[viff-devel] Homomorphic encryption

[Marc Makkes]

Hi Janus, 

The inclusion of multiple gmp.h and time.h is indeed a sloppy. This will
fixed in the next release. I'm currently working on there key generation
and some additional speedup. I hope to release it at the end of the
week. In addition I have some for key extraction and recomputing
methods. This make key storage a little easier. If you have any other
comments/suggestions please let me know. 

Kind regards, 

-Marc
