[viff-devel] [PATCH 0 of 4] Insecure ElGamal based two player runtime

[Ivan Damgard]

Hi Guys,

About Claudio's latest proposal: I agree that this seems to be the 
natural solution given two parties and a homomorphic encryption 
scheme. As the homomorphic encryption scheme it would be interesting 
to try the scheme from mine, Martin's and Mikkel's paper. This would 
have to be the variant we propose for MPC where the order of one of 
the elements in the public key is a 2-power times a prime. It should 
be significantly faster than Paillier, although it is not clear how 
to make it actively secure in a really efficient way.


regards Ivan
