Efficient Hybrid MAES Encryption Algorithm for Mobile Device Data Security at Rest in Cloud Environment

Abstract

Mobile devices like smart phones and tablets are becoming one of the major information processing devices for users. Due to increasing use of mobile devices, the need of cloud computing in mobile devices arises. Mobile cloud computing refers to an infrastructure where data processing and storage can happen away from mobile device. While using the cloud storage services on resource constraint mobile device, the mobile user needs to ensure the confidentiality of the critical data before uploading and downloading data on the cloud storage. Keeping in view the resource limitation of mobile devices, this paper, introduces a hybrid cryptographic approach for improving the security of outsourced data to cloud. Cryptography application supports symmetric, asymmetric and hashing encryption algorithm to encrypt and decrypt data for uploading and downloading within cloud storage.
