Network steganography conceals the transfer of sensitive information within unobtrusive data in computer networks. So‐called micro protocols are communication protocols placed within the payload of a network steganographic transfer. They enrich this transfer with features such as reliability, dynamic overlay routing, or performance optimization — just to mention a few. We present different design approaches for the embedding of hidden channels with micro protocols in digitized audio signals under consideration of different requirements. On the basis of experimental results, our design approaches are compared and introduced into a protocol engineering approach for micro protocols. Copyright © 2016 John Wiley & Sons, Ltd.
