Abstract

This paper begins by presenting an analysis of the current generic schemes utilising block cipher design techniques for the provision of authenticated encryption with associated data (AEAD) security services in communication protocols. Such protocols are commonly applied in wireless sensor networks. The conclusions of this analysis are used in the design of a resourceful AEAD construct, which we term Simultaneous Combined Mode Algorithm (SCMA). Using software simulation we show that our construct can achieve improvements in processing energy requirement, processing latency and data throughput when benchmarked against the analysed schemes.
