Design of security solution to mobile cloud storage

Abstract

The cloud storage ownsadvantages in pay for use and elastic scalability. However, the data securityrisk destroysthe trustrelation between the cloud service provider and user. A direct method to avoid this problemis toencrypt databefore data stored in the cloud. Thus,without the decryption key, the leakage data cannot be decrypted. While the encryption technology is good, it is not always suitable for the mobile user. When using the mobile device, such as smart phone, to access the data that stored in cloud storage system, the performance issue should be considered, because the encryption scheme involves high workload.This paper is focus on the design of security solution to mobile cloud storage. It detailed the designprinciple, security function model, and typical deploy model. It also proposeda design case based on searchable encryptionto guide the further research. © 2012 Springer-Verlag GmbH Berlin Heidelberg.
