Cloud Storage Third-Party Data Security Scheme Based on Fully Homomorphic Encryption
Junjian Chen · 2016
Cloud storage, which is an architecture based on Internet, has a strong demand on data stored in the cloud servers. As the application area of cloud storage expands, problems about its third-party data security become more and more prominent. Based on the analysis of cloud storage services architecture, we propose a third-party data security solution based on fully homomorphic encryption, which is a recent breakthrough in cryptography, and can process the encrypted data through fully homomorphic transformation, thus solves the third-party cloud storage data privacy problems well. If anomaly detection or processing can be done on the encrypted data, it will have great commercial values. Our solution can assist filter to confirm encrypted junk e-mails and make it possible for users to fetch information from the search engines without exposing the content of the request. Both these can't be done by conventional security solutions, so our solution greatly promotes the development of security technologies in the cloud storage.
