NIST lightweight cryptography competition

GIFT is used as subpcomponent of severalNIST lightweight cryptography competition candidates, notablyGIFT-COFB.

Documentations

The CHES 2017 paper can be found on theSpringer page (conference slideshere) and the updated and full version of the article is available onePrint. You can also findhere a work on threshold implementations of GIFT by Gupta et al.

Implementations

You can find test vectors and reference C implementations for both versions of GIFT on theGitHub repository of GIFT.

• Software

You can find in thisGitHub repository very efficient 8-bit AVR, 32-bit ARM Cortex-M3 and general 32-bit implementations of GIFT and Authenticated encryption GIFT-COFB.

• Hardware

You can find efficient reference, round-based and fully unrolled hardware implementations of GIFT onthis GitHub repository. You can also find extremly low-area hardware implementation onthis GitHub repository.
