Review of the White-Box Encodability of NIST Lightweight Finalists

May 9, 2022


Alex Charlès - University of Rennes


One of the main challenges cryptography needs to deal with is balancing the performances of a cryptographic primitive with its security. That is why in 2015, the National Institute of Standards and Technologies (NIST) has begun a standardization process to solicit the creation of new lightweight cryptographic algorithms. We then wondered which of this standardization finalists would suit the best to a white-box implementation.

To this end, we studied different algorithms structures on their encodability to later develop our white-box encoding solution. Afterwards, we reviewed the standardization finalists on the applicability of our solution to those algorithms, and finally apply it to GIFT, the permutation of GIFT-COFB.
