Should we sign-then-encrypt, or encrypt-then-sign? @D.W , in encrypt-then-sign, If i encrypt with receivers public key and sign with my private key, then anybody knowing my public key ( say some auditor or a proxy agent) can first verify the signature for authenticity ( and drop it if does not match ) but only receiver can actually decrypt it |

Is there an authenticated encryption scheme where the recipient can attribute the message to a single sender? Your question is not very clear, are you looking for some symmetric encryption scheme that provides non-repudiation ? symmetric or asymmetric are encryption algorithms, where as non repudiation, integrity, confidentiality are properties of security system. few encryption algorithms may give these properties out of box, like Encrypting with one's private key may give non-repudiation and encrypting with someones public key would give confidentiality |

Can we construct fully homomorphic encryption scheme based on non-circuit approach? @mikeazo, circuit and non circuit is nothing but black box and non black box way of solving , see my answer below |

Reg:key Agreement Protocol you cannot generate keys using DH, and correct your question, using DH you cannot encrypt data using key agreement protocol, read about it first , rather than asking arbitrarily. If you are looking for quick code for something which you don't know what it should do this is not the place |

Is Porticor's “homomorphic” key encryption something that can really be done or is it just marketing hype? even i was skeptical, not sure why most of the companies are practicing off late this model to give our personal info in order to get a white paper , anyway am going through the document and i see there are few gaps in the analysis am not yet done though. May be they have consciously omitted few things for proprietary reasons |
