Abstract

Cloud computing has proved its worth in different technological domains by various means. With its IAAS, PAAS and SAAS, it has adopted the concept of pay as-per-use which is very trustworthy for all types of service consumers. Cloud computing is the demand of changing time and everyday more and more service consumers of cloud services are increasing. With the continuously increasing number of consumers, cloud security is now a much big concern than ever. In spite of many advantages of the cloud computing, many organizations are still reluctant towards the adoption of this technological advancement, and unfortunately the reason is genuine. The security concerns of cloud network are even increasing along with today’s growing cloud network. These security concerns can be addressed if users encrypt the data while transmitting to the cloud with strong security algorithms. In this paper we have analyzed the performance of such strong semantically secure algorithms, namely Homomorphic Algorithms, for cloud network. As Homomorphic algorithms are very strong in terms of zero knowledge proof, these algorithms will be having wide application in near future, especially in the untrusted environment like cloud computing. We have analyzed the performance of Paillier and Benaloh Partial homomorphic Algorithms for the cloud network. The algorithms are tested on the single system and on the cloud environment as well.
