Widespread use of pervasive devices has resulted in security problems which can not be solved by conventional algorithms and approaches. These devices are not only extremely resource-constrained, but most of them also require high performance – with respect to available resources – in terms of security, speed and latency. Especially for authenticated encryption, such performance can not be achieved with a standard encryption-hash algorithm pair or even a “block cipher mode of operation” approach. New ideas such as permutation-based authenticated encryption have to be explored. This scheme has been made possible by the introduction of sponge functions. Implementation feasibility of such an approach has yet to be explored. In this study, we make such an attempt by implementing the new
