Marciano da Rocha is a student in the Software Engineering course at the Federal University of Technology \u2013 Paran\u00e1, Campus Dois Vizinhos, and develops his undergraduate thesis in the area of data security, under the advisory of professors Rodrigo Tomaz Pagno and Newton Carlos Will.<\/p>\n\n\n\n\n\n\n\n
The paper accepted for publication, entitled \u201cSecure Cloud Storage with Client-Side Encryption Using a Trusted Execution Environment\u201d, presents the use of data sealing feature, provided by the Intel Software Guard Extensions (Intel SGX) technology, for file encryption. A virtual file system is created in which applications can store their data, keeping the security guarantees provided by the Intel SGX technology, before send the data to a storage provider. This way, even if the storage provider is compromised, the data are safe.<\/p>\n\n\n\n
To validate the proposal, the Cryptomator software, which is a free client-side encryption tool for cloud files, was integrated with an Intel SGX application (enclave) for data sealing. The results demonstrate that the solution is feasible, in terms of performance and security, and can be expanded and refined for practical use and integration with cloud synchronization services.<\/p>\n\n\n\n
