Vernam cypher
An extremely secure cryptographic approach to enciphering messages, wherein each character of a message gets assigned a random character from the key; the one-time keypad is physically delivered to the receiver and then is destroyed. Note: The Vernam cypher requires the prospective user to first courier the megabyte key to the intended message partner. The Vernam cypher is the only provably secure (using information theory) crypto system.
