Hope you had a good vacation. Yes, very nice! I did not have any time yet to replace or test the code with in VIFF, this is mainly due have some other task that need some attention to. Ok. Also meaning there is a slight delay in the next release. I don't know if VIFF has a release sche

Hi Marc I am back from vacation and looking forward to the next release. Have you tried to replace the current uses of Paillier in VIFF with your code? On 03/08/2009, at 11.11, Marc Makkes wrote: Hi Janus, The inclusion of multiple gmp.h and time.h is indeed a sloppy. This will fixed

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.

Hi Claudio, Yes, It takes 496 msec on my machine. For timing i used the following: python -m timeit -s 'from pypaillier import generate_keys, encrypt' \ -s 'pk, sk = generate_keys(2048)' \ -s 'm = 98723498' \ 'encrypt(m, pk)' python -m tim

Hi Marc, Let me see if I understood the way you measured: it takes 496 msec on average to do an encryption with your code, right? Claudio On Fri, Jul 10, 2009 at 10:18 AM, Marc Makkes wrote: > Hi Janus, > > I think that I'd have reached the stage where you can test my code, but > still lacks som

Hi Marc, Thank you for your email. I will have a look at the code, when I get back from vacation two weeks from now. On 10/07/2009, at 10.18, Marc Makkes wrote: Hi Janus, I think that I'd have reached the stage where you can test my code, but still lacks some basic checks and is still

Hi Janus, I think that I'd have reached the stage where you can test my code, but still lacks some basic checks and is still prone to timing attacks and is basically the same viffs current implementation, with some additional speedups. So consequently, it code should only be used for testing pur
