Random matching mentor and mentee.

How to match few mentors with many mentees randomly using the modules of Drupal CMS?

There are many applicants to train and few to teach and this match has to happen randomly to avoid any one gaming the process. So we need a matching system which randomly allocates mentors to the mentees.

Any suggestions please.
