Configuration

All configurations are described in ORAM/include/config.h, and followings are explanations of some parameters.

#define BLOCK_SIZE 128                                                                      --> Block size (in  bytes)
#define HEIGHT 10                                                                           --> Tree Height
#define BUCKET_SIZE 333                                                                     --> Bucket size
#define EVICT_RATE 280                                                                      --> Eviction frequency
#define DATA_CHUNKS BLOCK_SIZE/sizeof(TYPE_DATA)                                            --> Data chunks
const TYPE_ID NUM_BLOCK = ((int) (pow(2,HEIGHT-1))*EVICT_RATE-1);                           --> Number of blocks
const TYPE_INDEX N_leaf = pow(2,H);                                                         --> Number of leaf nodes
const TYPE_INDEX NUM_NODES = (int) (pow(2,HEIGHT+1)-1);                                     --> Number of nodes of the tree

Build & Compile

Goto to folder ORAM/ and execute

mkdir build
cd build
cmake ..
make

which produces the binary executable file named main in build/.

Usage

Run the binary executable file main, which will ask for either Client or Server mode. In our implement, we run our scheme under two servers.

Note: Please run three instances, two for servers and one for client.
