Patent abstract
In one embodiment, messages are encrypted with encrypted transformations that commute with one another. In another embodiment, a message is divided into message segments, and with each encrypted message segment one or more encrypted keys are sent. The encrypted keys may be used to decrypt a message segment that is sent at another time, such as the next message segment to be sent. In another embodiment, a sender encrypts a message with a first encryption, which may be unknown to the receiver. Then a receiver encrypts the message with a second encryption. Next the sender removes the first encryption, thereby allowing the receiver to reconstitute the original message by removing the second encryption.
