We review most important secrecy amplification protocols that are suitable for ad-hoc networks of devices with limited resources, providing additional resistance against various attacks on used cryptographic keys without necessity for asymmetric cryptography. We discuss and evaluate different designs as well as approaches to create new protocols. A special focus is given to suitability of these protocols with respect to different underlying key distribution schemes and also to open issues. This technical report provides details of our research that will be presented at the 9th WISTP International Conference on Information Security Theory and Practice (WISTP`2015), where a subset of this technical report will be published in this conference proceedings.
