While I have a basic understanding about one-time pads and how they work, I realize that there must be something wrong with this idea but I don't know enough to figure out what.
There are vast amounts of publicly available documents on the Internet. Why can't Alice and Bob agree that they will use the text of the first article posted on Slashdot after noon Central Standard Time each day that they have a message to send as their one time pad? In that way avoid the issue of having to transfer the pad between themselves in advance and they have a new text available daily.
Can someone explain to me why this isn't secure, assuming that the bad don't know that this is the text that they use for their one-time pad? If someone is going to beat it out of one of them, they will could beat a pre-exchanged one-time pad out of them too, so that can't be it.
