# HotCalls

## A fast alternative interface for SGX secure enclaves

Based on ISCA 2017 HotCalls paper, that can be found at (http://www.ofirweisse.com/previous_work.html).

### Build and run tests

`make; ./test_hotcalls`

The main benchmark function is at App/App.cpp: HotCallsTester::Run()

Measurements of different type of calls are in `measurements/` directory:

- HotEcall_latencies_in_cycles.csv

- HotOcall_latencies_in_cycles.csv

- SDKEcall_latencies_in_cycles.csv

- SDKOcall_latencies_in_cycles.csv

The number of iterations is defined by `PERFORMANCE_MEASUREMENT_NUM_REPEATS` at `App/App.cpp`.

The round trip time of calls is measured in cycles, using RDTSCP insturction. The overhead of the RDTSCP insturction is roughly 30 cylces, which should be substructed from the numbers in the `csv` files. Different machines may have different overheads for RDTSCP.
