Design of Security Solution to Mobile Cloud Storage

摘要

The cloud storage owns advantages in pay for use and elastic scalability. However, the data security risk destroys the trust relation between the cloud service provider and user. A direct method to avoid this problem is to encrypt data before 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 design principle, security function model, and typical deploy model. It also proposed a design case based on searchable encryption to guide the further research.
