1. A method for improving security of an electronic messaging system comprising: receiving a message input; using a processor, encoding said message input to provide ciphertext; with said processor, further transforming said ciphertext to disguise the ciphertext and make it appear to be similar or undistinguishable, at least by certain automated processes, from a natural language message; and transmitting said further-transformed ciphertext as a short message over an electronic network using a short-messaging protocol.
