Efficient Oblivious Accesses
The SSRC is currently investigating how to obfuscate access patterns on the cloud. Current oblivious RAM techniques are very slow, and impractical as a result. Tor and other techniques only obfuscate access over the network, allowing a hostile server to determine what files were accessed, even if they were encrypted. We are investigating how to make them faster, in a computationally efficient manner.
This is currently a work in progress.
