Chosen ciphertext insecurity in an ElGamal variant Not 100% sure, but I think so. |

Chosen ciphertext insecurity in an ElGamal variant look at your "Diffie-Hellman and ElGamal" slides and/or see my answer below. |

Why do we assume un-security of communication channel on every cryptography system The point of the trusted certificate is to ensure that you are talking to who you think you're talking to. In other words, the point of this CA is to create an authentication channel to exchange keys. After the keys are exchange, the rest of the communication can occur over the fully unsecured channel. |

Is signing a hash instead of the full data considered secure? @PaŭloEbermann I've added that to the answer. |

What is a block cipher? @Thomas Thanks. That makes more sense. |

What is a block cipher? Typically that block gets padded with '0' until it's the correct blocksize. |

What is a block cipher? Well the block size and the keysize can be different. The blocksize is always the same for a given algorithm. If you have 512 bits of data and your block size is 256, you will need to break up the data into two chunks for encryptio/decryption. |
