Secure Data Storage on the Cloud using Homomorphic Encryption

Mohanty, Manoj Kumar (2013) Secure Data Storage on the Cloud using Homomorphic Encryption. MTech thesis.



Organizations are showing great interest in storing data on public clouds. This could be a result of the unprecedented growth of data recorded in the last few years. However the security issues associated with data storage over cloud is a major discouraging factor for potential adopters. Hence the focus of today is to find cryptographic techniques that will offer more than confidentiality. Homomorphic encryption is one such method that has interesting applications in cloud. The objective is to manage and protect the data from the users of a client organization which wants to store the data on untrusted public clouds. In this thesis a hybrid cloud framework is proposed that addresses the privacy and trust issues and provides encrypted storage with public clouds. The proposed method uses Homomorphic Encryption for protecting the user data and uses a modified file updation technique to reduce bandwidth consumption during transfer of large encrypted files.
