Abstract: A method, system and apparatus provides network communication between a sender and a receiver in a communication network. At a sender side of the network communication a ciphertext is encoded into a stegotext in a target language using a randomized language model, the ciphertext based upon an original content in a source language. The stegotext randomly generated by the language model to be decoupled from the original content and to have an assigned context in the target language that corresponds to the network communication in the target language. The stegotext is transmitted to a receiver over multiple communication channels of a communication network using one or more applications on an application layer of the communication network.
