Virtual machine migration represents a new topic of research last years. In this context, we present a new system based on matching game theory to design efficient and practical migration algorithms that work well with huge numbers of VMs and servers. This strategy solves VM migration, resources managements and load balancing problems in cloud computing environment. The experimental results show that...
In this paper we present an electronic voting system based on homomorphic encryption to ensure privacy, confidentiality in the voting. Our proposal offers all the advantages of the multiplicatively homomorphic encryption cryptosystems. The proposed voting scheme is suitable for multi-candidate elections as well as for elections in which contains neutral votes.
Cloud computing has now become a major trend, it is a new data hosting technology that is Very popular in recent years thanks to the amortization of costs it induces to companies. In this paper we present the major security issues in cloud computing and we also propose a simple, secure, and privacy-preserving architecture for inter-Cloud data sharing based on an encryption/decryption algorithm which...
Cloud computing gives another meaning to the word “sharing” in the world of networks. However, it gives rise to serious security problems. One of the techniques used by the attackers is the “Cloud cartography” which aims to locate a Virtual Machine in the cloud and launch a side channel attack. In this paper we propose a new technique for locating a virtual machine in a cloud environment. For this...
