symmetric map

[Gaurav Sharma]

Hello

I am facing problem regarding symmetric pairing on prime curve.

When I try to map using pc_map(), the output stucks.

 Kindly let me know how to on symmetric pairing?

Thanks and regards

Gaurav,

The pairing computation should not get stuck. Check that you have a working configuration and that you are calling core_init() before any other RELIC function.

Also, please note that the symmetric pairings implemented in RELIC are not considered secure anymore:

This implementation is already deprecated and will be removed in release 0.4.0, later this year.

Best,

I think he was referring to the supersingular prime pairing recently added.
Though I don't know what is going on either way.

Gaurav, can you post the CMakeCache.txt and relic_conf.h files to help
investigate the issue?
