How does a chosen ciphertext attack work, with a simple example? Yeah that what I get too! I just cant see how it works in the chosen-ciphertext-attack scenario! I mean..the way I see it is that it really comes down to guessing in the end! |

How does a chosen ciphertext attack work, with a simple example? Ok! And how does the attacker then actually get the plaintext if he is not allowed to query the oracle on the ciphertext that was "sniffed"? |

How does a chosen ciphertext attack work, with a simple example? Are you not confusing it with CPA?? I thought that in a CCA attack the adversary submits 2 ciphertexts and gets the decryption of one of them! Also what exactly is the IND property? I know that it stands for indistinguishability but cant see how it relates! Does it have to do with the fact that the adversary sends 2 msgs and tries to tell them apart or...? |

How does a chosen ciphertext attack work, with a simple example? Ermm...Yeah I suppose that would count as communication! I think that for some particular schemes it is possible in theory but I cant figure out (or find anywhere) how this is achieved! |

How does a chosen ciphertext attack work, with a simple example? Yeah but it definitely requires some sort of "unprotected" communication though right? |
