comment Security of cloud computational protocols in UC Framework?
Good start Mike. Intuitively i feel there is some gap , may be in my understanding rather than your explanation. would get back in case more questions

comment Security of cloud computational protocols in UC Framework?
Well good question, MPC is too pessmestic , no party trusts other. in cloud computing only the server is not trusted . for example: we trust our friends on facebook but not facebook itself ! also in MPC all parties do computation , in CC only server does computation, so computational privacy should be modelled differently. Refer eprint.iacr.org/2013/272 for more such differences

may be a dumb question, what is difference between attacker and adversary ?

Mike , VC and Delegatable HE would allow to verify operations are performed or not . But we cannot restrict/narrow down the circuits that can be allowed to run. And yes FE is right choice for limiting functionality am trying to find ways of realizing FE with FHE

Thanks Reid , any idea why he suggested doing bit by bit

I did not get why he suggested doing bit by bit , any idea ? . my head is reeling with the possibilities of FHE already ! :)

it should be "access (control functionality)" i would correct it , the other one would be easy believe , rite ?
