mKEM for cSIDH/p512

Implementation of multi-KEM for SIKE and multi-PKE for cSIDH.

Implementation

The implementation is done in Go. Compilation requires go 1.12 or newer to compile with GO111MODULE=on. Implementation is based on cSIDH and SIDH from NOBS NOBS library.

Running and benchmarking

To run all benchmarks use following command

make run

It is possible to run only subset of benchmarks. The command make run-cycles will calculate CPU cycles for encryption/encapsulation to N users. The command make run-ns will produce results in nanoseconds.

Results

Benchmarks has been run on i7-8665U (Whiskey Lake) @ 1.90GHz
