Title
On the implementation aspects of sponge-based authenticated encryption for pervasive devices
Abstract
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 SpongeWrap authenticated encryption schemes on all existing sponge functions and show that it is possible to realize a low-latency scheme in less than 6K gate equivalents at a throughput of 5 Gbps with a 128-bit claimed security level.
