Spix is a single-pass authenticated encryption algorithm that is designed by Riham AlTawy, Guang Gong, Morgan He, Kalikinkar Mandal, and Raghvendra Rohit. It authenticates both messages and header fields, and is designed to operate in constrained systems that can provide nonce uniqueness. It adopts a monkey duplexed Sponge-based mode of operation and provides a throughput of 81.8 Kbps for 1 KB messages. Moreover, it provides 128-bits security for both confidentiality and authenticity within a compact hardware area of 2406 GE. The underlying permutation of Spix is built from two of the well know and extensively cryptanalyzed constructions; Generalized Feistel Structure (GFS) Type II and the Simeck/Simon round function.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.
