I have invented the perfect security protocol that solves a major problem with 
the one-time-pad. The problem with most one-time-pad protocols is that you 
still need to have the pad around, creating a major security hole. I have 
solved that problem here. It has all of the steps of the usual one-time-pad 
plus an extra step.

1. Generate a random number the size of your data.
2. XOR your data with it.
3. Destroy the original data.

Here is the additional step:

4. Destroy the random number.

You can see now that no adversary can resonably reconstruct the plain text. 
This protocol might be terribly inconvenient, though, because it makes the 
origina data unaccessible. Oh well, just a necessary byproduct of 
theoritcally perfect security.

I hereby place this algorithm in the public domain. Use it freely.
