CryptMPI: A Fast Encrypted MPI Library
The cloud infrastructure must provide security for High-Performance Computing
(HPC) applications of sensitive data to execute in such an environment.
However, supporting security in the communication infrastructure of today's
public cloud is challenging, because current networks for data centers are so
fast that adding encryption can incur very significant overheads. In this work,
we introduce CryptMPI, a high performance encrypted MPI library that supports
communication with both integrity and privacy. We present the techniques in
CryptMPI and report our benchmarking results using micro-benchmarks and NAS
parallel benchmarks. The evaluation results indicate that the aforementioned
techniques are effective in improving the performance of encrypted
communication.Comment: Updated system description, format change
