You might also try "Shamir's split key knowledge" which has been
around for many years and there is even a demo of how it works as
part of a great tool for introducing security, encryption and
similar bits at: http://www.cryptool.org/
I use the tool when teaching classes to executives and even they
can get it so you know it is pretty easy to follow. Very well
written explanations.
Best,
Allen
