ABSTRACT:
A secure approach for sending a original message from a sender to a receiver. The sender may encrypt the original message by performing an XOR (or XNOR) operation of the original message and a first random message (same size as original message) on a bit by basis to generate a second message. The receiver may also perform an XOR of the second message with a locally generated second random message. The resulting message is sent to the sender system. The sender system may again perform XOR operation of the received message and the first random message, and send the resulting message to receiver. The receiver may perform XOR operation on the received output to generate the original message sent by the sender. Other technologies such as digital signatures and key pairs (public key infrastructure) may be used in each communication between the sender and receiver to further enhance security.
