CryptMPI: A Fast Encrypted MPI Library

 As more #HPC applications move to cloud infrastructure, securing and protecting HPC sensitive data in such an environment becomes critical.

But HPC solution tends to fall short when it comes to security. Security features tend to be perceived as detrimental to the performance of the applications.

By example, encrypted communication has always been seen as incurring very significant overheads when you are aiming for microsecond latency.

The author of the Crypt MPI paper demonstrates that you can ensure the privacy and integrity of sensitive data with minimal performance degradation using an enhance MPI library.

I hope to see this kind of feature integrated as standard in a future version of MPI.
