[Cryptography] Physical security risks of onetime pads just changed.

[Tom Mitchell]

The physical security rules of one time pads may have changed.

This may have risks when tamper evident devices for
nuclear launch code challenge response methods are considered.
The launch codes -- well that is a movie plot threat I hope.

Sending a pre-shared secret via US mail to establish
VPN and othersecure  remote office communication channels
may have gotten harder for high value government
and civilian organizations.

This implies that nine pages deep into a onetime pad
can be read in the lab... flip it over and it is 18 pages.
With luck flash paper pads would just ignite ;-)
