Obliv-C: A Language for Extensible Data-Oblivious Computation
Samee Zahur, David Evans
Cryptographic protocols
Many techniques for secure or private execution depend on executing programs in a data-oblivious way, where the same instructions execute independent of the private inputs which are kept in encrypted form
throughout the computation. Designers of such computations today must either put substantial effort into constructing a circuit representation of their algorithm, or use a high-level language and lose the opportunity to make important optimizations or experiment with protocol...
A Low-Latency, Low-Area Hardware Oblivious RAM Controller
Christopher W. Fletcher, Ling Ren, Albert Kwon, Marten van Dijk, Emil Stefanov, Dimitrios Serpanos, Srinivas Devadas
Cryptographic protocols
We build and evaluate Tiny ORAM, an Oblivious RAM prototype on FPGA. Oblivious RAM is a cryptographic primitive that completely obfuscates an application's data, access pattern and read/write behavior to/from external memory (such as DRAM or disk). Tiny ORAM makes two main contributions. First, by removing an algorithmic bottleneck in prior work, Tiny ORAM is the first hardware ORAM design to support arbitrary block sizes (e.g. 64 Bytes to 4096 Bytes). With a 64-Byte block size, Tiny ORAM...
