Abstract

A computer generates a first encrypted message by encrypting an unencrypted message for decryption at a receiving device. The computer couples the first encrypted message with addressing data associated with the receiving device to generate a coupled message. The computer generates a second encrypted message by encrypting the coupled message for decryption at a data transmission service. The computer transmits the second encrypted message via the data transmission service to enable the receiving device to read the unencrypted message.
