Ensure Security of Data in Storage Nodes in Cloud
I Mr · 2014
Personal data stored in the Cloud may contain account numbers, passwords, notes, and other important information that could beused andmisused by amiscreant, a competitor, or a court of law. These data are cached, copied, and archived by Cloud Service Providers(CSPs), often without users’ authorization and control. Self-destructing data mainly aims at protecting the user data’s privacy. All thedata and their copies become destructed or unreadable after a user-specified time, without any user intervention. In addition, the decryp-tion key is destructed after the user-specified time. In this paper, we present SeDas, a system that meets this challenge through a novelintegration of cryptographic techniques with active storage techniques based on T10 OSD standard. We implemented a proof-of-con-cept SeDas prototype.
