A method for secure transmission of a data message locks, at the sender, the data message using a first lock. The locked data message is transmitted to the receiver. Next, the locked data message is double-locked, at the receiver, using a second lock. Then, this double-locked data message is transmitted back to the sender. The first lock of the double-locked data message is then unlocked, at the sender, using a first key, leaving the data message single-locked by the second lock. The single-locked data message is transmitted back to the receiver, where the second lock of the single-locked data message is unlocked, using a second key, to generate the data message, completing the secure transmission.
