A New Secure Framework in MCC Using Homomorphic Signature: Application in Banking Data

Abstract

Mobile Cloud computing is a new concept, which is gaining more and more popularity, allowing users to use the services of Cloud computing by using their mobile device. Unfortunately, and despite of its various benefits, MCC faces several challenges due to resource limitations of mobile devices and several security problems. Because of these problems related to security and privacy, MCC still very limited, particularly for storing and downloading sensitive data. We propose a secure framework using homomorphic encryption to forge a robust digital signature and to encrypt data, which allows mobile users to download data from a remote private cloud server while ensuring authentication, integrity, confidentiality and privacy. Our security system is primarily dedicated to companies and organizations that use the Cloud Computing services to storage of their sensitive data and their customer's personal data in order to have more storage space, to obtain more resources, and to increase their services quality. It is proposed thereafter a security analysis and an implementation of our platform in banking data, which simulate secure banking operations. The simulation results demonstrate the efficiency and the robustness of our framework, and that it offers a high level of data security.
