Ascon, A Lightweight Cryptographic Suite for AEAD and Hashing

Overview

XIP2201B from Xiphera is an Intellectual Property (IP) core for Ascon authenticated encryption with associated data (AEAD) and hashing.

It supports three variants of AEAD as well as two variants of hashing and extendable output functions (XOF). Notably, XIP2201B provides three different cryptographic primitives all in one IP core. Ascon was selected by the National Institute of Standards and Technology (NIST) to be standardized as the lightweight cryptographic algorithm.

XIP2201B for authenticated encryption and decryption, hashing, and extendable output function operation for all Ascon variants defined in the standard.

Ascon was selected as the lightweight cryptographic algorithm by NIST and can thus be expected to see usage in the coming years. The algorithm itself is optimised to be small in size, support many features, and be especially efficient with small inputs.

The XIP2201B is optimised for both moderate resource usage and fast computation.

Key Features

Small Resource Requirements: XIP2201B requires 2009 Adaptive Lookup Modules (ALMs) (Intel® Cyclone® V E) or 2309 Lookup Tables (LUTs) (Xilinx® Artix-7). Contact sales@xiphera.com for ASIC resource requirements.
Versatile Algorithm Support: XIP2201B supports ASCON-128/128a/80pq/Hash/Hasha as well as XOF and XOFa. In other words, XIP2201B supports all parameterized algorithms defined in the standard.
Secure Architecture: The execution time of XIP2201B is independent of the input values and, consequently, provides full protection against timing-based side-channel attacks.
Standard Compliance: XIP2201B is compliant with Ascon specification 1.2 which is the version that was selected to be standardised by NIST.
Easy Integration: The 64-bit interface of XIP2201B supports easy integration to various systems.
