Secure cloud storage for convenient data archive of smart phones
Sue-Chen Hsueh, Jing-Yan Lin, Ming-Yen Lin · 2011
The importance of the data stored in the smart phones is increased as more applications are deployed and executed. Once the smart phone is damaged or lost, the valuable information treasured in the device is lost altogether. If cloud storage can be integrated with cloud services for periodical data backup of a mobile client, the risk of data lost can be minimized. However, the important data might be uncovered by a malicious third party during retrieval or transmission of information using wireless cloud storage without proper authentication and protection. Therefore, in this paper, we design an archive mechanism that integrates cloud storage, hybrid cryptography, and digital signatures to provide security requirements for data storage of mobile phones. Our mechanism not only can avoid malicious attackers from illegal access but also can share desired information with targeted friends by distinct access rights.
