A Resourceful Combined Block Cipher Mode of Operation for Packetised Network Communication

Abstract

In this paper a combined block cipher mode of operation is presented that provides an efficient authenticated encryption with associated-data (AEAD) security service for packet-based network communication. Using software simulation we show that our construct, called CYPHER-C3, achieves improvements in processing energy requirement, processing latency and packet throughput when benchmarked against the NIST recommended Counter with Cipher Block Chaining Message Authentication Code (CCM) scheme and the de facto wireless sensor network TinySec-AE scheme.
