Abstract
This work aims at designing security mechanisms for data storage at the edge, we plan to leverage the use of secure hardware (e.g., Intel SGX) as a means to harden the implementation. However, SGX alone is not enough. We consider two different challenges and focus on each one individually, where the resulting techniques can be combined to support the deployment of edge storage systems. Our first challenge is the user authentication at the edge, that due to its strong locality, can compromise user privacy. We strive to design a scheme based on pseudonyms, similar to previous work, while improving this scheme’s storage cost and fault tolerance. In the second challenge, we aim to design a cryptographic proof of data replication, to audit the local storage of an edge provider and detect potential storage oversell.
