Random Coin Flip using ElGamal and a Trusted Party Wow, thanks. That makes perfect sense. What a beautiful answer. |

Random Coin Flip using ElGamal and a Trusted Party Oh right, so my comment is incorrect. Does the same sort of principle stand that if b = 0 then m = 1 and if b = 1, then m = g. If B knows that information, how can he use it to bias the value of the coin? |

Random Coin Flip using ElGamal and a Trusted Party Yeah, I think I have it figured out. Thanks for the help. g^b can be 1 or g. If it's 1, then A chose 0, if it's g, then A chose 1. |

For public-key encryption, why does COA resistance imply CPA resistance? I agree, can someone please explain the logic behind this? |

For public-key encryption, why does COA resistance imply CPA resistance? The attacker does not know the key, the attacker has a set of ciphertexts and the set of corresponding plaintexts. |
