| Birthday Attack |
If a hacker wants to change a protected message (i.e., protected by a message digest) during its transmission to the intended recipient, but not have their changes be detectable by the receiver, the attacker could attempt to make numerous minor changes to the message and continually calculate the message digest after each minor change that they made. According to the principles of the birthday paradox, there is a probability that one of the variations on the messages digest will match the original and that variation could be implemented without raising suspicion. |

necessary. Additionally, Bridges are
