The Welch-Gong (WG) stream cipher family was designed based on the WG transformation and is able to generate key streams with mathematically proven randomness properties such as long period, balance, ideal tuple distribution, ideal two-level autocorrelation and high and exact linear complexity. In this paper, the authors present a compact hardware architecture and its pipelined implementation of the stream cipher WG-16, an efficient instance of the WG stream cipher family, using composite field arithmetic and a newly proposed property of the trace function in tower field representation.
