Encrypting and MACing different data with same key As a side question part of this. Is it safe to authenticate different data with the same MAC key? |

Is it possible to anonymize web traffic so that the IP Address cannot be determined while still being able to determine distinct IPs? You can authorize only owners of a secret key to encrypt with this key E(H(H(key||ip)) |

How to compare two datasets „anonymously”? There is no order in a privacy preserving set intersection protocol. Only equality |

Acceptable assumptions when prooving security If you assume that they are random you immediately are finished with the proof. In general you define how the ideal object of the cryptographic primitive you want to prove looks like. For instance for hash functions you assume the existence of a perfect hash functions with random output. Then going down into your construction you prove that your construction is close to the ideal one. For data confidentiality the proof of secure encryption schemes implies indistinguishability between given ciphertexts. This proofs are formulated with simulation games CPA,CCA,... |

How much data can I encrypt with AES before I need to change the key in CBC mode? These seem as notes from coursera Dan Boneh's crypto course |

Is Functional Encryption about Access Control over encrypted data alone? I explain you clearly with arguments on the base difference. Two constructions for different purposes. Argue for that and if you don't agree or i am mistaken explain please. don't cite |

Is Functional Encryption about Access Control over encrypted data alone? @sashank. There are no connections at all. In FHE you produce the encrypted version of an operation on encrypted data. In functional encryption you learn the result of a function applied on encrypted data |

CBC-MAC , fixed length, all blocks returned Why you want to do that? What is the scenario? |
