Securing Mobile User Data in Cloud Computing Environment

Manoj M. Chavan ^[2] | Poonam V. Gupta

Abstract: Mobile Cloud Computing (MCC) combines dynamic fields of cloud computing, portable computing, wireless communication infrastructure, location services and mobile web. Using mobile cloud computing the user can access unlimited computing power and storage space. Data stored by mobile user on the cloud should be secured both from unauthorized access and cloud provider. Additionally mobile devices assessing the data are constrained in terms of resource such as storage space and computing power, so communication cost must be reduced. For securing the data stored on the cloud our proposed system uses attribute based encryption in which only the authorized user can access stored data by satisfying required attributes. Complex cryptographic operations are performed by cloud provider and trusted authority i. e manager thus relieving mobile user from heavy computational load. Whenever a user leaves group of authorized users re-encryption is performed on the encrypted data by cloud provider without intermediate decryption while preserving the integrity and privacy of user data.
