Abstract
In this paper, we describe the lightweight variant of the CAESAR
candidate π-Cipher, denoted as π16-Cipher, which provides working with
word sizes of 16-bits and security level of 96-bits or 128 bits. It is parallel,
incremental, nonce based, tag second-preimage resistant, authenticated
encryption cipher with associated data. The basic operations are ARX
(Addition, Rotation and XOR) operations. Its security relies on using
nonce as pair (PMN, SMN). The design of π-Cipher is highly parallel both
for the internal computing engine as well as for the whole crypto primitive.
In this paper we provide an optimized low area implementation for 16-bit
version of the π-function.
