in the literature, starting from static scheduling or cyclic executives which provide very deterministic yet inflexible behaviour, to the so called best-effort scheduling , which facilitates maximum run-time flexibility but allows(More)
The paper presents a solution for designing a cache coherency state machine for a multiprocessor system with error/correcting capabilities for the unidirectional errors and the used resources implied by a FPGA implementation of our solution. The cache coherency method used is based on the MESI protocol. The implementation is realized with FPGA by using the(More)
