A Framework for Secure Cloud Computing Based on Homomorphic Encryption

Ravneet Kaur [5] | Harmandeep Singh [4]

Abstract: Cloud computing is a paradigm in which services (Iaas, Paas, Saas) are leased to the user as per imposition. cloud computing entire data resides over a set of networked resources, this data can be accessed through virtual machines like mobiles PC etc. Cloud computing reduces hardware, maintenance and installation cost. But security is major issue that prevents users for cloud computing. When we relocate data to cloud we use standard encryption technique to secure the data. But when we have to do computations on data hoarded on cloud then we have to decode data i. e. provide private key every time which is not a secure method. In this paper we have proposed a technique that enhance two security features of the cloud. One is authenticity and another is data security. Normally we check authenticity by user name and password, but here we have added one more parameters i. e. MAC address. IP address is used get location of users. Data security is improved by applying homomorphic operations on DES algorithm to encrypt the data at server side. This modified DES algorithm proves to give better results than DES algorithm in terms of performance.
